3.23.0:
    - Added selinux policy to allow cf-hub to initiate scheduled reports
      (ENT-10696, ENT-9825)
    - Added version_compare() policy function (CFE-3991)
    - Bodies can now inherit attributes containing global variables
      (CFE-4254)
    - Cached policy function results now take into account number of arguments
      and function name (CFE-4244)
    - Fixed infinite loop on error bug while reading interface exception file
    - Fixed inventoried policy release id when masterfiles-stage.sh deploys with cfbs
      (ENT-10832)
    - Improved locale override in masterfiles stage scripts (ENT-10753)
    - Improved syntax description for validjson() (ENT-9759)
    - Made cf-support use coredumpctl for core analysis only when configured in kerenl.core_pattern
      (ENT-9985)
    - Modified classesmatching() function to search parent bundles with inherit => true
      (ENT-5850)
    - Moved expected location of ignore_interfaces.rx from $(sys.inputdir) to
      $(sys.workdir). If the file is found in $(sys.inputdir) but not in
      $(sys.workdir), we will still process it for backwards compatability,
      but issue a warning prompting the user to move it to the appropriate
      location. (ENT-9402)
    - Only CFEngine processes are now killed as expired lock owners
      (CFE-3982)
    - SELinux no longer blocks CFEngine deamons in reading security parameters from /proc/sys/kernel
      (ENT-9684)
    - cf-hub is now allowed to use the TLS kernel module on
      SELinux-enabled systems (ENT-9727)
    - cf_lock.lmdb is no longer restored from backup on
      every boot (CFE-3982)
    - packagesmatching() and packageupdatesmatching() now look for the software
      inventory databases in the state directory and use them if found. This
      change enables the usage of these functions in standalone policy files
      without the demand for specifying the default package inventory attribute
      in body common control. However, you still need the default package
      inventory attribute specified in the policy framework for the software
      inventory databases to exist in the first place and to be maintained.
      (ENT-9083)
    - CFEngine locks are now purged dynamically based on the local locks DB
      usage/size ranging from no purging (<=25% usage) (ENT-8201, CFE-2136, ENT-5898)
    - `cf-check repair` now rotates DB files with high usage (>95%) (CFE-3374)

      empty LMDB files (ENT-8201)
    - `cf-check repair` now supports the `--test-write` option to check if DBs can
      be written to as part of identifying DBs that need repairing (CFE-3375)
    - `cf-check diagnose` now shows DB usage and a hint if rotation is required
    - /usr/bin/getent is now attempted to be used if /bin/getent doesn't exist (CFE-4256)

      systemd-based systems (ENT-8456)
    - edit_line bundles can now use the new
      $(edit.empty_before_use) variable mirroring the value of
      edit_defaults=>empty_before_use of the related files promise
      (ENT-5866)
    - Package modules with unresolved variables in their
      names are now skipped in package queries (ENT-9377)

      (ENT-8824)
    - 'meta' attribute can now be used in custom promises (CFE-3440)

    - Fixed git_cfbs_deploy_refspec in masterfiles_stage leaving temp dir
      (ENT-9039)


3.20.0:
    - 'rxdirs' now defaults to "false". This means that the read permission
      bit no longer implies execute bit for directories, by default.
      Permission bits will be exactly as specified. To restore the old behavior
      you can still enable 'rxdirs' explicitly. (CFE-951)
    - 'N' or 'Ns' signal specs can now be used to sleep
      between signals sent by 'processes' promises
      (CFE-2207, ENT-5899)
    - Directories named .no-distrib are no longer copied from policy server
      (in bootstrap/failsafe) (ENT-8079)
    - Files promises using content attribute or template method now create
      files by default unless `create => "false"` is specified. (CFE-3955,
      CFE-3916)
    - template_method mustache and inline_mustache now create file in promiser,
      if template rendering was successfull and file does not exist. (ENT-4792)
    - Added support for use of custom bodies in custom promise types
      (CFE-3574)
    - Custom promise modules now never get promise data with unresolved variables
      (CFE-3434)
    - Custom promises now use standard promise locking and support ifelapsed
      (CFE-3434)
    - Enable comment-attribute for custom promise types (CFE-3432)
    - cf-secret encrypt now encrypts for localhost if no key or host is
      specified (CFE-3874)
    - CFEngine now builds with OpenSSL 3 (ENT-8355)
    - CFEngine now requires OpenSSL 1.0.0 or newer (ENT-8355)
    - Moved Skipping loading of duplicate policy file messages from VERBOSE to DEBUG
      (CFE-3934)
    - CFEngine processes now try to use getent if the builtin user/group
      info lookup fails (CFE-3937)
    - No longer possible to undefine reserved hard classes (ENT-7718)
    - Unspecified 'rxdirs' now produces a warning (CFE-951)
    - Fixed wrong use of log level in users promises log messages (CFE-3906)
    - Fixed default for ignore_missing_bundles and ignore_missing_inputs
      The issue here was that these attributes should default to false,
      but when they are assigned with an unresolved variable, they
      would default to true. (ENT-8430)
    - Added protocol 3 (cookie) to syntax description (ENT-8560)
    - Moved errors from data_sysctlvalues from inform to verbose (CFE-3818)
    - Fixed inconsistencies with methods promises and missing bundles
      Previously, methods promises acted differently depending on if
      you specify the bundle with usebundle or in the promiser string.
      This change removes the inconsistent checking which was only
      happening on promises with usebundle. It also ensures that
      the agent will abort if trying to use an undefined bundle,
      regardless of whether it was using promiser string or usebundle.
      This change, combined with the fix for ignore_missing_bundles
      and ignore_missing_inputs, allow you to use inputs and bundles
      conditionally (like we do for the enterprise federation policy)
      and still have the agent abort in the correct situations
      (when a bundle is actually missing and you haven't enabled
      ignore_missing_bundles). The downside is that there are some
      potential situations where undefined bundles would be detected
      earlier previously (both correctly and incorrectly).  (ENT-8430)

    - Trailing commas can now be used in policy argument lists (CFE-3734)
    - Changed cf-key option --print-digest to take an optional argument.

    - Added checks to return value from getpwuid & getgrgid (CFE-3521)
    - Added int() policy function (CFE-3616)

      (ENT-5125)
    - Added files promise content attribute (CFE-3276)
    - Added string_trim() policy function (CFE-3074)
    - Added warning if CSV parser parses nothing from non-empty file
      (CFE-3256)
    - All changes made by 'files' promises are now reported. Also,
      directory and file creations are now properly reported as 'info'
      messages. And failures in edit_xml result in promises marked as
      failed not interrupted. Purged dirs and files are reported as
      repaired (ENT-5291, CFE-3260)
    - Bootstrap to loopback interface is now allowed, with a warning
      (CFE-3304)
    - Client initiated reporting was fixed on RHEL 8.1 (ENT-5415)
    - Fixed rare crashing bug when parsing zombie entries in ps output. The
      problem was only ever observed on AIX, but could theoretically happen
      on any platform depending on exact libc behavior. (ENT-5329)
    - Fixed an issue causing duplicate entries in sys.interfaces, and
      sys.hardware. (CFE-3046)
    - Fixed ifelse() to return fallback in case of unresolved variables
      (ENT-4653)
    - Fixed locking of promises using log_repaired / log_string with
      timestamps (CFE-3376)
    - Fixed memory leak in handling of inline JSON in policy evaluation
    - Fixed memory leak in readlist functions (CFE-3263)
    - Fixed race condition when multiple agents are acquiring critical
      section locks simultaneously (CFE-3361)
    - Fixed selection of standard_services when used from non-default
      namespace (ENT-5406)
    - Fixed service status cfengine3 on systemd managed hosts (ENT-5528)
    - Fixed some memory leaks and crashes in policy evaluation (CFE-3263)
    - Improved error message for invalid body attribute names (CFE-3273)
    - Improved management of secondary groups to avoid intermediary state
      failures (ENT-3710)
    - LMDB files are now created with correct permissions (ENT-5986)
    - Log messages about broken Mustache templates are now errors (CFE-3263)
    - Made classfiltercsv() fail properly on invalid class expression index
    - Measurements promises with no match no longer produce errors
      (ENT-5171)
    - Moved error reading file in countlinesmatching() from verbose to error
      (CFE-3234)
    - Added new data validation policy functions validdata() and validjson()
      (CFE-2898)
    - New version checking convenience policy functions (CFE-3197)
      Added the following policy functions to check against local CFEngine version:
      - cf_version_maximum()
      - cf_version_minimum()
      - cf_version_after()
      - cf_version_before()
      - cf_version_at()
      - cf_version_between()
    - Removed (USE AT YOUR OWN RISK) from cf-key help menu for -x (ENT-5090)
    - Rewrote helloworld.cf to use files promises content attribute
      (CFE-3276)
    - The outcome classes are now defined for the top-level directory when
      'include_basedir' is 'false' (ENT-5291)
    - Variable references with nested parentheses no longer cause errors
      (CFE-3242)
    - cf-check: Added a more user friendly message when trying to print
      unknown binary data (ENT-5234)
    - cf-check: Added data validation for cf_lastseen.lmdb (CFE-2988)
    - cf-check: Added nice printing for nova_agent_executions.lmdb
      (ENT-5234)
    - cf-check: Added validation for timestamps in cf_lock.lmdb (CFE-2988)
    - cf-check: Added validation for timestamps in lastseen.lmdb (CFE-2988)
    - cf-check: Fixed issue causing repair to target the wrong database file
      (ENT-5309)
    - cf-check: Symlinked LMDB databases are now preserved in repair
      Performs diagnosis and repair on symlink target instead of symlink.
      Repaired files / copies are placed alongside symlink target.
      In some cases, the symlink target is deleted to repair a corrupt
      database, and the symlink is left as a broken symlink. This is
      handled gracefully by the agent, it will be recreated. Broken
      symlinks are now detected as an acceptable condition in diagnose,
      it won't try to repair them or delete them. (ENT-5162)
    - storage promises managing nfs mounts should now correctly mount
      after editing fstab entries

3.15.0:
    - New policy function basename() added (CFE-3196)
    - Added read_module_protocol() policy function
      This function reads module protocol from a file, and can be used
      for caching the results of commands modules. (CFE-2973)
    - The @ character is now allowed in the key of classic arrays defined
      by the module protocol (CFE-3099)
    - nth() policy function now supports negative indices (CFE-3194)
    - Fixed .xy floating point numbers parsing in eval() (CFE-2762)
    - Added inform constraint to commands promises, to allow suppression of
      INFO log messages (CFE-2973)
    - Changed unless constraint to be more consistent with if
      For any situation where if would NOT skip a promise, unless
      will cause the promise to be skipped. When there are
      unresolved variables / function calls, if will skip, unless
      will NOT skip. (CFE-3160)
    - Default minimum allowed TLS version is now 1.1 (ENT-4616)
    - Network protocol version 2 is now called "tls"
      "tls" or "2" can be used in places where you specify network
      protocol. Log messages were altered, to show "tls" instead of
      "latest". (ENT-4406)
    - Introduced protocol version 3 - "cookie"
      This protocol is identical to version 2 ("tls"),
      except it allows the enterprise reporting hub to send
      the COOKIE command to enterprise hosts. This command is used for
      detecting hosts using duplicate identities. Protocol version "latest"
      now points to version 3. For community installations, it should not
      make a difference, policy servers will not send this command. The only
      visible difference is the new version number (in logs and policy).
      (ENT-4406)
    - Package modules now hit network when package cache is first initialized
      (CFE-3094)
    - Fixed promise skipping bug in unless (CFE-2689)
    - Fixed error message for unexpanded variables in function calls in unless
      (CFE-2689)
    - Prevented buffer overflow when policy variable names are longer than
      1024 bytes
    - Zero bytes in class guards no longer cause crashes (CFE-3028)
    - Fixed bug in ps parsing on OpenBSD / NetBSD causing bootstrap to fail
    - Fixed crash in policy/JSON parsing of numbers with too many decimal
      points (CFE-3138)
    - copy_from without preserve now respects destination mode (ENT-4016)
    - Removed stime_range and ttime_range constraints from promise hash
      (ENT-4921)
    - Fixed promise result when using process_stop in processes type promises
      (ENT-4988)
    - cf-execd now sends SIGKILL to the agent process in case of
      agent_expireafter, after attempting SIGINT and SIGTERM (CFE-2664)
    - cf-serverd now tries to accept connection multiple times (CFE-3066)
    - Fixed multiple measurements tracking growth of same file (ENT-4814)
    - Set create permissions of monitord files in state directory to 0600
      0600 matches the permissions enforced by policy.
      Affected files:
       * state/cf_incoming.*
       * state/cf_outgoing.*
       * state/cf_users
       * state/env_data
      (ENT-4863)
    - Clarified descriptions of io_writtendata and io_readdata (ENT-5127)
    - Clarified log message about process_count and restart_class being used
      concurrently (CFE-208)
    - Agent runs that hit abortclasses now record results (ENT-2471)
    - An ID of rhel in os-release file will now define both rhel and redhat
      classes (CFE-3140)
    - Version specific distro classes are now collected by default in
      Enterprise (ENT-4752)
    - redhat_8 and redhat_8_0 are now defined on RHEL 8 (CFE-3140)
    - Added derived-from-file tag to hard classes based on /etc/redhat-release
      (CFE-3140)
    - Added sys.bootstrap_id policy variable containing the ID from
      /var/cfengine/bootstrap_id.dat, if present (CFE-2977)
    - sys.interfaces now contains interfaces even when they only have
      IPv6 addresses (ENT-4858)
    - IPv6-only interfaces added to sys.hardware_(addresses,mac) (CFE-3164)
    - IPv6 addresses are now added to policy variable sys.ip_addresses
      (CFE-682)
    - IPv6 addresses now respect ignored_interfaces.rx (CFE-3156)
    - Hostname now allowed in bindtoaddress (CFE-3190)
    - Fixed issue when removing comments from files in various policy functions
      This also fixes many erroneous occurences of the error message
      mentioning:

         [...] because it legally matches nothing

      (A warning can still appear if a comment regex actually matches nothing).
      Also made this comment removing logic faster.
      Affected functions include:
      * readstringlist()
      * readintlist()
      * readreallist()
      * peers()
      * peerleader()
      * peerleaders()
      * data_readstringarray()
      * data_readstringarrayidx()
      * data_expand()
      * readstringarray()
      * readstringarrayidx()
      * readintarray()
      * readrealarray()
      * parsestringarray()
      * parsestringarrayidx()
      * parseintarray()
      * parserealarray()
      (CFE-3188, ENT-5019)
    - Fixed memory leak in JSON / env file parsing (CFE-3210)
    - Fixed memory leak in handling of nfs / fstab (CFE-3210)
    - Fixed memory leak in string_replace() and regex_replace() (CFE-3210)
    - Fixed memory leak when using with constraint (CFE-3210)
    - Fixed minor memory leak in policy evaluation (CFE-3210)
    - Fixed small memory leak in SQL database promises (CFE-3210)
    - Received SIGBUS now triggers a repair of local DBs (CFE-3127)
    - Corrupted LMDB files are now automatically repaired (CFE-3127)
    - Keys in the lock database, cf_lock.lmdb, are now human-readable
      (CFE-2596)
    - Local databases now use synchronous access on AIX and Solaris (ENT-4002)
    - Report corrupted local database with a critical log message (CFE-2469)
    - Local DB errors are now logged with the particular DB file path (CFE-2469)
    - cf-check: repair now preserves readable data in corrupted LMDB files
      (CFE-3127)
    - cf-check: --dump option was added to the backup command
    - cf-check: Added --no-fork to diagnose command (CFE-3145)
    - cf-check: Added -M manpage option and other common options (CFE-3082)
    - cf-check: No DB files in state dir now causes errors
    - cf-check: dump command now dumps DB contents to JSON5 (CFE-3126)
    - cf-check: help command can now take a topic as argument

3.14.0:
    - A bootstrap_id.dat file is now generated on every bootstrap
      (CFE-2977)
    - Added options to cf-net to set minimum TLS version and ciphers
      (ENT-4617)
    - Added --no-truncate option to cf-key
      This option, when used with --show-hosts changes the formatting
      of the output. Instead of padding and truncating each of the
      fields, they are printed, in full, with no padding, and separated
      by a single tab character. The output is not as pretty, but should
      be more useful for parsing by other scripts / tooling. (CFE-3036)
    - Added a new option --skip-db-check to agent and execd
      This option allows you to enable/disable database (LMDB) consistency
      checks. Initially it is disabled by default, but this will likely
      change. (CFE-2893)
    - Added a new utility to contrib: cf-remote
      cf-remote is a python + fabric tool to log in to remote hosts
      you have ssh access to. It can be used to download, transfer,
      and install CFEngine packages as well as bootstrapping etc.
      At this point, cf-remote is not packaged with CFEngine, but can be
      installed separately from:
      https://github.com/cfengine/cf-remote
      (CFE-2889)
    - Added derived-from-file tags to hard classes based on /etc/debian_version and /etc/issue
    - Added a function to filter CSV-files by classes (CFE-2768)
    - Forward slash is now an allowed character in module protocol commands
      (CFE-2478)
    - Augments files can now handle class expressions by appending '::'
      A condition in an augments file is treated as a class expression
      if it ends in ::. Otherwise it is treated as a regular
      expression. (CFE-2954)
    - Internal ps command can now handle longer usernames (CFE-2951)
    - Made copylink_pattern honor '/../' in copy source (CFE-2960)
    - CSV parser now supports CRLF inside double quotes (ENT-4504)
    - Added an error when a function defining a variables still fails at
      pass 3 (CFE-2983)
    - Documented cf-execd and cf-serverd response to SIGHUP in manpage
      (CFE-2853)
    - Stopped trimming leading zeroes in ubuntu minor version class
      The old version detection logic (using /etc/debian_version) was
      converting the minor version part to an integer, defining
      ubuntu_18_4 instead of ubuntu_18_04. The new platform detection
      (based on /etc/os-release) defines ubuntu_18_04. Since both old
      and new methods are running to maximize compatibility, both
      ubuntu_18_04 and ubuntu_18_4 were defined.
      This commit ensures that the old detection logic treats the
      minor version (the 04 part) as a string, not an integer. The
      change is specific to Ubuntu, and should affect Ubuntu 18.04,
      16.04, 14.04, etc. (CFE-2882)
    - SUID log permissions are now properly enforced (CFE-2919)
    - Agent log file names are now always lowercase
    - Extended module with file protocol for data (CFE-3050)
    - Fixed a segfault in 'cf-promises -p json-full' (CFE-3019)
    - Added cf-key help output to indicate ability to delete by key digest
      (CFE-2997)
    - Fixed disabling TLS 1.0 (CFE-3068)
    - Fixed growing memory footprint of daemons (CFE-3032)
    - Fixed the log message about setting collect_window (ENT-4238)
    - Fixed the log message when parsing TIME in 'ps' output fails
    - Fixed parsing of YAML values starting with numbers (CFE-2033)
    - Fixed sys.flavor on AIX (ENT-3970)
    - Fixed 6 cases where promises could get the wrong outcome
      All cases were related to error handling and detected using
      static code analysis (LGTM). They were limited to cf-monitord
      and cf-agent (guest_environments and files promise types). Due
      to a programming mistake, promise results would sometimes be
      overwritten with 'skipped' outcome. Keeping the previous
      value or making the promises 'not kept' is expected behavior.
      Added a query to our CI (LGTM) to make sure we catch this error
      on new contributions.
    - Fixed an issue while parsing ps output on AIX (ENT-4295)
    - Fixed a memory leak in filesexist function (ENT-4313)
    - Fixed a memory leak in mustache rendering (ENT-4313)
    - Fixed a memory leak in: differences(), intersection(), unique()
      (ENT-4586)
    - Fixed a segfault in policy parser (ENT-4022)
    - Connection cache is now global (CFE-2678)
    - Increased verbosity of AcquireLock permission error (ENT-4395)
    - Message about invalid class characters from module protocol moved to VERBOSE
      (CFE-2887, CFE-3008)
    - Prevented buffer overflows in cf-monitord data parsing
    - Private keys generated by cf-key are no longer encrypted
      Private key files encrypted with a broken cipher and default
      hard coded passphrase provide no real security, and is only an
      inconvenience. Maybe it was intended to add a password prompt
      later, but it's been 10 years now, and the cipher and passphrase
      remain untouched. The function which reads keys still supports
      both encrypted and unencrypted keys, it will decrypt if necessary.
    - Reduce SSL/TLS shutdowns on bad networks (CFE-3023)
    - Removed programming error in handling of process_count body
      Previously, having a failing function call inside in_range_define
      or out_of_range_define would cause a programming error when
      trying to define that as a class. Fixed it by detecting the
      case, printing a normal error, and skipping defining the class. (CFE-2067)
    - Set policy->release_id to "failsafe"/"bootstrap" when running failsafe.cf
      (CFE-3031)
    - Switched permissions of various temporary files in state to 0600
      These files were created with 0644 permissions, and then
      repaired in policy. However, since they are deleted / recreated
      periodically, it causes INFO noise. Safer and better user
      experience to create them with restricted permissions to
      begin with.
      Affected files:
      * $(sys.statedir)/cf_procs
      * $(sys.statedir)/cf_rootprocs
      * $(sys.statedir)/cf_otherprocs
      (ENT-4601)
    - string_split segments are now truncated to 1024 bytes instead of
      crashing (CFE-3047)
    - Unresolved function calls in process_select body are now skipped
      Function calls which always fail, like getuid("nosuchuser"), are
      never resolved. Previously this would cause a programming error,
      since the body is expected to have a list of strings, not
      unresolved function calls.
      The function calls are silently skipped (with a verbose message)
      as this matches the behavior of calling the functions in a vars
      promise, and using that as a body parameter.
      (CFE-1968)
    - cf-check directories can now be controlled from ENV vars (CFE-2994)
    - cf-check: Added backup command
      This command copies lmdb files to a timestamped backup directory.
      (ENT-4064)
    - cf-check: diagnose and backup now use state directory by default
      (ENT-4064)

3.13.0:
    - Add support for TLS 1.3 and its ciphersuites
    - Add 'feature' hard classes for supported TLS versions
      Different versions of TLS are supported depending on what version
      of OpenSSL CFEngine was compiled and linked with. Newly added
      feature hard classes bring that information to the
      policy. Classes like these are now defined (for supported
      versions of TLS):
      feature_tls                     source=agent,hardclass
      feature_tls_1                   source=agent,hardclass
      feature_tls_1_0                 source=agent,hardclass
      feature_tls_1_1                 source=agent,hardclass
      feature_tls_1_2                 source=agent,hardclass
      feature_tls_1_3                 source=agent,hardclass
    - Add a new variable $(sys.default_policy_path)
      A new sys variable that provides the path of the default policy
      file evaluated when no file is specified with the '-f' option.
    - Add an option to skip the initial policy run on bootstrap
      In some cases it may not be desired to run the policy as the last
      step of the bootstrap. This can be done with the new
      '--skip-bootstrap-policy-run' option for cf-agent. (CFE-2826)
    - Trigger promises.cf as the last step of bootstrap (CFE-2826)
    - Add support for overriding the package module's path (CFE-2103)
    - Add support for setting package module interpreter (CFE-2880)
    - Added --log-level option to all components
      This allows you to specify any log level (info, verbose, debug etc.).
      It is also less strict, allowing different spelling. As an example,
      --log-level i, --log-level INFO, --log-level inform are all the same.
    - Added a new binary: cf-check
      Corrupt local databases (LMDB) continues to be a problem.
      cf-check will be used to diagnose and remediate problems
      with corrupt databases. It is a standalone binary, which
      doesn't evaluate policy or use the local databases, thus
      it can be used in situations where the other binaries
      like cf-agent would hang.
      cf-check replaces our lmdb database dumper, lmdump.
      cf-check lmdump or symlinking / renaming it to lmdump
      will make cf-check have the exact same behavior as lmdump.
      cf-check will include much more functionality in the future
      and some of the code will be added to other binaries,
      for example to do health checks of databases on startup.
      Ticket: (ENT-4064)
    - Added function string_replace. (CFE-2850)
    - Allow dots in variable identifiers with no such bundle
      As described and discussed in CFE-1915, defining remote variables
      (injecting variables into remote bundles) is dangerous and must
      be blocked. However, using a dot-separated common prefix for
      variables raises no security concerns and can be considered
      valid. (CFE-1915)
    - Allow requiring TLS 1.3 as the minimum version
    - Apply augments after vars, classes and inputs in def.json
      (CFE-2741, CFE-2844)
    - Bundle name is now part of the log message when aborting a bundle
      (CFE-2793)
    - Class names set by module protocol are automatically canonified
      (CFE-2877, CFE-2887)
    - Classes failsafe_fallback and bootstrap_mode are now reported by default
    - Correct log level for data_readstringarray* (CFE-2922)
    - Do not iterate over JSON objects' properties in mustache (CFE-2125)
    - Do not render templates when passed invalid data (CFE-2194)
    - Eliminated error messages caused by attempting to kill expired processes
      (CFE-2824)
    - Fix cf-runalerts systemd unit conditions so the service will run
      (ENT-3929)
    - Fix the off-by-one error in cf-runagent background process spawning
      (CFE-2873)
    - Fixed OOB read / heap buffer overflow in evaluator (ENT-4136)
    - Fixed a memory leak which occured when reloading RSA keys from disk
      (CFE-2857)
    - Fixed a memory leak which occured while loading augments files
      (CFE-2913)
    - Fixed an issue with splay time in cf-execd (CFE-2931)
    - Fixed error handling and memory leak in cf-key (CFE-2918)
    - Fixed memory leak in JSON to policy conversion (ENT-4136)
    - Fixed memory leak in lmdb cleanup (CFE-2918)
    - Fixed memory leaks in cf-agent during bootstrap (CFE-2918)
    - Fixed memory leaks in variablesmatching() and findfiles() (CFE-2918)
    - Fixed missing class with mustache templates in warn_only mode
      (CFE-2600)
    - Fixed small memory leak in cf-serverd (CFE-2918)
    - Fixed small memory leak in cf-upgrade (ENT-4136)
    - Fixed small memory leaks of environment variable strings (CFE-2918)
    - LMDB database dumper, lmdump, no longer creates empty databases
      (ENT-4064)
    - Made variablesmatching functions treat args regexes more correctly
      variablesmatching() and variablesmatching_as_data() no longer
      use string comparison to find matches. The documentation is clear;
      arguments should be regexes (so you have to escape special
      characters).

              "myvar"
                string => "example",
                meta => {"os[linux]"};
              "matches"
                slist => variablesmatching(".*", "os\[linux\]");
            reports:
              "Match: $(matches)";
          }
      The above example is correct. If you don't escape the brackets
      like above, it will no longer work. (You probably shouldn't use
      brackets in tags anyway).
    - Prevent the init script from managing processes inside containers
      (ENT-3800)
    - Read mustache-rendered files in text mode when comparing digest
      (ENT-2526)
    - Reload persistent classes on config reload in cf-execd and cf-serverd
      (CFE-2857)
    - Fixed issue with @if macro failing when it is on the first line.
      (CFE-2817)
    - Fixed issue with cf-agent intermittently hanging on windows
      sometimes (ENT-3756)
    - Change GIT_BRANCH to GIT_REFSPEC and remove Design Center vars
      (ENT-4023)
    - os-release file is now used for hard classes and sys.flavor on all linuxes
      This will improve platform detection on newer operating systems where
      /etc/os-release (or /usr/lib/os-release) is present.
      A hard class will be set for the value of the ID key (canonified with
      underscores), if it exists. If both ID and VERSION_ID exist, multiple
      hard classes will be set for all parts of the version number. The
      special variable sys.flavor will also be set by determining major
      version from VERSION_ID.
      Example os-release file:
        ID=coreos
        VERSION_ID=1185.3.0
      For the example above, sys.flavor will be coreos_1185 and 4 hard
      classes will be set; coreos_1185_3_0, coreos_1185_3, coreos_1185,
      and coreos.
      For backwards compatibility, older distribution specific logic is still
      executed and may overwrite sys.flavor and define hard classes as before.
    - Refactor use of atexit to use custom cleanup function instead. On Windows
      atexit() unloads DLLs before and/or during atexit functions being called
      which causes bad behavior. (ENT-3756)

3.12.0b1:
    New Features:
    - Add a --key-type option to specify RSA key size to cf-key
    - New hash_to_int policy function (CFE-2733)
    - Issue a warning on ignored locking attributes (CFE-2748)
    - Add IPv6 hard classes with the "ipv6_" prefix (CFE-2310)
    - Introduce "missing_ok" attribute in body copy_from
      This allows to ignore missing sources in file copy operations (CFE-2365)
    - Enable Xen hypervisor detection on all x86 platforms (CFE-2203)
    - Add sys.policy_entry variables (CFE-2572)
    - Added inline_mustache template method (CFE-1846)
    - New component cf-net (cf-net is a CLI for the CFEngine network protocol,
      useful for debugging, testing etc) and accompanying policy variable
      sys.cf_net containing path to cf-net binary

    Changes:
    - Load augments at the end of context discovery
      This means that classes defined as part of the context discovery
      (e.g. 'am_policy_hub' and 'policy_server') can be used in the
      augments (CFE-2482)
    - Open measurements promise type from enterprise cf-monitord
    - Transform filesexist() into a collecting function (CFE-2744)
    - Load process table when actually needed for a processes promise (ENT-2536)
    - Ignore commented out entries in fstab when edit_fstab is true (CFE-2198)
    - Do not move obstructions in warn policy mode (CFE-2740)
    - Made the max bytes parameter to file reading functions optional (CFE-2656)
    - Do not tag large volatile variables for inventory
      sys.interfaces_data, sys.inet and sys.inet6 are commonly larger than the
      maximum data size allowed to be collected by cf-hub. Data larger than 1k
      is truncated. Instead of reporting truncated data this change stops
      tagging the variable so that it will not be collected to the Enterprise
      hub and will not be available in Mission Portal. (ENT-3483)
    - cf-execd now re-parses augments on policy reload (CFE-2406)
    - Improve misleading verbose message
      For constraints if/ifvarclass/unless, we now print the whole rval of the constraint.
      Previously the message was just "skipping variable because ifvarclass is not defined" while the variable itself was defined.
      Old message example:
        verbose: Skipping promise 'mailto' because 'if'/'ifvarclass' is not defined
      Changed to:
         verbose: Skipping promise 'mailto' because 'ifvarclass => not(isvariable("mailto"))' is not defined
      (CFE-2697)
    - Promise comments for file changes moved to verbose (ENT-3414)
    - Suppress output from systemctl based restart of services in
      bootstrap/failsafe (CFE-1459)
    - Parser can now handle larger inbut buffers (CFE-1886)
    - Improve logging of ACL errors (ENT-3455)
    - cf-execd systemd service now only kills cf-execd itself (ENT-3395)
    - Load multiple augments from "augments" string array in def.json
      (CFE-2084)
    - Improve support for Alpine Linux
    - Set the exit value when running cf-key
      When running cf-key to generate new keys, set the exit value of the
      program to be 0 on success and 1 on failure. This makes it easier to
      catch errors during setup of a new machine.
      Change the default behavior of the program to not write anything to stdout,
      opting to use the Log() function which can write to stdout and will also
      allow output to be sent to syslog.
      Add a --inform option to set the global log level to LOG_LEVEL_INFO.
      Change the permissions of the randseed file to 600 and catch the exception
      if the chmod call fails.
    - Properly reverse-resolve DNS names longer than 63 chars (ENT-3379)
    - Properly redirect init script to systemd on debian systems (ENT-3326)

    Bug fixes:
    - Disallow modifications of variables from a remote bundle (CFE-1915)
    - Speedup evalution by not copying variables table when expanding a promise
      (CFE-2524)
    - Resolve subkey conflicts when converting to JSON
      Whenever there is a conflict of array variable definitions prefer
      the container subkeys over simple values when converting to JSON
      (CFE-2536)
    - Do not ignore meta promises in server bundles (CFE-2066)
    - Add a debug log for computed class in splayclass
    - Don't error when calling isexecutable on broken link (CFE-741)
    - Fix segfault when no show-evaluated-vars/classes is specified
    - Fix memory leak in cf-execd, triggered when sending email failed (CFE-2712)
    - Fix IPv6 parsing to be un-reversed (CFE-2580)
    - Fix bug preventing permission changes on Unix sockets (CFE-1782)
    - Fix storage mount promise when existing mountpoint has a similar path
      (CFE-1960)
    - Fix segfault when cf-promises -p is called against a file with syntax
      errors (CFE-2696)
    - Fix rare cf-execd hang (CFE-2719)
    - Fix mergedata segfault when called on a non-container (CFE-2704)
    - Do not segfault if policy_server.dat only contains whitespaces and/or line breaks
    - Fix segfault on JSON policy files with no bundles and bodies (CFE-2754)


3.11.0:
    New Features:
    - Allow function calls in promiser using universal "with" attribute
      (CFE-1092)

    - Detect Amazon Linux and set "AmazonLinux" hard class and
      sys.flavour variable
    - New sysctlvalue() and data_sysctlvalues() functions from /proc/sys
      (CFE-2513)
    - readdata() also auto-detects .yml files as YAML
    - Added support for ENV and CSV file parsing (CFE-1881)
    - Added vars and classes for CoreOS (ENT-3043)
    - cf-agent: implement --show-evaluated-vars and --show-evaluated-classes
    - Support for custom ports and host names as policy hub (CFE-953)
    - cf-promises: allows --show-vars and --show-classes to take an optional filter
    - Added a new tool: cf-net. cf-net is a CLI for the CFEngine
      network protocol, useful for debugging, testing etc (CFE-2493)
    - New policy variable: sys.cf_net contains path to cf-net binary
    - Read /etc/os-release into sys.os_release (CFE-1881)

    Changes:
    - readintlist() now prints an error if the
      file contains real numbers, not integers, and aborts; previously it was
      printing an info-level error message, was half-reading an integer out of
      the real, and was continuing successfully.
    - "make tar-package" should create a tarball with the contents of
      "make install" (ENT-3041)
    - Allow opening symlinks owned by root or by the current user
      (CFE-2516)

    - readstringlist(), readintlist(), readreallist(): Print
      verbose instead of error message if file can not be read
    - cf-serverd: Do not close connection when file does not exist
      (CFE-2532)
    - policy_server.dat now appends a newline and supports host & port
    - Allow string_head and string_tail to take negative arguments
    - getvalues(inexistent_var) returns an empty list.
      Restores 3.7.x and earlier behaviour. (CFE-2479)
    - Partially restore old getvalues(array) behaviour
      Bugfix: getvalues() now behaves correctly for old CFEngine
      arrays of depth 1
      Behaviour change: it always returns a list now. Even when v is a simple
      string (i.e. not an iterable) it will return an slist with one element:
      the value of the string variable.
      Known issues: getvalues() still misbehaves with double-indexed arrays
      (see CFE-2504, CFE-2536)
    - The source version of CFEngine now installs binaries into
      bin folder instead of sbin folder (CFE-2448)
    - Don't error during dry run for proposed execution (CFE-2561)
    - Print verbose instead of error message when readfile() fails (CFE-2512)
    - cf-serverd: Auto configure max open files ulimit according to
      maxconnections (CFE-2575)
    - Made the max bytes parameter to file reading functions optional.
      Affects readfile(), readenvfile(), readcsv()

    Bug fixes:
    - Fix insert_lines related memory corruption (CFE-2520)
    - Prevent LMDB assertion on AIX by ensuring nested DB calls are
      not occuring during signal handler cleanup (CFE-1996)
    - Fix a bug which could cause cf-execd to believe there was
      an error when sending the email report, when there really wasn't

3.10.0:
    New features/additions:
    - All new features/additions for 3.8 and 3.9 are also included in 3.10.
    - Add: Classes body tailored for use with diff
    - New feature: Classes promise: allow classes without an expression to default to defined.
    - Support for custom ports and host names as policy hub (CFE-953)
    - Add: Definition of from_cfexecd for cf-execd initiated runs
      (CFE-2386)
    - Add < <= > >= operators to eval().
    - Add testing jUnit and TAP bundles and include them in stdlib.cf
    - New function isipinsubnet() (ENT-7949)
    - LogDebug(): implement module-based debug logging.
      Now most DEBUG messages are *not* printed even when "-d" is in use, but
      the specific debug module has to be enabled on the command line. For
      example to enable all log modules, run:
      cf-agent -d --log-modules=all
    - Add: edit_line contains_literal_string to stdlib
    - Add variablesmatching_as_data() function paralleling variablesmatching()
      (Redmine #7885)
    - Allow specifying agent maxconnections via def.json (CFE-2461)
    - Add getuserinfo() function
    - Add body agent control select_end_match_eof option. (CFE-2390)
    - Add class to enable post transfer verification during policy updates
    - Add ability to append to bundlesequnece with def.json (CFE-2460)
    - policy_server.dat now appends a newline and supports host & port

    Changes:
    - Rewrite iteration engine to avoid combinatorial explosion with nested variable expansions.
      This speeds up enormously the execution of policies that included long
      slists or JSON containers, that in the past didn't even terminate.
      Change: "cf_null" string literal was changed to not be something
      special, and it's now a string that can be used anywhere, like
      in slists or part of bundlesequence etc.
      NOTE: Old policy should be grep'ed for "cf_null" and in case such
      occurences were handled specially, they should be reworked.
      Change: "--empty-list--" is now never printed by format(),
      an empty list is now printed as "{  }".
      Change: Order of pre-evaluation was slightly changed, A new "vars" pass
      at the beginning of pre-evaluation was added. It used to be
      classes-vars, but it was changed to vars-classes-vars. As a
      result some classes or variables might be evaluated at a
      different time than before. As always try to write policy code that works no matter what the
      order of execution is.
      One way is to always *guard* the execution of functions to avoid
      bogus function results.  For example the following will avoid
      running execresult() bevore the file has been created:
      execresult("cmd /path/to/filename") if => fileexists("/path/to/filename");
      C internals: NULL Rlist is now perfectly valid, in fact it is the only
      way to denote an empty Rlist.
      C internals: Since a slist variable can be NULL, API of
      EvalContextVariableGet() changed: The way to detect if a
      variable is found, is not to check return value for NULL,
      but to check returned *type* for CF_DATA_TYPE_NONE.
      Fixed what I could find as wrong API uses. (CFE-2162)
    - Allow arbitrary service policies (CFE-2402)
    - Behaviour change: cf-execd: Do not append -Dfrom_cfexecd to exec_command .
      (CFE-2386)
    - Failsafe/Bootstrap no longer copy files starting with .git (like .gitignore) or .mailmap
      (CFE-2439)
    - Change: Enable strict transport security
    - Change: Disable http TRACE method
    - Change: Verify transfered files during policy update

    - Change: Use more restrictive unix socket perms (ENT-2705)
    - Add sys.user_data container for user starting agent.
    - Pass package promise options to underlying apt-get call (#802)
      (CFE-2468)

    - Change: Log level for keeping verbatim JSON to DEBUG (CFE-2141)
    - Change: Require network before CFEngine services (CFE-2435)
    - Behaviour change: getvalues(inexistent_var) returns an empty list.
      Restores 3.7.x and earlier behaviour. (CFE-2479)
    - Behaviour change: when used with CFEngine 3.10.0 or greater,
      bundles set_config_values() and set_line_based() are appending a
      trailing space when inserting a configuration option with empty value.
      (CFE-2466)
    - Behaviour change: getvalues() always returns a list now. Even when v is a simple
      string (i.e. not an iterable) it will return an slist with one element:
      the value of the string variable.
    - Behaviour change: readintlist() now prints an error if the
      file contains real numbers, not integers, and aborts; previously it was
      printing an info-level error message, was half-reading an integer out of
      the real, and was continuing successfully.
    - Ensure synchronous start and stop with systemctl (ENT-2841)
    - Change select_region INI_section to match end of section or end of file
      (CFE-2519)

      if there was no previous output log and the new log was fully filtered
      by email filters. (ENT-2739)
    - Allow ifelse(FALSE, $(x), "something else") to work. (CFE-2260)

    - Change: Remove executable bit from systemd units (CFE-2436)
    - cf-serverd should reload def.json when reloading policy (CFE-2406)

      "a[x][y]"). (CFE-2397)
    - When no file is provided when calling cf-promises
      with cf or json output, use promises.cf by default. This restores the
      previous behavior. (CFE-2375)
    - Fix: Services starting or stopping unnecessarily (CFE-2421)
    - Change: Split systemd units (CFE-2278)
    - EOF is  matched as an end of the region in edit_line
      promises only if 'select_end_match_eof' parameter is true. (CFE-2263)
    - Fix double logging of output_prefix, and log process name for cf-agent syslog messages.
      (CFE-2225)

    - cf-serverd: Do not close connection when file does not exist.
      (CFE-2532)
    - getvalues() now behaves correctly for old CFEngine arrays of depth 1.

3.9.0:
    New features/additions:
    - Add optional interface parameter to iprange() to match only one interface.
    - Allow '=' in symbolic modes (Redmine #7826)
    - Add: FreeBSD ports package module
    - New package module for FreeBSD pkg package manager.
    - Add support for adding/removing fifos in policy
    - Add Linux parsing of /proc/net/ data.
      - sys.inet
      - sys.inet6
      - sys.interface_data
      - Data is returned as a data container.
      - See documentation for more details. (Jira CFE-1991)
    - sys.ip2iface: new reverse mapping variable from IP to interface name
    - Namespaced classes can now be specified on the command line.
    - Namespaces can now be passed to cf-runagent -D and --remote-bundles
      (Redmine #7856)
    - Add 'cf-full' and 'json-full' to cf-promises '-p' option.
      They generate output based on the entire policy. The existing 'cf'
      already behaved this way, and it has now been changed to generate
      output only for a single file, which the existing 'json' option
      already does.
    - New language functions: processexists() and findprocesses()
      (Redmine #7633)
    - Implement new regex_replace() function. (Redmine #7346)
    - Add log rotation policy for state/classes.jsonl log. (Redmine #7951)
    - Added collect_vars utility bundle to stdlib
    - Intoduce report_class_log attribute to body agent control.
      (Redmine #7951)
    - Add standard_services service_method allowing for explicit usage
    - cf-promises --show-vars can now show JSON variables.
    - Add json_pipe mode to mapdata(), which allows piping a
      JSON container to an external program for manipulation and receiving
      JSON back. The jq tool is a good example where this mode can be
      useful. A corresponding $(def.jq) variable has also been added with
      a default path to this tool. See documentation for mapdata() for
      more information and examples. (Jira CFE-2071)
    - Behaviour change: "true" is always defined and "false" is never defined in a context expression.
    - Add: nimclient package module for AIX
      This module provides basic functionality for using nimclient as a means
      to ensure packages are either present or absent. It does not support
      listing package updates available or provide any special caching.
    - Add callstack_callers() and callstack_promisers() functions.
    - Log variable definitions in debug output. (Redmine #7137)
    - Add: Memory information to host info report (Jira CFE-1177)
    - In Mustache templates, one can now use {{#-top-}} and
      {{/-top-}} tags to iterate over the top level element in a
      container. (Redmine #6545)
    - Add network_connections() function that parses /proc/net
    - Provide new -w argument to override the workdir for testing
    - New feature: Emails sent by cf-execd can be filtered to get
      rid of emails for unwanted log messages. The attributes
      mailfilter_include and mailfilter_exclude in body executor
      control control what to include. See documentation for cf-execd for
      more information. (Jira CFE-2283)
    - Add: file_make_mustache bundle to render mustache templates
    - Add '-n' flag to cf-key to avoid host name lookups.

      for example: mergedata('[ thing, { "mykey": otherthing[123] } ]').
      thing and otherthing[123] will be resolved as variables, since
      they are unquoted. See the documentation for more details.
      (Redmine #7871)
    - Allow inline JSON to be used in the following function
      calls:
      - data_expand()

    - Add: edit_line contains_literal_string to stdlib
    - Add body agent control select_end_match_eof option. (Jira CFE-2390)

    Changes:
    - Change: classesmatching(): order of classes changed
    - Change: getindices(), getvalues(), variablesmatching(), maparray():
      order of variables returned has changed
    - Change: set_quoted_values uses bundle scoped classes
    - Change: set_config_values uses bundle scoped classes
    - Change: set_variable_values uses bundle scoped classes
    - Change: set_config_values_matching uses bundle scoped classes
    - Change: manage_variable_values_ini uses bundle scoped classes
    - Change: set_line_based should use bundle scoped classes
      (Jira CFE-1959)
    - getvalues() will now return a list also for data containers,
      and will descend recursively into the containers. (Redmine #7116)
    - Change: Improve git drop user support
    - Use new package promise as default package promise
      implementation. (Jira CFE-2332)
    - Don't follow symbolic links when copying extended attributes.
    - When a bodydefault:_ body is
      defined, it will be used by all promises of type 
      unless another body is explicitly used.
    - cf-serverd no longer appends "-I -Dcfruncommand" to
      cfruncommand, this has to be done manually in masterfiles
      body server control. (Redmine #7732)
    - eval() function arguments mode and options are now
      optional.
    - sort() function argument mode is now optional.
    - Change: returnszero() no longer outputs the output of a command.
      The output can be seen by enabling info mode (-I).
    - cfruncommand is not executed under shell. (Redmine #7409)
    - Remove: Apache CGI module
    - Change: Make maxbytes arg of readjson() and readyaml() optional
    - Classes matching agent control's abortclasses are
      now printed before exit, even if they are defined in common bundles.
      Previously the regex (in abortclasses) that matched the class was
      printed if the class was defined in a common bundle, but the class
      itself was printed if it was defined in an agent bundle. With this
      change, the defined class that caused the abort is always printed.
    - Remove: Support for email settings from augments_file (Redmine #7682)
    - Change: set_variable_values_ini uses bundle scoped classes
    - findfiles() now skips relative paths. (Redmine #7981)
    - Clients connections using non TLS protocol are rejected
      by default. . (Jira CFE-2339)
    - Change: Policy files specified in the "inputs" section of
      def.json will no longer be auto-loaded. One has to refer to the
      which are using the "inputs" field inside def.json. (Redmine #7961)
    - Change: Separate binary details from policy update (Redmine #7662)
    - Add guard for binary upgrade during bootstrap (Redmine #7861)
    - Change: Modernize pkg module and package_method
    - Remove: Userdir apache module
    - filestat(path, "linktarget") now follows non-absolute links and returns full path of target.
      This introduces a change in behaviour. Here is an example:
      $ ls -l /bin/sh
      lrwxrwxrwx 1 root root 4 Jun  4  2015 /bin/sh -> dash
      Previously the filestat function would return "dash", and would also log
      an error that the file can not be read. Now it will return "/bin/dash"
      (or the final destination if it happens that /bin/dash is also a
      symlink).
      You can still get the previous behaviour by using
      filestat(path, "linktarget_shallow"). (Redmine #7404)
    - Define (bootstrap|failsafe)_mode during update.cf when triggerd from failsafe.cf
      (Redmine #7861)
    - Behavior change: The promise string of a processes
      promise now matches just the command line of each process instead of
      the line that is output by ps. This was done to reduce fragmentation
      between platforms, since ps is a very nonstandardized tool.
      (Jira CFE-2161)
    - Allowed namespace names made more strict, to disallow
      namespaces that cannot be reached. (Redmine #7903)
    - Behavior change: When using readintlist(), readreallist()
      or readstringlist(), parsing an empty file will no longer result in a
      failed function call, but instead an empty list. Failure to open the
      file will still result in a failed function call.
    - insert_lines is no longer implicitly matching EOF as
      end of the region if 'select_end' pattern is not matched .
      (Jira CFE-2263)
    - EOF is  matched as an end of the region in edit_line
      promises only if 'select_end_match_eof' parameter is true.
      (Jira CFE-2263)

      the file containing the syntax error was specified in the def.json
      special file. (Redmine #7961)
    - Change: Policy files specified in the "inputs" section of
      def.json will no longer be auto-loaded. One has to refer to the
      $(def.augments_inputs) variable in the policy (the standard
      masterfiles policies include this by default). This only affects
      installations which are not based on the standard masterfiles, and
      which are using the "inputs" field inside def.json. (Redmine #7961)
    - Fix file descriptor leak when there are network errors.

    - Add @if feature() syntax
      @if feature work like @if minimum_version but allows distinguishing
      between features chosen at compile time.
    - Extend module protocol to create persistent classes.

    - Mustache templates: Fix {{@}} key when value is not a
      primitive. The old behavior, when iterating across a map or array of
      maps, was to abort if the key was requested with {{@}}. The new
      behavior is to always replace {{@}} with either the key name or the
      iteration position in the array. An error is printed if {{@}} is used
      outside of a Mustache iteration section.
    - Fix build with musl libc. (Redmine #7455)

      it is now logged with log-level error (was inform).
    - The JSON parser now supports unquoted strings as keys.
    - Reduce malloc() thread contention on heavily loaded
      cf-serverd, by not exiting early in the logging function, if no message
      is to be printed. (Redmine #7624) (Redmine #7624)
    - Fix a bug which caused daemons not to be restarted on
      upgrade. (Redmine #7528)

    - Fixed several bugs which prevented CFEngine from loading
      libraries from the correct location. This affected several platforms.
      (Redmine #6708)
    - Legacy package promise: Result classes are now defined if
      the package being promised is already up to date. (Redmine #7399)

      message on AIX.
    - Fix package promise not removing dependent packages. (Redmine #7424)
    - Fix: Solaris packages no longer contain duplicate library
      files, but instead symlinks to them. (Redmine #7591)
    - Fix select_class not setting class when used in common bundle with slist.
      (Redmine #7482)
    - Fix "@endif" keyword sometimes being improperly processed
      by policy parser. (Redmine #7413)
    - Fix noise from internal policy to upgrade windows agents
      (Redmine #7456)
    - cfruncommand now works if it contains spaces, with the TLS protocol.
      (Redmine #7405)
    - Fix warning "Failed to parse csv file entry" with certain very long
      commands promises. (Redmine #7400)

    - readfile() and read*list() should print an error if they fail to read file.
      (Redmine #7702)
    - Fix 'AIX_PREINSTALL_ALREADY_DONE.txt: cannot create' error
      message on AIX.
    - If there is an error saving a mustache template file
      it is now logged with log-level error (was inform).
    - Change: Clarify bootstrap/failsafe reports
    - Fixed several bugs which prevented CFEngine from loading
      libraries from the correct location. This affected several platforms.
      (Redmine #6708)
    - If file_select.file_types is set to symlink and there
      are regular files in the scanned directory, CFEngine no longer
      produces an unnecessary error message. (Redmine #6996)
    - Fix: Solaris packages no longer contain duplicate library
      files, but instead symlinks to them. (Redmine #7591)
    - cf-agent, cf-execd, cf-promises, cf-runagent and cf-serverd honor
      multiple -D, -N and -s arguments (Redmine #7191)
    - Fix "@endif" keyword sometimes being improperly processed
      by policy parser. (Redmine #7413)

    - failsafe.cf will be created when needed. (Redmine #7634)
    - Mustache templates: Fix {{@}} key when value is not a
      primitive. The old behavior, when iterating across a map or array of
      maps, was to abort if the key was requested with {{@}}. The new
      behavior is to always replace {{@}} with either the key name or the
      iteration position in the array. An error is printed if {{@}} is used
      outside of a Mustache iteration section.
    - Legacy package promise: Result classes are now defined if
      the package being promised is already up to date. (Redmine #7399)

      upgrade. (Redmine #7528)

3.7.0:
    New features:
    - New package promise implementation.
      The syntax is much simpler, to try it out, check out the syntax:
          packages:
            "mypackage"
              policy => "absent/present",

              # Optional, default taken from common control
              package_module => apt_get,

              # Optional, will only match exact version. May be
              # "latest".
              version => "32.0",

              # Optional.
              architecture => "x86_64";
    - Full systemd support for all relevant platforms
    - New classes to determine whether certain features are enabled:
      * feature_yaml
      * feature_xml
      For the official CFEngine packages, these are always enabled, but
      packages from other sources may be built without the support.
    - New readdata() support for generic data input (CSV, YAML, JSON, or auto)
    - YAML support: new readyaml() function and in readdata()
    - CSV support: new readcsv() function and in readdata()
    - New string_mustache() function
    - New data_regextract() function
    - eval() can now be called with "class" as the "mode" argument, which
      will cause it to return true ("any") if the calculated result is
      non-zero, and false ("!any") if it is zero.
    - New list_ifelse() function
    - New mapdata() function as well as JSON support in maparray().
    - filestat() function now supports "xattr" argument for extended
      attributes.
    - "ifvarclass" now has "if" as an alias, and "unless" as an inverse
      alias.
    - Ability to expand JSON variables directory in Mustache templates:
      Prefix the name with '%' for multiline expansion, '$' for compact
      expansion.
    - Ability to expand the iteration *key* in Mustache templates with @
    - Canonical JSON output: JSON output has reliably sorted keys so the
      same data structure will produce the same JSON every time.
    - New "@if minimum_version(x.x)" syntax in order to hide future language
      improvements from versions that don't understand them.
    - Compile time option (--with-statedir) to
      override the default state/ directory path.
    - Fix error messages/ handling in process signalling which no longer
      allowed any signals to fail silently
    - Also enable shortcut keyword for cf-serverd classic protocol, eg to
      simplify the bootstrap process for clients that have different
      sys.masterdir settings (Redmine #3697)
    - methods promises now accepts the bundle name in the promiser string,
      as long as it doesn't have any parameters.
    - In a services promise, if the service_method bundle is not specified,
      it defaults to the promiser string (canonified) with "service_" as a
      prefix. The bundle must be in the same namespace as the promise.
    - Inline JSON in policy files: surrounding with parsejson() is now
      optional *when creating a new data container*.
    - New data_expand() function to interpolate variables in a data container.
    - Add configurable network bandwidth limit for all outgoing
      connections ("bwlimit" attribute in "body common control") . To
      enforce it in both directions, make sure the attribute is set on both
      sides of the connection.
    - Secure bootstrap has been facilitated by use of
      "cf-agent --boostrap HUB_ADDRESS --trust-server=no"
    - Implement new TLS-relevant options (Redmine #6883):
      - body common control: tls_min_version
      - body server control: allowtlsversion
      - body common control: tls_ciphers
      - body server control: allowciphers (preexisting)

    Changes:
    - Improved output format, less verbose, and messages are grouped.
    - cf-execd: agent_expireafter default was changed to 120 minutes
      (Redmine #7113)
    - All embedded databases are now rooted in the state/ directory.
    - TLS used as default for all outgoing connections.
    - process promise now reports kept status instead of repaired if a
      signal is not sent, even if the restart_class is set. The old
      behavior was to set the repaired status whenever the process was not
      running. (Redmine#7216).
    - Bootstrapping requires keys to be generated in advance using cf-key.
    - Disable class set on reverse lookup of interfaces IP addresses.
      (Redmine #3993, Redmine #6870)
    - Define a hard class with just the OS major version on FreeBSD.
    - Abort cf-agent if OpenSSL's random number generator can't
      be seeded securely.

    - Fixed insert_lines failing to converge if preserve_block was used.
      (Redmine #7094)
    - Fixed init script failing to stop/restart daemons on openvz/lxc
      hosts. (Redmine #3394)
    - rm_rf_depth now deletes base directory as advertised. (Redmine #7009)
    - Refactored cf-agent's connection cache to properly differentiate
      hosts using all needed attributes like host and port.
      (Redmine #4646)
    - Refactored lastseen database handling to avoid inconsistencies.
      (Redmine #6660)
    - cf-key --trust-key now supports new syntax to also update the
      lastseen database, so that clients using old protocol will trust
      the server correctly.
    - Fixed a bug which sometimes caused an agent or daemon to kill or stop
      itself. (Redmine #7075, #7244)
    - Fixed a bug which made it difficult to kill CFEngine daemons,

      modifying policy supplied by the framework itself (see
      example_def.json)
    - Support for def.json class augmentation in update policy
    - Run vacuum operation on postgresql every night as a part of
      maintenance.
    - Add measure_promise_time action body to lib (3.5, 3.6, 3.7, 3.8)
    - New negative class guard cfengine_internal_disable_agent_email so
      that agent email can be easily disabled by augmenting def.json

      access_rules to controls/VER/reports.cf into bundle server
      report_access_rules
    - Re-organize cfe_internal splitting core from enterprise specific

      to be modified
    - To improve predictibility autorun bundles are activated in
      lexicographical order
    - Relocate services/file_change.cf to cfe_internal/enterprise. This
      policy is most useful for a good OOTB experience with CFEngine
      Enterprise Mission Portal.
    - Relocate service_catalogue from promsies.cf to services/main.cf. It is
      intended to be a user entry. This name change correlates with the main
      bundle being activated by default if there is no bundlesequence
      specified.
    - Reduce benchmarks sample history to 1 day.
    - Update policy no longer generates a keypair if one is not found.
      (Redmine: #7167)

      with getvalues

    Removed:
    - Diff reporting on /etc/shadow (Enterprise)

      the update policy into promsies.cf, update.cf is the entry for the
      update policy
    - _not_repaired outcome from classes_generic and scoped_classes generic
      (Redmine: # 7022)

    Fixes:
    - standard_services now restarts the service if it was not already
      running when using service_policy => restart with chkconfig (Redmine

3.6.2
    Bug fixes:
    - Don't regenerate software_packages.csv every time (Redmine #6441)
    - Improve verbose message for package_list_command
    - Fix missing log output on AIX (Redmine #6434)
    - Assorted fixes to dirname() esp on Windows (Redmine #4716)
    - Fix package manager detection

    - Don't add trailing delimiter when join()'ing lists ending with a
      null-value (Redmine #6552)
    - 9999999999 (ten 9s) or higher has been historically used as an upper
      bound in CFEngine code and policy but because of overflow on 32-bit
      platforms it caused problems with big numbers. Fixed in two ways:
      first change all existing policy uses to 999999999 (nine 9s instead
      of eleven 9s), second fix the C code to not wrap-around in case of
      overflow, but use the LONG_MAX value (Redmine #6531).
    - cf-serverd and other daemons no longer reload their configuration
      every minute if CFEngine is built with an inputs directory outside
      of the work directory (not the default). (Redmine #6551)

3.6.1
    New features:
    - Introduced Solaris and AIX support into the 3.6 series, with many associated build and
      bug fixes.

    Changes:
    - Short-circuit evaluation of classes promises if class is already set (Redmine #5241)
    - Fix to assume all non-specified return codes are failed in commands promises (Redmine #5986)
    - cf-serverd logs reconfiguration message to NOTICE (was INFO) so that it's always logged in syslog

    Bug fixes:
    - File monitoring has been completely rewritten (changes attribute in files promise), which
      eliminates many bugs, particularly regarding files that are deleted. Upgrading will keep
      all monitoring data, but downgrading again will reinitialize the DB, so all files will be
      reported as if they were new. (Redmine #2917)
    - $(this.promiser) expands in files promises for 'transformer', 'edit_template',
      'copy_from.source', 'file_select.exec_program', 'classes' and 'action' bodies
      (Redmine #1554, #1496, #3530, #1563)
    - 'body changes' notifies about disappeared files in file monitoring (Redmine #2917)
    - Fixed CFEngine template producing a zero sized file (Redmine #6088)
    - Add 0-9 A-Z _ to allowed context of module protocol (Redmine #6063)
    - Extend ps command column width and prepend zone name on Solaris
    - Fixed strftime() function on Solaris when called with certain specifiers.
    - Fixed users promise bug regarding password hashes in a NIS/NSS setup.
    - Fixed $(sys.uptime), $(sys.systime) and $(sys.sysday) in AIX. (Redmine #5148, #5206)
    - Fixed processes_select complaining about "Unacceptable model uncertainty examining processes" (Redmine #6337)
    - ps command for linux has been changed to cope with big rss values (Redmine #6337)
    - Address ps -axo shift on FreeBSD 10 and later (Redmine #5667)
    - methods and services promises respect action_policy => "warn" (Redmine #5924)
    - LMDB should no longer deadlock if an agent is killed on the hub while holding the DB lock.
      Note that the change only affects binary packages shipped by CFEngine, since the upstream
      LMDB project has not yet integrated the change. (Redmine #6013)

3.6.0

    Changes:
    - Changes to logging output
      - Add process name and pid in syslog message (GitHub #789)
      - cf-serverd logging levels are now more standardised:
        - INFO logs only failures
        - VERBOSE logs successful requests as well
        - DEBUG logs actual protocol traffic.
      - cf-serverd now logs the relevant client IP address on
        each message.
      - Logging contexts to local database (cf_classes.tcdb) has been deprecated.
      - 'usebundle' promisees are logged for all the bundle promises
      - output from 'reports' promises has nothing prefixed except 'R: '
      - a log line with stack path is generated when the promise type evaluated changes
    - LMDB (symas.com/mdb) is the default database for local data storage : use version 0.9.9 or later
      cf-agent --self-diagnostics (-x) is only implemented for TCDB, not for LMDB
    - port argument in readtcp() and selectservers() may be a
      service name (e.g. "http", "pop3").
    - Enable source file in agent copy_from promises to be a relative path.
      - file "changes" reporting now reports with log level "notice", instead of "error".
    - process_results default to AND'ing of set attributes if not specified (Redmine #3224)
    - interface is now canonified in sys.hardware_mac[interface] to align with
      sys.ipv4[interface] (Redmine #3418)
    - cf-promises no longer errors on missing bodies when run without --full-check (-c)
    - Linux flavor "SUSE" now correctly spelled with all uppercase in variables and class names
      (Redmine #3734).  The "suse" lowercase version is also provided for convenience (Redmine #5417).
    - $(this.promise_filename) and $(..._dirname) variables are now absolute paths. (Redmine #3839)
    - Including the same file multiple times in 'body control inputs' is not an error
    - portnumber in body copy_from now supports service names like
      "cfengine", "pop3" etc, check /etc/services for more.
    - The failsafe.cf policy, run on bootstrap and in some other
      unusual cases, has been extracted from C code into libpromises/failsafe.cf
    - masterfiles
      - cf_promises_validated is now in JSON format
      - timestamp key is timestamp (sec since unix epoch) of last time validated
      - the masterfiles now come from https://github.com/cfengine/masterfiles and are
        not in the core repository
    - cf-serverd calls cf-agent with -Dcfruncommand when executing cf-runagent requests
    - Mark as removed: promise_notkept_log_include, promise_notkept_log_exclude, promise_repaired_log_include,
      promise_repaired_log_exclude, classes_include, classes_exclude, variables_include,
      variables_exclude attributes from report_data_select body (syntax is valid but not functional).
      They have been replaced by the following attributes: promise_handle_include,
      promise_handle_exclude, metatags_include, metatags_exclude.

    New features:
    - New promise type "users" for managing local user accounts.
    - TLS authentication and fully encrypted network protocol.
      Additions specific to the new type of connections:
      - New attribute "allowlegacyconnects" in body server control,
        which enables serving policy via non-latest CFEngine protocol,
        to the given list of hosts. If the option is absent, it
        defaults to allow all hosts. To refuse non-TLS connections,
        specify an empty list.
      - New attribute "protocol_version" in body copy_from, and body
        common control, which defines the preferred protocol for
        outgoing connections.. Allowed values at the moment: "0" or
        "undefined", "classic" or "1", "latest" or "2". By leaving the
        copy_from option as undefined the common control option is
        used, and if both are undefined then classic protocol is used
        by default.
      - The new networking protocol uses TLS for authentication,
        after which all dialog is encrypted within the established
        TLS session.  cf-serverd is still able to speak the legacy
        protocol with old agents.
      - The 'skipverify' option in 'body server control' is
        deprecated and only left for compatibility; it does
        nothing
      - cf-serverd does not hang up the connection if some request
        fails, so that the client can add more requests.
      - For the connections using the new protocol, all of the
        paths in bundle server access_rules now differentiate
        between a directory and a file using the trailing
        slash. If the path exists then this is auto-detected and
        trailing slash appended automatically. You have to append
        a trailing slash manually to an inexistent or symbolic
        path (e.g. "/path/to/$(connection.ip)/") to force
        recursive access.
    - New in 'access' promises for 'bundle server access_rules'
      - Attributes "admit_ips", "admit_hostnames", "admit_keys",
        "deny_ips", "deny_hostnames", "deny_keys"
      - "admit_keys" and "deny_keys" add the new functionality
        of controlling access according to host identity,
        regardless of the connecting IP.
      - For these new attributes, regular expressions
        are not allowed, only CIDR notation for "admit/deny_ips", exact
        "SHA=..." strings for "admit/deny_keys", and exact hostnames
        (e.g. "cfengine.com") or subdomains (starting with dot,
        e.g. ".cfengine.com") for "admit/deny"_hostnames. Same rules
        apply to 'deny_*' attributes.
      - These new constraints and the paths in access_rules, can contain
        special variables "$(connection.ip)", "$(connection.hostname)",
        "$(connection.key)", which are expanded dynamically for every
        received connection.
      - For connections using the new protocol, "admit" and "deny"
        constraints in bundle server access_rules are being phased
        out, preferred attributes are now "admit_ips", "deny_ips",
        "admit_hostnames", "deny_hostnames", "admit_keys",
        "deny_keys".
      - New "shortcut" attribute in bundle server access_rules used to
        dynamically expand non-absolute request paths.
    - masterfiles
      - standard library split: lib/3.5 (compatibility) and lib/3.6 (mainline)
      - many standard library bundles and bodies, especially packages- and file-related,
        were revised and fixed
      - supports both Community and Enterprise
      - new 'inventory/' structure to provide OS, dmidecode, LSB, etc. system inventory
        (configured mainly in def.cf)
      - cf_promises_release_id contains the policy release ID which is the GIT HEAD SHA
        if available or hash of tree
      - a bunch'o'bundles to make starting with CFEngine easier:
      - file-related: file_mustache, file_mustache_jsonstring, file_tidy, dir_sync, file_copy,
        file_link, file_hardlink, file_empty, file_make
      - packages-related: package_absent, package_present, package_latest,
        package_specific_present, package_specific_absent, package_specific_latest, package_specific
      - XML-related: xml_insert_tree_nopath, xml_insert_tree, xml_set_value, xml_set_attribute
      - VCS-related: git_init, git_add, git_checkout, git_checkout_new_branch,
        git_clean, git_stash, git_stash_and_clean, git_commit, git
      - process-related: process_kill
      - other: cmerge, url_ping, logrotate, prunedir
    - New command line options for agent binaries
      - New options to cf-promises
      - '--show-classes' and '--show-vars'
      - '--eval-functions' controls whether cf-promises should evaluate functions
      - Colorized output for agent binaries with command line option '--color'
        (auto-enabled if you set CFENGINE_COLOR=1)
    - New language features
      - New variable type 'data' for handling of structured data (ie JSON),
        including supporting functions:
        - 'data_readstringarray' - read a delimited file into a data map
        - 'data_readstringarrayidx' - read a delimited file into a data array

        - pass a data container to a bundle with the @(container) notation
        - the module protocol accepts JSON for data containers with the '%' sigil
        - Tagging of classes and variables allows annotating of language construct with
          meta data; supporting functionality:
        - The module protocol in 'commands' promises has been extended to allow setting
          of tags of created variables and classes, and the context of created variables
        - 'getclassmetatags' - returns list of meta tags for a class
        - 'getvariablemetatags' - returns list of meta tags for a variable
        - 'body file control' has an 'inputs' attribute to include library files and other
          dependencies

    - New attributes in existing promise types and bodies
      - New option 'preserve_all_lines' for insert_type in insert_lines promises
      - Caching of expensive system functions to avoid multiple executions of
        execresult() etc, can be controlled via cache_system_functions attribute in
        body common control
      - New option 'mailsubject' in body executor control allows defining the subject
        in emails sent by CFEngine
      - Support for Mustache templates in 'files' promises; use 'template_method' and

3.5.3
    Changes:
    - Improved security checks of symlink ownership. A symlink created by a user pointing
      to resources owned by a different user will no longer be followed.
    - Changed the way package versions are compared in package promises. (Redmine #3314)
      In previous versions the comparison was inconsistent. This has been fixed, but may
      also lead to behavior changes in certain cases. In CFEngine 3.5.3, the comparison
      works as follows:
          
      For instance:
        apache-2.2.31              ">="            "2.2.0"
      will result in the package being installed.

3.5.1

    Changes:
    - File changes are logged with log level Notice, not Error
    - The CFEngine Standard Library in masterfiles/libraries is now split into
      promise-type specific policy files, and lives in a version-specific directory.
      This should have no impact on current code, but allows more granular include of
      needed stdlib elements (Redmine #3044)

      - nth
      - sublist
      - uniq
      - filter
      - classesmatching
      - strftime
      - filestat
      - ifelse
      - maparray
      - format
    - cf-promises flag --parse-tree is replaced by --policy-output-format=, requiring the
      user to specify the output format (none, cf, json)
    - cf-promises allows partial check of policy (without body common control) without integrity check;
      --full-check enforces integrity check
    - Agent binaries support JSON input format (.json file as generated by cf-promises)
    - cf-key: new options --trust-key/-t and --print-digest/-p
    - Class "failsafe_fallback" is defined in failsafe.cf when main policy contains errors and
      failsafe is run because of this
    - Add scope attribute for body classes (Redmine #2013)
    - Better diagnostics of parsing errors
    - Error messages from parser now show the context of error
    - New cf-agent option: --self-diagnostics
    - New output format, and --legacy-output
    - Warnings for cf-promises.
    - Enable zeroconf-discovery of policy hubs for automatic bootstrapping
      if Avahi is present
    - Support for sys.cpus on more platforms than Linux & HPUX

    Changes:
    - Parser no longer allows ',' after promiser or promisee. must be either ';' or lval
    - Make parser output in GCC compatible format the only supported format
      (remove --gcc-brief-format flag)

    - Silence license warnings in Enterprise Free25 installations
    - action_policy => "warn" causes not_kept classes to be set on promise needing repair.
    - Command line option version (-V) now prints a shorter parsable version without graphic
    - Implicit execution of server and common bundles taking arguments is skipped in cf-serverd.
    - WARNING: option --policy-server removed, require option to --bootstrap instead
    - process promises don't log if processes are out of range unless you
      run in verbose mode
    - reports promises are now allowed in any context (Redmine #2005)
    - cf-report has been removed
    - cf-execd: --once implies --no-fork
    - Version info removed from mail subject in the emails sent by cf-execd.
      The subject will only contain "[fqname/ipaddress]" instead of "communnity/nova [fqname/ipaddress]"
      Please change your email filters accordingly if necessary.
    - "outputs" promise type is retired. Their semantics was not clear, and the functionality
      is better suited for control body setting, not a promise.
    - Tokyo Cabinet databases are now automatically checked for
      correctness during opening. It should prevent a number of issues
      with corrupted TC databases causing binaries to hang.
    - Improved ACL handling on Windows, which led to some syntax changes. We now consistently
      use the term "default" to describe ACLs that can be inherited by child objects. These
      keywords have received new names:
        acl_directory_inherit -> acl_default
         specify_inherit_aces -> specify_default_aces
      The old keywords are deprecated, but still valid. In addition, a new keyword
      "acl_inherit" controls inheritance behavior on Windows. This feature does not exist on
      Unix platforms. (Redmine #1832)
    - Networking code is moved from libpromises to its own library,
      libcfnet. Work has begun on making the API more sane and thread-safe.
      Lots of legacy code was removed.
    - Add getaddrinfo() replacement in libcompat (borrowed from PostgreSQL).
    - Replace old deprecated and non thread-safe resolver calls with
      getaddrinfo() and getnameinfo().
    - Hostname2IPString(), IPString2Hostname() are now thread-safe, and are
      returning error when resolution fails.
    - Running cf-execd --once now implies --no-fork, and also does not wait
      for splaytime to pass.
    - execresult(), returnszero() and commands promises no longer requires the first word
      word to be an absolute path when using the shell. (Part of Redmine #2143)
    - commands promises useshell attribute now accepts "noshell" and "useshell" values. Boolean
      values are accepted but deprecated. (Part of Redmine #2143)
    - returnszero() now correctly sets the class name in this scenario  (Part of
      Redmine #2143):
        classes:
          "commandfailed" not => returnszero("/bin/nosuchcommand", "noshell");

    Bugfixes:
    - Bundles are allowed to be empty (Redmine #2411)
    - Fixed '.' and '-' not being accepted by a commands module. (Redmine #2384)

    - Allocate memory dynamically to avoid out-of-buffer or out-of-hash
      situations
    - Fix edit_xml update of existing attributes  (Redmine #2034)
    - Use failsafe policy from compile-time specified workdir (Redmine #1991)

    - Do not wait for splaytime when executing only once
    - Disable xml editing functionality when libxml2 doesn't provide necessary APIs (Redmine #1937)
    - Out-of-tree builds should work again, fixed a bunch of related bugs.
    - Fixed race condition in file editing. (Redmine #2545)
    - Fixed memory leak in cf-serverd and others (Redmine #1758)

    - Fix potential segmentation fault when trimming network socket data (GitHub #233)
    - Fix potential segmentation fault when address-lookups in lastseen db failed (GitHub #233)
    - Execute background promise serially when max_children was reached, rather
      than skipping them (GitHub #233)
    - Fix segmentation fault in cf-promises when invoked with --reports (Redmine #1931)
    - Fix compilation with Sun Studio 12 (Redmine #1901)
    - Silence type-pun warning when building on HP-UX (GitHub #287)

3.4.1: (Bugfix and stability release)

    New feature/behavior:
    - cf-execd terminates agent processes that are not responsive
      for a configurable amount of time (see agent_expireafter in body
      executor control), defaulting to 1 week

    Bugfixes:
    - Fix regression of classmatch() failing with hard classes (Redmine #1834)

      NOTE: code that uses select_xpath_region needs to be changed to
      select_xpath
    - edit_xml: make sure that text-modification functions don't overwrite
      child nodes
    - edit_xml: improve error logging

3.4.0

    New features:
    - Added rpmvercmp utility to compare versions of RPM packages for
      accurate sorting of RPM packages for packages promises.
    - Implement network timeout on server side to avoid keeping stale
      connections for hours.
    - XML editing capabilities. See the documentation for edit_xml
      body. Note the new dependency: libxml2.
    - Implement inheritance of local classes by bundles called using
      "usebundle". By default classes are not inherited. See the
      examples/unit_inherit.cf for an example.
    - Moved from Nova/Enterprise:
      - POSIX ACL support,
      - "outputs" promise type,
      - remote syslog support.
    - packages_default_arch_command hook in packages promises, to
      specify default architecture of the packages on the system.
    - packages_version_less_command / packages_version_equal_command hooks
      in packages promises, to specify external command for native package
      manager versions comparison
    - agent_expireafter in body executor control allows you to set a
      timeout on all cf-agent runs, to enforce a threshold on the
      number of concurrent agents
    - Running in Solaris zone is now detected and classes "zone" and
      "zone_" are created in this case.
    - VirtualBox support added to guest_environment promises.
    - guest_environment promises are supported under OS X.
    - The "depends_on" attribute is now active, for the partal ordering
      of promises. If a promise depends on another (referred by handle)
      it will only be considered if the depends_on list is either kept
      or repaired already.

      ** WARNING: When upgrading, make sure that any existing use
      of depends_on does not make some promises being
      unintentionally ignored. This can happen if you are
      currently referring to non-existent or never-run handles
      in depends_on attributes.
    - methods return values, initial implementation
    - New format for cf-key -s, includes timestamp of last connection
    - cf-promises --parse-tree option to parse policy file and dump it
      in JSON format
    - Namespaces support for bundles and bodies. See the
      examples/unit_namespace*.cf for the usage.
    - Default arguments for bundles. See the examples/unit_defaults.cf
    - Metadata promise type. See the examples/unit_meta.cf

    New semantics:
    - Methods promises now return the status of promises
      kept within them. If any promise was not kept, the method is not
      kept, else if any promise is repaired, the method was repaired
      else it was kept.
    - Remote variable access in namespaces by $(namespace:bundle.variable)

    Changed functionality:
    - cf-execd -F switch no longer implies 'run once'. New -O/--once
      option is added to achieve this behaviour. This makes cf-execd
      easier to run from systemd, launchd and other supervision
      systems.

    Misc:
    - Support for the following outdated platforms and corresponding
      classes has been removed. De facto those platforms were
      unsupported for a long time, as CFEngine codebase uses C99
      language features unavailable on old platforms:

       - SunOS 3.x (sun3)
       - SunOS 4.x (sun4)
       - Ultrix (ultrix)
       - DEC OSF/1 AXP (osf)
       - Digital UNIX (digital)
       - Sony NEWS (newsos)
       - 4.3BSD (bsd4_3)
       - IRIX (irix, irix4, irix64)
       - IBM Academic Operating System (aos)
       - BSD/OS / BSDi / BSD/386 (bsdos)
       - NeXTSTEP (nextstep)
       - GNU Hurd (gnu)
       - NEC UX/4800 (ux4800)
    - (Old news) Since 3.3.0 the layout of CFEngine Community packages
      has changed slightly.

      cf-* binaries have been moved to /var/cfengine/bin, due to the
      following reasons:
      - cf-* binaries are linked to libraries installed to
        /var/cfengine/lib, so placing binaries in /usr/local/sbin does not
        increase reliability of the CFEngine,
      - keeping whole CFEngine under single prefix (/var/cfengine)
        makes packaging simpler,
      - it matches the layout of CFEngine Enterprise packages.

      Please adjust your policies (the recommended ways to deal with
      the move are either to adjust $PATH to include /var/cfengine or to
      create symlinks in /usr/local/sbin in case you are relying on
      binaries to be available in $PATH).
    - Workdir location is properly changed if --prefix or --enable-fhs
      options are supplied to configure (Mantis #1195).
    - Added check for broken libmysqlclient implementations (Mantis #1217).
    - Standard library is updated from COPBL repository.
    - cf-know is no longer built in Community releases. The only
      functionality useful in Community, namely the reference manual
      generation, is provided by new compile-time cf-gendoc tool.
    - Filename (for storing filechanges) changed
      from file_change.log -> file_changes.log (in /var/cfengine/state)

      New format for storing file changes introduced:
      [timestamp,filename,,Message]

      N = New file found
      C = Content Changed
      S = Stats changed
      R = File removed
    - Acceptance test suite passes on Mac OS X.
    - Changed some port numbers to replace old services with imap(s)
    - archlinux hard class on Arch Linux.
    - Detect BSD Make and automatically switch to GNU Make during build.

    Bugfixes:
    - cfruncommand for cf-execd is an arbitrary shell command now (Mantis #1268).
    - Fixed broken "daily" splayclasses (Mantis #1307).
    - Allow filenames up to 4096 bytes in network transfers (Redmine #1199).
    - Fix stale state preserved during cf-serverd reload (Redmine #1487).
    - Free disk space calculation is fixed (Mantis #1120).
    - Numerous portability bugfixes (especially OpenBSD, Solaris, AIX-related).
    - Compatibility fixes for AIX, HP-UX, Solaris (Mantis #1185, Mantis #1177, Mantis #1109).
    - Fixed broken socklen_t configure check under OpenBSD (Mantis #1168).
    - Fixed hang in cf-promises under OpenBSD (Mantis #1113).
    - Fixed endless loop in evaluating "$()" construct (Mantis #1023).
    - Fixed check for old PCRE versions (Mantis #1262).
    - Fixed insertion of multi-line blocks at the start of file (Mantis #809).
    - Fixed numerous memory leaks.
    - Fixes for metadata that were not resolvable
    - Fixes for namespaces that would not support metadata and variable expansion
    - Point-to-point network interfaces are detected and reported by CFEngine (Mantis #1246)
    - Partial non-GNU userspace support in acceptance testsuite (Mantis #1255)

    Full list of issues fixed is available on
    https://cfengine.com/bugtracker/changelog_page.php (old bug tracker)
    and https://cfengine.com/dev/projects/core/versions/34 (new bug tracker)

3.3.9: (Bugfix and stability release)

    Bugfixes:
    - Do not lose hard classes in cf-serverd during policy reload
      (Mantis #1218).
    - Implement receive network timeout in cf-serverd. Prevents
      overloading cf-serverd with stale connections.

3.3.8: (Bugfix and stability release)

    Versions 3.3.6, 3.3.7 were internal and weren't released.

    Bugfixes:
    - Propery set sys.domain variable if hostname is fully-qualified.
    - Fixed several small memory leaks.
    - Make network timeout for network reads configurable. Previously
      it was hardcoded to be 30 seconds, which was not enough for
      cf-runagent invoking cf-agent on big policies (Mantis #1028).

3.3.5: (Bugfix and stability release)

    Bugfixes:
    - Fixed cf-execd memory leak on hosts with cf-monitord running.
    - Robustify against wrongly-sized entires in embedded databases.

    Standard library:
    - Bugfixes from upstream COPBL repository.
    - standard_services bundle from upstream COPBL repository.


3.3.4: (Bugfix and stability release)

    Evaluation of policies:
    - Fix wrong classes set after installation of several packages
      using packages promises (Mantis #829).
    - Fix segfault using edit_template on existing file (Mantis #1155).

    Misc:
    - Fix memory leak during re-read of network interfaces'
      information in cf-execd/cf-serverd.

3.3.3: (Bugfix and stability release)

    Evaluation of policies:
    - Zero-length files are valid for readfile() and similar functions
      (Mantis #1136).
    - Unchoke agent in case it encounters symlinks in form ./foo
      (Similar to Mantis #1117).

    Misc:
    - Fix generation of reference manual on machines with umask more
      relaxed than 022.
    - Use statvfs(3) on OpenBSD to obtain filesystem information
      (Mantis #1135).

3.3.2: (Bugfix and stability release)

    Evaluation of policies:
    - Do not segfault if file copy was interrupted due to network
      connectivity or server going away (Mantis #1089).
    - Do not segfault if log_failed attribute is present in body, but
      log_kept is not (Mantis #1107).
    - Do not mangle relative paths in symlinks during file copy
      Previously symlink a -> b was mangled to a -> ./b.
      (Mantis #1117)
    - Properly compare 1.0 and 1.0.1 in packages promises. Previously
      only versions with equal amount of "segments" were comparable
      (Mantis #890, #1066).

    Base policy:
    - Properly set permissions on files for /var/cfengine/lib on HP-UX
      (Mantis #1114).
    - Standard library (cfengine_stdlib.cf) is synced with COPBL
      repository.

    Misc:
    - Do not create huge file in case corrupted TokyoCabinet database
      is detected (Mantis #1106).
    - Fix file descriptor leak on error paths, may have caused crashes
      of cf-execd and cf-serverd (Issue #1096).
    - Fix intermittent segfault in cf-execd (Mantis #1116).
    - Impose an upper limit on amount of listening sockets reported by
      cf-monitord. Huge amounts of listening sockets caused cf-agent to
      segfault on next run (Mantis #1098).
    - Add missing function prototypes caused errors during compilation
      on HP-UX (Mantis #1109).
    - Fix compilation on Solaris 11 (Mantis #1091).

3.3.1: (Bugfix and stability release)

    Evaluation of policies:
    - Do not cut off name of bundle in variables interpolation (Mantis #975).
    - Do not segfault in function evaluation guarded by ifvaclass clause (Mantis #1084, #864).
    - Do not segfault if "classes" promise does not declare any value to be evaluated (Mantis #1074).
    - Do not segfault in database promises if there is no
      database_operation provided (Mantis #1046).

    Built-in functions:
    - Fix countclassesmatching() function which was misbehaving trying
      to match classes starting with alphanumeric symbol (Mantis #1073).
    - Fix diskfree() to return kilobytes, as described in documentation (Mantis #980, #955).
    - Fix hostsseen() function to avoid treating all hosts as not
      being seen since 1970 (Mantis #886).
    - Do not output misleading error message if readtcp() is unable to connect (Mantis #1085).

    Command-line interface:
    - -d option previously reqired an argument, though help message disagreed (Mantis #1053).
    - Disable --parse-tree option, not ready for the release (Mantis #1063).
    - Acept -h as a --help option.
    - Ensure that cf-execd might be started right after being shut down.

    Misc:
    - Plug file descriptor leak after failed file copy (Mantis #990).
    - Fix unsafe admit rules in default promises.cf (Mantis #1040).
    - Fix splaytime to match documentation: it is specified in minutes, not seconds (Mantis #1099).

    Packaging:
    - Fix owner/group of initscript and profile.d snippet in RPM builds (Mantis #1061, #1058).
    - Fix location of libvirt socket CFEngine uses to connect to libvirtd (Mantis #1072).
    - Install CoreBase to /var/cfengine/masterfiles during installation (Mantis #1075).
    - Do not leave old cf-twin around after upgrade (Mantis #1068)
    - Do not leave rcS.d symlinks after purging .deb package (Mantis #1092).

3.3.0

    New promise types:
    - Guest environments promises, which allow to manipulate virtual
      machines using libvirt.
    - Database promises, which allow to maintain schema of MySQL and
      PostgreSQL databases. Database promises are in "technical preview"
      status: this promise type is subject to change in future.
    - Services promises for Unix, allows abstraction of details
      on managing any service

    New built-in functions:
    - dirname() to complement lastnode()
    - lsdir()
    - maplist() to apply functions over lists

    New features:
    - Allow defining arrays from modules.
    - Allow both process_stop' and signals' constraints in
      processes' promises at the same time.
    - cf-promises --gcc-brief-format option to output warnings and
      errors in gcc-compatible syntax which to ease use "go to next
      error" feature of text editors.
    - Iteration over lists is now allowed for qualified (non-local) lists.

    New built-in variables and classes (Linux):
    - Number of CPUs: $(sys.cpus), 1_cpu, 2_cpus etc

    New built-in variables and classes (Unices):
    - $(sys.last_policy_update) - timestamp when last policy change was seen by host
    - $(sys.hardware_addresses) - list of MAC adresses
    - $(sys.ip_addresses) - list of IP addresses
    - $(sys.interfaces) - list of network interfaces
    - $(sys.hardware_mac[$iface]) - MAC address for network interface
    - mac_:: - discovered MAC addresses

    Changes:
    - Major cleanup of database handling code. Should radically decrease
      amount of database issues experienced under heavy load.

      *WARNING*: Berkeley DB and SQLite backends are *removed*, use
      Tokyo Cabinet or QDBM instead. Both Tokyo Cabinet and QDBM are
      faster than Berkeley DB in typical CFEngine workloads.

      Tokyo Cabinet requires C99 environment, so it should be
      available on every contemporary operating system.

      For the older systems QDBM, which relies only on C89, is a
      better replacement, and deemed to be as portable, as Berkeley DB.
    - Change of lastseen database schema. Should radically decrease
      I/O contention on lasteen database.
    - Automatic reload of policies by cf-execd.
    - Documentation is generated during build, PDF and HTML files are
      retired from repository.
    - Rarely used feature retired: peer connectivity intermittency calculation.
    - Memory and CPU usage improvements.
    - Testsuite now uses 'make check' convention and does not need root
      privileges anymore.
    - cf_promises_validated now filled with timestamp, allows digest-copy
      for policy instead of mtime copy which is safer when clocks are unsynchronised
    - The bundled failsafe.cf policy now has trustkey=false to avoid IP spoofing
      attacks in default policy
    - See the full list of bugfixes at
      https://cfengine.com/bugtracker/changelog_page.php

3.2.4: (Bugfix and stability release)
    - Fixed failure in network transfer in case of misbehaving peer
    - A few tiny memory leaks on error paths fixed

3.2.2: (Bugfix and stability release)
    - Enabled compilation in "large files" mode under AIX
    - Alleviated problem with broken file transfers over unstable
      internet links.

    - Fixed compilation under HP-UX and Solaris
    - Enabled compilation using HP ANSI C compiler
    - Full list of issues fixed is available on
    - https://cfengine.com/bugtracker/changelog_page.php

3.2.0:
    New bootstrap method with single-command bootstrapping:
    - cf-agent --bootstrap --policy-server 123.456.789.123
    - Associated policy template files are added, partially maintained
      by CFEngine
    - Bug fixes for file-editing, package versioning, and embedded
      database corruption (We recommend using TokyoCabinet instead of
      BerkeleyDB if building from source).
    - Improved upgrade path for Nova.
    - Patches for improved run-agent concurrency
    - Reorganization of documentation and community resources
    - 100% on regression test suite on 3 operating systems
      (Ubuntu, Debian, SuSE on x86-64 hardware)
    - Support for multiple release environments
    - package_policy update and addupdate now check if user-supplied
      version is larger than currently installed - updates only if so
    - Help text of cf-report -r corrected - a list of key hashes is
      required, not ip addresses.
    - New Emacs mode for CFEngine policy files (thanks to Ted Zlatanov!)
    - Warnings are on edit_line changes can now give greater degree of information
      without spamming promise logs
    - Class expressions parser accepts '||' as an alias for '|' again.

      packages.
    - New option cf-key -r to remove host key by IP or hostname.

    - Improve robustness of multi-threaded code, in particular fix
      problems with spurious access denials in server and losing of
      authentication rules after policy reload.
    - cf-promises accepts option -b matching cf-agent, which causes it
      to do not complain about missing bundlesequence.
    - New functions and(), not(), or() and concat() to ease use of
      ifvarclass() clause.
    - Full list of issues fixed is available on
      https://cfengine.com/bugtracker/changelog_page.php

3.1.5:
    - New class parser, '||' is no longer allowed in expressions (use '|').
    - Class setting in the promise types insert_lines, delete_lines,
      replace_patterns, field_edits, vars, classes is restored.
    - suspiciousnames implemented.
    - New function getvalues().
    - New functions parse{read,int,string}array to match read{read,int,string}array.
    - Testsuite added to check for core functionality.
    - Syslog prefix is fixed to say 'cf3' instead of 'community'.

3.1.4: (Bugfix and stability release)
    - Some urgent patches to 3.1.3.
    - Class validation parse bug fixed.
    - Global zone handling error for solaris fixed.
    - Package architectures handled correctly (bug #456).
    - Reading and writing of key name "root-.pub" eliminated (bug #442, #453).
    - cf-serverd crash because of race condition on SERVER_KEYSEEN fixed.
    - Lock purging to avoid remnant complexity explosion (bug #430).
    - Some copyright notices added that got lost.

3.1.3: (Stability release)
    - Major memory leaks in cf-monitord, cf-execd, cf-serverd fixed (bug #427).
      The daemons now show no growth even with very complex policies.
    - cf-serverd crash due to race condition in DeleteScope() fixed (bug #406).
    - Added 30 second timeout on recv() on Linux.
    - package_noverify_returncode implemented (bug #256).
    - A flexible mechanism for setting classes based on return codes of
      commands has been introduced. Allows for setting promise kept,
      repaired or failed based on any return codes. This is currently
      implemented for commands-promises, package-manager commands and
      transformer in files. In classes body, see attributes
      kept_returncodes, repaired_returncodes, failed_returncodes (bug
      #248, #329).
    - New function ip2host - reverse DNS lookup (bug #146).

3.1.2: (Scalability/efficiency release)
    - Big efficiency improvements by caching output from
      cf-promises. Can also be used for much more efficient policy
      deployment (only pull if changed).
    - Caching state of ps command for greater efficiency. Reloaded for each bundle.
    - Index class lookup improves efficiency of class evaluation for huge configurations.
    - Fixed issue where certain promiser strings got corrupted.
    - Minor memory access issues fixed.
    - Iterator bug introduced in 3.1.0 fixed

3.1.1: (Bugfix release)
    - Memory leaks in server tracked down and fixed.
    - List expansion bug (one list items not executed) fixed.
    - Security issue introduced by change of runcommand shell policy fixed. If users defined a runcommand for cf-runagent/cf-serverd communication, possible to execute commands.
    - cf-key -s command for showing key hash/IP address identity pairs

3.1.0:
    - Change in storage of public keys. Cfengine now hashes the public key and uses this
      as the keyname. Keys will be converted automatically.
    - The old dynamic addresses lists are deprecated.
      Caching of dns and key information for greater server speed.
      Change in last-seen format reflects the public key usage.
    - New package policy addupdate - installs package if not there and
      updates it otherwise.
    - Support for package_changes => "bulk" in file repository as well.
    - New special function readstringarrayidx, similar to readstringarray,
      but uses integer indices. Very useful if first row elements are
      not good identifiers (e.g. contains spaces, non-unique, etc.).
    - Change two log formats to use time() instead of date()
      - filechanges
      - total compliance
    - Change from using md5 to sha256 as default digest for commercial version,
      community retains md5 for compat.
    - Commands not returning 0 in commands-promises are flagged
      as repair_failed.
    - Adjustable timeout on connect(). Defaults to 10 seconds, adjustable
      with default_timeout in agent control.
    - Redesign of the knowledge map infrastructure.
    - Now possible to use variables to call methods, e.g
          methods:
            "name $(list)" usebundle => $(list)("abc");
      See reference manual notes
    - Changes to normal ordering to optimize execution.
    - Increased stability by always initializing Attribute and Promise
      structures.
    - When running cf-promises in dry-run mode (-n), the user does not need
      to put binaries in WORKDIR/bin. For example, non-privileged users can verify root
      policies.
    - Source control revision added in version string if run in verbose mode
      (e.g. "cf-promises -vV"). This needs some refining, uses revision of a header now.
    - New semantics in return values of list functions. Null values are now allowed
      and there is no iteration over empty lists. The value "cf_null" is reserved for
      use as a null iterator.

3.0.5p1:
    - Showing paths allowed/denied access to when cf-serverd is run in verbose mode.
    - Bug in server fixed for dynamic addresses.
    - File handle closure bugfix - too many open databases.

    - Various build enahncements.
    - Package_list_update called only once per manager, and fixed crash.
    - Version number bug in packages.

3.0.5:
    - Encryption problems fixed - client key buffer was uninitialized.
    - Classes-promisers are now automatically canonified when class
      strings are defined, to simplifying the use of variables in classes.
    - New scalars sys.cf_version and sys.nova_version that hold Cfengine version information.
    - Attribute package_delete_convention added, to allow customizable
      package name in delete command during update.
    - package_list_update_ifelapsed limit added.
    - Private variable $(firstrepo) is available in package_name_convention
      and package_delete_convention in order to expand the full path to
      a package, which is required by some managers.
    - Some of the threading code is rewritten and made more robust. This includes
      synchronizing access to the lastseen database from the server.
    - Bad initialization of BSD flags fixed
    - Multiple variable expansion issues in control fixed for server and agent
    - Allow ignore_missing_bundles to affect methods: bundles too
    - Run agent trust dialogue fixed
    - Bug in CPU monitoring, increasing time scale caused linear decay
      of CPU measurement.
    - Bug in Setuid log storage, fix.
    - Hooks added for new Nova virtualization promises.
    - Multithreading mutex failed to collide during cfservd leading to dropped authentication under heavy load.


3.0.4:
    - Class cancellation in promises to create better class feedback,
      allows emulation of switch/case semantics etc
    - Value of SA measurement promises
    - Special function getenv() which returns the contents of an
      environment variable (on all platforms).
    - New function translatepath for generic Windows
    - New function escape() to escape literals as regular expressions (like SQL)
    - New function host2ip for caching IP address lookup
    - New function regextract for setting variables with backreferences
    - New variables for the components $(sys.cf_agent), $(sys.cf_know) etc
      pointing to the binaries.
    - More robust integrated database implementation; closing all
      handles when receiving signals, self-healing on corruption.
    - Package installation on localhost without a manager like yum completed,
      multiple repositories searched, and universal methods.
    - Numerous bugfixes


3.0.3:
    - sha256 .. new hashes in openssl included in syntax tree.
    - End of line autocropping in readfile (hopefully intelligent)
    - hashmatch function incorrectly implemented - old debugging code left behind. Fix.
    - sys.crontab variable
    - Unknown user is now interpretated as "same user", so that we give CFEngine a chance to
      fix
    - Unregistered addresses no longer report "(Non registered IP)", but return as the address
      itself when doing reverse lookups.

    - Added self upgrade support for SUSE (ENT-7446)
    - Added separate classes for controlling autorun inputs and bundles
      The class services_autorun continues to enable both automatic inclusion of .cf
      files in services/autorun and the running of bundles tagged with autorun.
      This change adds the classes services_autorun_inputs and
      services_autorun_bundles for independently enabling addition of .cf files in
      services/autorun and automatic execution of bundles tagged with autorun
      respectively.  (CFE-3715)
    - Added support for downloading community packages on hub in preparation for binary upgrades

    - Adjusted badges for 3.18.0 release (ENT-6713)
    - Adjusted permissions for Mission Portal public tmp files (ENT-7261)
    - Autorun bundles now run regardless of locks
      Previously, when the autorun feature was enabled to automatically run bundles
      tagged with autorun the bundle actuation was affected by promise locking. The
      effect of this is that agent runs that happen close together would skip running
      bundles run within the last minute. Now autorun bundles no longer wait for a
      lock to expire, they will be actuated each agent execution. Note, promises
      within those bundles have their own locks which still apply.  (CFE-3795)
    - Dropped un-necessary local variable
      The use of this local variable triggers a bug that prevents datastate() from
      printing. Since the variable is un-necessary, it's been removed and the
      parameter is used directly.  (CFE-3776)

    - Stopped enforcing permissions of modules in inputs
      This change removes explicit enforcement of permissions for modules in inputs.
      Instead of explicitly enforcing permissions in inputs, we rely on the default
      permissions (600). The previous explicit permissions (755) are un-necessary as
      modules are not executed from within the inputs directory and have resulted in
      permission flip-flopping in some environments. Permissions on modules in the
      modules dir (sys.workdir)/modules are still enforced.  (ENT-7733)
    - Switched from using package_method generic to default package_module
      for windows software inventory (ENT-2589)

      defined redhat and we do not find classes for well known derivatives
    - rocky, a class defined on Rocky Linux was added to the list of well known derivatives
      (ENT-7628)
    - Added advisory lock for Federated Reporting operations (ENT-7474)
    - controls/cf_serverd.cf no longer specifies explicit
      default for bindtointerface and relies on the default
      binding to both :: and 0.0.0.0 on IPV6-enabled hosts
      (ENT-7362)
    - setup-status.json is no longer being repaired over and over on FR feeder hubs
      (ENT-7967)

      (ENT-6673)
    - Added verbose logfile for msiexec package module file installs
      (ENT-6220, ENT-6824)
    - Changed default behavior of policy update to keep inputs in sync with masterfiles
      Prior to this change, the default behavior of the MPF was to only ensure that
      files in masterfiles were up to date with the files in inputs. Files in inputs
      that did not exist in masterfiles were left undisturbed. To enable sync
      behavior (a common user expectation) you had to explicitly define
      'cfengine_internal_purge_policies'. Now, if you wish to return to the previous
      default behavior, define the class 'cfengine_internal_purge_policies_disabled'.

      type promises. Monitoring brings to mind alerting, which we handle as a
      subset of our Dashboards. This name change clarifies the content.
      (ENT-5023)
    - Changed session lock to allow parallel HTTP requests. Previously, the
      session library would create a lock and not allow new requests until
      the current one is not finished. This lock was introduced to avoid
      data overwriting when two or more parallel requests are writing into
      the same session variable, but this doesn't happen in our code

    - Fixed an issue with error handling in cf-hub delta queries
      cf-hub will now attempt a rebase if it cannot obtain the
      last report timestamp. This change only affects scheduled
      runs, not when invoked with `--query delta` from command
      line. This also means that hosts which are not present in
      status table will be rebased (not delta from 0). (ENT-4319)
    - Fixed an issue with manual cf-hub delta queries
      When invoked manually (cf-hub --query delta) it would request

    - Renamed the "Status" table to "__Status" with RBAC-checked view
      (ENT-4331)
    - Renamed Host count widget to Newly bootstrapped hosts (ENT-4649)
    - Simplified error handling and error messages for failed report collection
      (ENT-4495)
    - Switched perms of various temporary files in state to 0600
      These files were created with 0644 permissions, and then
      repaired in policy. However, since they are deleted / recreated
      periodically, it causes INFO noise. Safer and better user
      experience to create them with restricted permissions to
      begin with.
      Affected files:
      * `$(sys.statedir)/context.cache.tmp`
      * `$(sys.statedir)/variable.cache.tmp`
      * `$(sys.statedir)/diff/*.diff`
      * `$(sys.statedir)/previous_state/*.cache`
      (ENT-4601)
    - Updated links to postgresql docs to match running version (ENT-4436)
    - Updated role database entry on POST requests instead of deletion and creation
      This change was made to avoid deleting related to role entries because previously while role updating the database entry is deleted and recreated.
      (ENT-4483)
    - HTTPS protocol is now used in CLI commands (ENT-4361)
    - Fixed license count for hosts with duplicate entries in lastseen DB
      (ENT-4595)
    - Variable values can no longer be NULL in reporting
      The reporting system doesn't distinguish between NULL
      and empty string. Previously, variables with value
      "" would show up in psql as NULL. This can be
      cumbersome when writing queries, and doesn't
      accurately reflect the variable value in policy.
      NULLs are now converted to empty string before
      insert. This change only affects 2 tables in
      postgresql: "variables" and "variableslog".
      This change can trigger a rebase if you already
      have reporting data with variablevalue=NULL.
      (ENT-4093)

      from postgres
      The diagnostics measurement redis_processing_time_per_host has been

      - Full and delta reports send only mon and sys variables as also hosts excluding policy
        server are reporting only subset of monitoring data.
        This can be changed using access promise in default cf_serverd.cf policy.
    - Removed license checking on hosts.

    Bugfixes:
    - Mission Portal
      - promise finder now does string matching
      - assigning roles in user management now makes sense
      - report builder now has a "new query" button
      - blue hosts' lacking data history is indicated correctly now
      - CSS fixes
      - finders no longer load duplicate list items
      - Fix inconsistent behavior of black host status directly after install.
    - Enterprise API
      - Fix some REST queries not working on replica secondaries (eg. the /rest/host/:id)
    - Remove HTML output from Total Compliance report

3.0.x: Removed unused options "[-t][-r][-u]" from cf-know

3.0.1: $(sys.licenses_installtime) variable removed from "Enterprise Free"

3.0.0: New Reporting Engine: A SQL interface to reports collected by hub.

    We allow all standardised SQL SELECT constructs to query the SQL reports database, with the following additions:
    - TIMESTAMP_UNIX() - seconds elapsed since 1970
    - TIMESTAMP_UNIX_DAYS() - days elapsed since 1970
    These are added to avoid use of non-portable SQL date/time functions.

    Enterprise API:
    - Read + write REST interface for
      - report querying(utilizes underlying reporting engine)
      - user management
      - can be used with REST API v1 in parallel
    - Configurable hostnames(host/system identifier) in reports
    - can take any of the sys variables(eg.$(sys.fqhost))
    - When decommissioning (deleting a host) from the Mission Portal/Enterprise API,
      the public keys of the clients are also removed
    - Ability to delete multiple hosts from the mission portal
    - Improvements on the hub maintenance process
      less resource intensive and configurable
    - New option for cf-hub added (-m) for Enterprise database maintenance
    - Fixes on database connections problems
    - If you were seeing "connection refused because too many open connections",
      in database log please consider upgrading
    - Changed "nova>" to "enterprise>" in agent verbose output
    - Please update email filters
    - Removed internal CFE promises from reporting
    - New classes enterprise, enterprise_X, enterprise_X_Y, enterprise_X_Y_Z
      on CFEngine Enterprise, to reflect the version running. New variable
      sys.enterprise_version that holds the CFEngine Enterprise version.
      This complements the Nova classes and the sys.nova_version variable,
      which will eventually be deprecated.
    - Fix file change report containing warning message as filename for new/deleted files
    - File diff log (nova_diff.log) have been extended with promise handle name.
    - Total compliance output in cf-agent verbose mode and promise_summary.log
      have been extended with user and cfengine internal compliance level.
    - System variables are collected by hub in every delta query
    - Fix software reports showing "(never)" in the "Last seen" column
    - Fix "blue hosts" list being empty for clients that don't have class keys
    - Sendmail is installed by default on the hub - required for emailing of reports
    - 32-bit hub installations no longer supported
    - Created a variable update_policy.mongodb_dir, for cases where MongoDB
      should not run out of /var/cfengine/state (could grow to tens of gigabytes).
    - Removed commercial_customer class, as it was unused in internal policies.
      Please use enterprise_edition instead if you used this in your policies.
    - New performance report events: DBPurgeHostsAll, DBMaintenance,
      DBMaintenanceTimestampsSingleHost, DBCacheCompliance, DBReportCollectAll.
    - License verification is made more robust by not relying on the last-seen
      database anymore. This means you do not need to bootstrap a client to
      verify the license. See the cf-key --install-license option.

2.2.0
    - More diagnostics on report collection from cf-hub. Logging more
      useful information in cf-hub -l, measuring total collection time
      in benchmarks report, under id "ReportCollectAll".
    - Fixed issue where client would show as green in the Mission Portal when no
      data was received, e.g. due to access or license error at client.
      Now correctly shows as blue in these cases.
    - Greatly reduced amount of connections from cf-hub
      to localhost mongodb. Now there is one connection per
      cf-hub run (max 50), before it was three per client.
    - Software and variable report now contains end-node discovery time.
    - Software and patches available/status reports contain maximum 5-minute old data,
      improved from 6 hours in last release. This will only apply to clients
      that are upgraded to 2.2.0.
    - Software report query from Mission Portal is much faster on larger data-sets due
      to removal of autocomplete feature.
    - Upgraded mongod from version 1.8.2 to 2.0.4, which increases
      efficiency on concurrency and reduces memory usage.
    - New function hostswithclass() that generates a list of hosts in a given class
      on the hub.
    - The bundled failsafe.cf policy now has trustkey=false to avoid IP spoofing
      attacks in default policy

2.1.0
    - New interface with interactive graphs on Nova hub.
    - User management on hub.
    - Allowing TAB in file diff report. Better handling
      of large diffs and attempts to diff binaries.
    - Support for adding notes to all hosts and reports.
    - Support for policy staging environments.
    - Nova reports can be exported to file and imported manually
      using cf-report -x and cf-report -i.
    - Faster collection of monitoring (vitals) data due to
      new protocol and data structure.
    - Long-term storage (one year) of diff and changes reports.
    - The variables report got a last-seen column. Now variables
      are stored in the hub for a longer time like classes,
      and not overwritten on every update.
    - The report of reports-promises are shown in the promise repaired log
      in the Mission Portal.
    - New option cf-hub --cache, recreates the cache data needed
      by the web interface.
    - Only showing the last seen host name and ip address when
      listing hosts and on the host page.
    - Reliability improvements, especially when querying
      the variables report.

2.0.2
    - Much faster report querying.
    - Allows to specify age interval when querying promise not
      kept and repaired.
    - Promiser conflict identifcation.
    - Built with Cfengine Community Edition 3.1.4.

2.0.1
    - Fixed promise query of not kept/promise repaired logs.

1.2.0:
    - Windows Event Logs include output_prefix if set, and which component
      reported the event. The verbosity of event logs have been reduced
      by not including promise kept and repaired events, this can now be
      tuned with action.log_level.
    - Take out network communications from total state calculation,
      as it gets counted twice.

1.1.2:
    - Encryption problems fixed in Community Edition.
    - Built with Cfengine Community Edition 3.0.4p3.

1.1.0:
    - Regular expressions in file paths supported on Windows by using
      forward slash as path separator.
    - CPU utilization report on Windows.
      Users logged in report on Windows.
    - On the Windows cf-serverd, requests for /var/cfengine are
      translated to $(sys.workdir)\Cfengine, and path separators are
      automatically adjusted ("/" becomes "\"). This yields support for
      more platform-independent promises and allows for automatic
      copying of reports from Windows clients to the policy server.
    - Scale on graphs in the Knowledge Map, and different background
      color gives more readability.
    - Special functions added for accessing remote classes for distributed cooperation.

1.0.0:
    - Reports added to cf-report for compliance, setuid, file_changes etc.
      Added csv format also
    - Automating topic map integration of policy, with impact analysis
      using promisee and builds_on promises.
    - Literal string lookup in server.
    - Database SQL and registry functions added. Verification and sanity
      checking of SQL database table structure. Create and destroy
      databases convergently.
    - Access control list support for Linux.
    - Powerful and lightweight promises for Customizable monitoring and
      system discovery promises added to cf-monitord.
    - Longterm memory for 3 year trend analysis.

In general, CFEngine is known to run on a wide range of other platforms. As long as the platform is POSIX compliant and has a C compiler toolchain that fully implements the C99 standard, we are happy to work with you to make CFEngine available. Please contact our sales team for details.


Known issues

CFEngine defects are managed in our bug tracker. Please report bugs or unexpected behavior there, following the documented guideline for new bug reports.

  • Core Issues affecting 3.23

The items below highlight issues that require additional awareness when starting with CFEngine or when upgrading from a previous version.

cf-agent -N or cf-agent --negate is not working

As reported in CFE-1589 the functionality of negating persistent classes on the command line, was removed sometime before 3.5, commit cf63db27945f0628caa5bf45338f7709d5d12b21. The ticket is open until the functionality is reinstated.

HP-UX specific
  • Package promises do not have out-of-the-box support for the HP-UX specific package manager. The workaround is to call the package manager directly using commands promises.
  • Some important system information is missing from the HP-UX inventory report, as well as from CFEngine hard classes and system variables. The workaround is to use system tools to obtain the required information and set classes based on this. * Disk free * Memory size * Several OS and architecture specific attributes * System version * System serial number * System manufacturer * CPU model * BIOS version * BIOS vendor
  • Process promises depend on the ps native tool, which by default truncates lines at 128 columns on HP-UX. It is recommended to edit the file /etc/default/ps and increase the DEFAULT_CMD_LINE_WIDTH setting to 1024 to guarantee that process promises will work smoothly on the platform.
  • Upgrading CFEngine on HP-UX is not supported by the out-of-the-box policy. There is a support article with a workaround.
Enterprise monitoring graphs

Monitoring graphs are disabled by default in CFEngine Enterprise 3.6 and later versions. To enable them, change monitoring_include in masterfiles/controls/reports.cf to e.g. ".*". Note that this can have significant impact on the resource consumption of your hub.

Monitoring graphs are not supported on all platforms, currently AIX, HP-UX and Windows do not have this data.

Enterprise inventory CSV report is empty (0 bytes)

Exporting a CSV-based inventory report can result in a 0-byte length file if the CFEngine Server is accessed over https and the certificate's CN mismatches with the URL you use to export the report. To verify this is the problem, check the Mission Portal application logs (currently at /var/cfengine/httpd/htdocs/application/logs) on the CFEngine Server. If you see lines like the following you affected by this issue.

code
ERROR - 2016-06-15 07:24:15 --> Severity: Warning --> readfile(): Peer certificate CN=`myhostname.example.com' did not match expected CN=`myhostname' /var/cfengine/httpd/htdocs/application/helpers/cf_util_helper.php 612
ERROR - 2016-06-15 07:24:15 --> Severity: Warning --> readfile(): Failed to enable crypto /var/cfengine/httpd/htdocs/application/helpers/cf_util_helper.php 612
ERROR - 2016-06-15 07:24:15 --> Severity: Warning --> readfile(https://myhostname/api/static/e39cfd50f95a853fb103a89477b46eb8.csv): failed to open stream: operation failed /var/cfengine/httpd/htdocs/application/helpers/cf_util_helper.php 612

The solution is to generate a new certificate with the correct CN, i.e. the one you use to access the CFEngine Server. To see how to do this, look at the documentation for using a Custom SSL certificate.

Enterprise software inventory is not out-of-the-box

Software inventory is not out-of-the-box for reporting from the hub on other platforms than Debian, Ubuntu and Red Hat/CentOS.

In order to add software inventory for other platforms, please contact support for a custom policy.
