3.6.0 Beta 1
Changes:
- TLS authentication and fully encrypted network protocol. Changes
specific to the new type of connections:
- There is the choice of switching to a new networking protocol, which
uses TLS for authentication, after which all dialog happens encrypted
within the established TLS session. The hub is still able to speak
the legacy protocol with old agents.
- For the connections using the new protocol, "admit" and "deny"
constraints in bundle server access_rules are being phased out,
preferred constraints are now "admit_ips", "admit_hostnames",
"admit_keys". Regular expressions are not allowed then, only CIDR
notation for "admit_ips", exact "SHA=..." strings for "admit_keys",
and exact hostnames (e.g. "cfengine.com") or subdomains (starting
with dot, e.g. ".cfengine.com") for admit_hostnames.
- 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.
- The 'skipverify' option in body server control is deprecated and
only left for compatibility; it does nothing
- 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 does not hang up the connection if some request fails,
so that the client can add more requests.
- Enable source file in agent copy_from promises to be a relative path.
- #TODO# Changes to logging output
- add process name and pid in syslog message (GitHub #789)
- 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)
- Logging contexts to local database (cf_classes.tcdb) has been deprecated.
- Linux flavor "SUSE" now correctly spelled with all uppercase in variables and class names
(Redmine #3734).
- $(this.promise_filename) and $(..._dirname) variables are now absolute paths. (Redmine #3839)
New features:
- cf-serverd now logs the relevant client IP address on each message.
- New promise type "users" for managing local user accounts.
- New in 'bundle server access_rules'
- Constraints "admit_ips", "admit_hostnames", "admit_keys"
- "admit_keys" adds the new functionality of controlling access according to
host identity, regardless of the connecting IP.
- These new constaints and the paths in access_rules, can contain
special variables "$(connection.ip)", "$(connection.hostname)",
"$(connection.key)", which are expanded dynamically for every
received connection.
- New "shortcut" constraint in bundle server access_rules used to
dynamically expand non-absolute request paths.
- 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'
- 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
- 'datastate' - create a data variable with currently set classes and variables
- 'datatype' - #TODO#
- 'format' - %S can be used to serialize 'data' containers into a string
- 'mergedata' - merge two data containers
- 'parsejson' - create a data container from a JSON string
- 'readjson' - create a data container from a file that contains JSON
- 'storejson' - serialize a data container into a string
- Most functions operating on lists can also operate on data containers
- 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
- 'getclassmetatags' - returns list of meta tags for a class
- 'getvariablemetatags' - returns list of meta tags for a variable
- #TODO# transitive inputs
- New attributes in existing promise types and bodies
- Introduced alias 'policy_server' for context 'am_policy_hub' (the latter will be deprecated)
- New option 'preserve_all_lines' for insert_type in insert_lines promises
- Caching of expensive system functions to avoid multiple executions of
execresults() 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
'template_data' attributes
- New variables
- 'sys.bindir' - the location of the CFEngine binaries
- 'sys.failsafe_policy_path' - the location of the failsafe policy file
- 'sys.inputdir' - the directory where CFEngine searches for policy files
- 'sys.key_digest' - the digest of the host's cryptographic key
- 'sys.libdir', 'sys.local_libdir' - the location of the CFEngine libraries
- 'sys.masterdir' - the location of masterfiles on the policy server
- 'sys.sysday' - the number of days since the beginning of the UNIX epoch
- 'sys.systime' - the number of seconds since the beginning of the UNIX epoch
- 'sys.update_policy_path' - the name of the update policy file
- 'sys.uptime' - the number of minutes the host has been online
- 'this.promise_dirname' - the name of the file in which the current promise is defined
- 'this.promiser_uid' - the ID of the user running cf-agent
- 'this.promiser_gid' - the group ID of the user running cf-agent
- 'this.promiser_ppid' - the ID of the parent process running cf-agent
- New and improved functions
- 'bundlesmatching' - returns list of defined bundles matching a regex
- 'canonifyuniquely' - converts a string into a unique, legal class name
- 'classesmatching' - returns list of set classes matching a regex
- 'eval' - evaluates mathematical expressions
- 'findfiles' - returns list of files matching a search pattern
- 'makerule' - evaluates whether a target file needs to be rebuilt from sources
- 'max', 'mean', 'min' - returns maximum, mean and minimum in a container or list
- 'packagesmatching' - returns a filtered list of installed packages.
- 'string_downcase', 'string_upcase' - returns the lower-/upper-case version of a string
- 'string_head', 'string_tail' - returns the beginning/end of a string
- 'string_length' - returns the length of a string
- 'string_reverse' - reverses a string
- 'variablesmatching' - returns a list of variables matching a regex
- 'variance' - returns the variance of numbers in a list
- #TODO# support for LMDB in local data storage
- #TODO# replace_patterns changes
Bug fixes: #TODO#
- #TODO# goodness from evaluator and variable table refactoring
- `this` and similar variables ...?
- Improve performance of list iteration (Redmine #1875)
- Removed limitation of input length to internal buffer sizes
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:
<package-being-considered> <package_select> <package_version>
For instance:
apache-2.2.31 ">=" "2.2.0"
will result in the package being installed.
Bug fixes:
- fix cf-monitord crash due to incorrect array initialization (Redmine #3180)
- fix cf-serverd stat()'ing the file tree every second (Redmine #3479)
- correctly populate sys.hardware_addresses variable (Redmine #2936)
- add support for Debian's GNU/kfreebsd to build system (Redmine #3500)

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)

3.5.0
New features:
- classes promises now take an optional scope constraint.
- new built-in functions: every, none, some, nth, sublist, uniq, filter
- every
- none
- some
- 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)

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)
- create promise-defined and persistent classes in correct
namespace (Redmine #1836)
- several fixes to namespace support
- fix several crash bugs caused by buffer overflow and race
conditions in cf-serverd
- regenerate time classes in cf-execd for each run (Redmine #1838)
- edit_xml: fix select_xpath implementation and update documentation
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_<name>" 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 refering to non-existant 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 $PATH).
- Workdir location is properly changed if --prefix or --enable-fhs
options are supplied to configure (Mantis #1195).
- Added check for broken libmysqlclient implementations (Mantis #1217).
- Standard library is updated from COPBL repository.
- cf-know is no longer built in Community releases. The only
functionality useful in Community, namely the reference manual
generation, is provided by new compile-time cf-gendoc tool.
- Filename (for storing filechanges) changed
from file_change.log -> file_changes.log (in /var/cfengine/state)
New format for storing file changes introduced:
[timestamp,filename,<N/C/S/R>,Message]
N = New file found
C = Content Changed
S = Stats changed
R = File removed
- Acceptance test suite passes on Mac OS X.
- Changed some port numbers to replace old services with imap(s)
- archlinux hard class on Arch Linux.
- Detect BSD Make and automatically switch to GNU Make during build.
Bugfixes:
- cfruncommand for cf-execd is an arbitrary shell command now (Mantis #1268).
- Fixed broken "daily" splayclasses (Mantis #1307).
- Allow filenames up to 4096 bytes in network transfers (Redmine #1199).
- Fix stale state preserved during cf-serverd reload (Redmine #1487).
- Free disk space calculation is fixed (Mantis #1120).
- Numerous portability bugfixes (especially OpenBSD, Solaris, AIX-related).
- Compatibility fixes for AIX, HP-UX, Solaris (Mantis #1185, Mantis #1177, Mantis #1109).
- Fixed broken socklen_t configure check under OpenBSD (Mantis #1168).
- Fixed hang in cf-promises under OpenBSD (Mantis #1113).
- Fixed endless loop in evaluating "$()" 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 recieve 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_<mac_address>:: - 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

Reorganization of documentation and community resources
100% on regression test suite on 3 operating systems
(Ubuntu, Debian, SuSE on x86-64 hardware)

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.
Invalidation of package list cache on installation/removal of
packages.

Added detection of network interfaces which belong to BSD jails.
Improve robustness of multi-threaded code, in particular fix
problems with spurious acces 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 efficent 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.
Seg fault in mount files fix.
Twin used in cf-execd without checking.
Check_root set wrong directory permissions at source not destination.
Error message degraded in body definition.
Undefined body not warned as error.
