• print the output of the raw command inside /usr/bin/ansible as with command/shell

• ./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

• A local connection type, --connection=local, for use with cron or in kickstarts
• better module debugging with -D
