0.8 "Cathedral" -- Oct 19, 2012
Highlighted Core Changes:
- fireball mode -- ansible can bootstrap a ephemeral 0mq (zeromq) daemon that runs as a given user and expires after X period of time. It is very fast.
- playbooks with errors now return 2 on failure. 1 indicates a more fatal syntax error. Similar for /usr/bin/ansible
- server side action code (template, etc) are now fully pluggable
- ability to write lookup plugins, like the code powering "with_fileglob" (see below)
Other Core Changes:
- ansible config file can also go in '.ansible.cfg' in cwd in addition to ~/.ansible.cfg and /etc/ansible/ansible.cfg
- fix for inventory hosts at API level when hosts spec is a list and not a colon delimited string
- ansible-pull example now sets up logrotate for the ansible-pull cron job log
- negative host matching (!hosts) fixed for external inventory script usage
- internals: os.executable check replaced with utils function so it plays nice on AIX
- Debian packaging now includes ansible-pull manpage
- magic variable 'ansible_ssh_host' can override the hostname (great for usage with tunnels)
- date command usage in build scripts fixed for OS X
- don't use SSH agent with paramiko if a password is specified
- make output be cleaner on multi-line command/shell errors
- /usr/bin/ansible now prints things when tasks are skipped, like when creates= is used with -m command and /usr/bin/ansible
- when trying to async a module that is not a 'normal' asyncable module, ansible will now let you know
- ability to access inventory variables via 'hostvars' for hosts not yet included in any play, using on demand lookups
- merged ansible-plugins, ansible-resources, and ansible-docs into the main project
- you can set ANSIBLE_NOCOWS=1 if you want to disable cowsay if it is installed. Though no one should ever want to do this! Cows are great!
- you can set ANSIBLE_FORCECOLOR=1 to force color mode even when running without a TTY
- fatal errors are now properly colored red.
- skipped messages are now cyan, to differentiate them from unchanged messages.
- extensive documentation upgrades
- delegate_action to localhost (aka local_action) will always use the local connection type
Highlighted playbook changes:
- is_set is available for use inside of an only_if expression: is_set('ansible_eth0'). We intend to further upgrade this with a 'when' keyword providing better options to 'only_if' in the next release. Also is_unset('ansible_eth0')
- playbooks can import playbooks in other directories and then be able to import tasks relative to them
- FILE($path) now allows access of contents of file in a path, very good for use with SSH keys
- similarly PIPE($command) will run a local command and return the results of executing this command
- if all hosts in a play fail, stop the playbook, rather than letting the console log spool on by
- only_if using register variables that are booleans now works in a boolean way like you'd expect
- task includes now work with with_items (such as: include: path/to/wordpress.yml user=$item)
- when using a $list variable with $var or ${var} syntax it will automatically join with commas
- setup is not run more than once when we know it is has already been run in a play that included another play, etc
- can set/override sudo and sudo_user on individual tasks in a play, defaults to what is set in the play if not present
- ability to use with_fileglob to iterate over local file patterns
- templates now use Jinja2's 'trim_blocks=True' to avoid stray newlines, small changes to templates may be required in rare cases.
Other playbook changes:
- to_yaml and from_yaml are available as Jinja2 filters
- $group and $group_names are now accessible in with_items
- where 'stdout' is provided a new 'stdout_lines' variable (type == list) is now generated and usable with with_items
- when local_action is used the transport is automatically overridden to the local type
- output on failed playbook commands is now nicely split for stderr/stdout and syntax errors
- if local_action is not used and delegate_to was 127.0.0.1 or localhost, use local connection regardless
- when running a playbook, and the statement has changed, prints 'changed:' now versus 'ok:' so it is obvious without colored mode
- variables now usable within vars_prompt (just not host/group vars)

- --sudo-user now works with --extra-vars
- fix for multi_line strings with only_if
New Modules:
- ini_file module for manipulating INI files
- new LSB facts (release, distro, etc)
- pause module -- (pause seconds=10) (pause minutes=1) (pause prompt=foo) -- it's an action plugin
- a module for adding entries to the main crontab (though you may still wish to just drop template files into cron.d)

- postgresql modules now take an optional port= parameter
- /proc/cmdline info is now available in Linux facts
- public host key detection for OS X

- additional facts for SunOS virtualization
- copy module is now atomic when used across volumes
- url_get module now returns 'dest' with the location of the file saved

- service module status now correct for services with 'subsys locked' status
- misc fixes/upgrades to the wait_for module
- git module now expands any "~" in provided destination paths
- ignore stop error code failure for service module with state=restarted, always try to start
