Ansible Changes By Release

0.6 "Cabo" ------------ pending

playbooks:

support to tag tasks and includes and use --tags in playbook CLI
playbooks can now include other playbooks (example/playbooks/nested_playbooks.yml)
vars_files now usable with with_items, provided file paths don't contain host specific facts
error reporting if with_items value is unbound
with_items no longer creates lots of tasks, creates one task that makes multiple calls
can use host_specific facts inside with_items (see above)
at the top level of a playbook, set 'gather_facts: False' to skip fact gathering
first_available_file and with_items used together will now raise an error
to catch typos, like 'var' for 'vars', playbooks and tasks now yell on invalid parameters
automatically load (directory_of_inventory_file)/group_vars/groupname and /host_vars/hostname in vars_files
playbook is now colorized, set ANSIBLE_NOCOLOR=1 if you do not like this, does not colorize if not a TTY
hostvars now preserved between plays (regression in 0.5 from 0.4), useful for sharing vars in multinode configs
ignore_errors: True on a task can be used to allow a task to fail and not stop the play
with_items with the apt module will install/remove/update everything in a single command (yum pending)

inventory:

groups variable available as a hash to return the hosts in each group name
in YAML inventory, hosts can list their groups in inverted order now also (see tests/yaml_hosts)
YAML inventory is deprecated and will be removed in 0.7
ec2 inventory script
support ranges of hosts in the host file, like www[001-100].example.com (supports leading zeros and also not)

modules:

fetch module now does not fail a system when requesting file paths (ex: logs) that don't exist
apt module now takes an optional install-recommends=yes|no (default yes)
fixes to the return codes of the copy module
copy module takes a remote md5sum to avoid large file transfer
various user and group module fixes (error handling, etc)
apt module now takes an optional force parameter
slightly better psychic service status handling for the service module
fetch module fixes for SSH connection type
modules now consistently all take yes/no for boolean parameters (and DWIM on true/false/1/0/y/n/etc)
setup module no longer saves to disk, template module now only used in playbooks
setup module no longer needs to run twice per playbook
apt module now passes DEBIAN_FRONTEND=noninteractive
mount module (manages active mounts + fstab)
setup module fixes if no ipv6 support
internals: template in common module boilerplate, also causes less SSH operations when used
git module fixes
setup module overhaul, more modular
minor caching logic added to inventory to reduce hammering of inventory scripts.
MySQL and PostgreSQL modules for user and db management
vars_prompt now supports private password entry (see examples/playbooks/prompts.yml)

internals:

when sudoing to root, still use /etc/ansible/setup as the metadata path, as if root
paramiko is now only imported if needed when running from source checkout
cowsay support on Ubuntu
various ssh connection fixes for old Ubuntu clients
./hacking/test-module now supports options like ansible takes and has a debugger mode
sudoing to a user other than root now works more seamlessly (uses /tmp, avoids umask issues)

0.5 "Amsterdam" ------- July 04, 2012

Service module gets more accurate service states when running with upstart
Jinja2 usage in playbooks (not templates), reinstated, supports %include directive
support for --connection ssh (supports Kerberos, bastion hosts, etc), requires ControlMaster
misc tracebacks replaced with error messages
various API/internals refactoring
vars can be built from other variables
support for exclusion of hosts/groups with "!groupname"
various changes to support md5 tool differences for FreeBSD nodes & OS X clients
"unparseable" command output shows in command output for easier debugging
mktemp is no longer required on remotes (not available on BSD)
support for older versions of python-apt in the apt module
a new "assemble" module, for constructing files from pieces of files (inspired by Puppet "fragments" idiom)
ability to override most default values with ANSIBLE_FOO environment variables
--module-path parameter can support multiple directories seperated with the OS path seperator
with_items can take a variable of type list
ansible_python_interpreter variable available for systems with more than one Python
BIOS and VMware "fact" upgrades
cowsay is used by ansible-playbook if installed to improve output legibility (try installing it)
authorized_key module
SELinux facts now sourced from the python selinux library
removed module debug option -D
added --verbose, which shows output from successful playbook operations
print the output of the raw command inside /usr/bin/ansible as with command/shell
basic setup module support for Solaris
./library relative to the playbook is always in path so modules can be included in tarballs with playbooks

0.4 "Unchained" ------- May 23, 2012

Internals/Core

internal inventory API now more object oriented, parsers decoupled
async handling improvements
misc fixes for running ansible on OS X (overlord only)
sudo improvements, now works much more smoothly
sudo to a particular user with -U/--sudo-user, or using 'sudo_user: foo' in a playbook
--private-key CLI option to work with pem files

Inventory

can use -i host1,host2,host3:port to specify hosts not in inventory (replaces --override-hosts)
ansible INI style format can do groups of groups [groupname:children] and group vars [groupname:vars]
groups and users module takes an optional system=yes|no on creation (default no)
list of hosts in playbooks can be expressed as a YAML list in addition to ; delimited

Playbooks

variables can be replaced like ${foo.nested_hash_key.nested_subkey[array_index]}
unicode now ok in templates (assumes utf8)
able to pass host specifier or group name in to "hosts:" with --extra-vars
ansible-pull script and example playbook (extreme scaling, remediation)
inventory_hostname variable available that contains the value of the host as ansible knows it
variables in the 'all' section can be used to define other variables based on those values
'group_names' is now a variable made available to templates
first_available_file feature, see selective_file_sources.yml in examples/playbooks for info
--extra-vars="a=2 b=3" etc, now available to inject parameters into playbooks from CLI

Incompatible Changes

jinja2 is only usable in templates, not playbooks, use $foo instead
--override-hosts removed, can use -i with comma notation (-i "ahost,bhost")
modules can no longer include stderr output (paramiko limitation from sudo)

Module Changes

tweaks to SELinux implementation for file module
fixes for yum module corner cases on EL5
file module now correctly returns the mode in octal
fix for symlink handling in the file module
service takes an enable=yes|no which works with chkconfig or updates-rc.d as appropriate
service module works better on Ubuntu
git module now does resets and such to work more smoothly on updates
modules all now log to syslog
enabled=yes|no on a service can be used to toggle chkconfig & updates-rc.d states
git module supports branch=
service fixes to better detect status using return codes of the service script
custom facts provided by the setup module mean no dependency on Ruby, facter, or ohai
service now has a state=reloaded
raw module for bootstrapping and talking to routers w/o Python, etc

Misc Bugfixes

fixes for variable parsing in only_if lines
misc fixes to key=value parsing
variables with mixed case now legal
fix to internals of hacking/test-module development script

0.3 "Baluchitherium" -- April 23, 2012

Packaging for Debian, Gentoo, and Arch
Improvements to the apt and yum modules
A virt module
SELinux support for the file module
Ability to use facts from other systems in templates (aka exported resources like support)
Built in Ansible facts so you don't need ohai, facter, or Ruby
tempdir selections that work with noexec mounted /tmp
templates happen locally, not remotely, so no dependency on python-jinja2 for remote computers
advanced inventory format in YAML allows more control over variables per host and per group
variables in playbooks can be structured/nested versus just a flat namespace
manpage upgrades (docs)
various bugfixes
can specify a default --user for playbooks rather than specifying it in the playbook file
able to specify ansible port in ansible host file (see docs)
refactored Inventory API to make it easier to write scripts using Ansible
looping capability for playbooks (with_items)
support for using sudo with a password
module arguments can be unicode
A local connection type, --connection=local, for use with cron or in kickstarts
better module debugging with -D
fetch module for pulling in files from remote hosts
command task supports creates=foo for idempotent semantics, won't run if file foo already exists
