## 1.9 "Dancing In the Street" - Mar 25, 2015

Major changes:

* Added kerberos support to winrm connection plugin.
* Tags rehaul: added 'all', 'always', 'untagged' and 'tagged' special tags and normalized
  tag resolution. Added tag information to --list-tasks and new --list-tags option.
* Privilege Escalation generalization, new 'Become' system and variables  now will
  handle existing and new methods. Sudo and su have been kept for backwards compatibility.
  New methods pbrun and pfexec in 'alpha' state, planned adding 'runas' for winrm connection plugin.
* Improved ssh connection error reporting, now you get back the specific message from ssh.
* Added facility to document task module return values for registered vars, both for
  ansible-doc and the docsite. Documented copy, stats and acl modules, the rest must be
  updated individually (we will start doing so incrementally).
* Optimize the plugin loader to cache available plugins much more efficiently.
  For some use cases this can lead to dramatic improvements in startup time.
* Overhaul of the checksum system, now supports more systems and more cases more reliably and uniformly.
* Fix skipped tasks to not display their parameters if no_log is specified.
* Many fixes to unicode support, standarized functions to make it easier to add to input/output boundaries.
* Added travis integration to github for basic tests, this should speed up ticket triage and merging.
* environment: directive now can also be applied to play and is inhertited by tasks, which can still override it.
* expanded facts and OS/distribution support for existing facts and improved performance with pypy.
* new 'wantlist' option to lookups allows for selecting a list typed variable vs a command delimited string as the return.
* the shared module code for file backups now uses a timestamp resolution of seconds (previouslly minutes).
* allow for empty inventories, this is now a warning and not an error (for those using localhost and cloud modules).
* sped up YAML parsing in ansible by up to 25% by switching to CParser loader.

New Modules:

* cryptab: manages linux encrypted block devices
* gce_img:  for utilizing GCE image resources
* gluster_volume: manage glusterfs volumes
* haproxy: for the load balancer of same name
* known_hosts: manages the ssh known_hosts file
* lxc_container: manage lxc containers
* patch: allows for patching files on target systems
* pkg5:  installing and uninstalling packages on Solaris
* pkg5_publisher: manages Solaris pkg5 repository configuration
* postgresql_ext: manage postgresql extensions
* snmp_facts: gather facts via snmp
* svc: manages daemontools based services
* uptimerobot: manage monitoring with this service

New Filters:

* ternary: allows for trueval/falseval assignment dependent on conditional
* cartesian: returns the Cartesian product of 2 lists
* to_uuid: given a string it will return an ansible domain specific UUID
* checksum: uses the ansible internal checksum to return a hash from a string
* hash: get a hash from a string (md5, sha1, etc)
* password_hash: get a hash form as string that can be used as a password in the user module (and others)
* A whole set of ip/network manipulation filters: ipaddr,ipwrap,ipv4,ipv6ipsubnet,nthhost,hwaddr,macaddr

Other Notable Changes:

* New lookup plugins:
  * dig: does dns resolution and returns IPs.
  * url: allows pulling data from a url.
* New callback plugins:
  * syslog_json: allows logging play output to a syslog network server using json format
* Many new enhancements to the amazon web service modules:
  * ec2 now applies all specified security groups when creating a new instance.  Previously it was only applying one
  * ec2_vol gained the ability to specify the EBS volume type
  * ec2_vol can now detach volumes by specifying instance=None
  * Fix ec2_group to purge specific grants rather than whole rules
  * Added tenancy support for the ec2 module
  * rds module has gained the ability to manage tags and set charset and public accessibility
  * ec2_snapshot module gained the capability to remove snapshots
  * Add alias support for route53
  * Add private_zones support to route53
  * ec2_asg: Add wait_for_instances parameter that waits until an instance is ready before ending the ansible task
* Many new docker improvements:
  * restart_policy parameters to configure when the container automatically restarts
  * If the docker client or server doesn't support an option, the task will now fail instead of silently ignoring the option
  * Add insecure_registry parameter for connecting to registries via http
  * New parameter to set a container's domain name
  * Undeprecated docker_image module until there's replacement functionality
  * Allow setting the container's pid namespace
  * Add a pull parameter that chooses when ansible will look for more recent images in the registry
  * docker module states have been greatly enhanced.  The reworked and new states are:
    * present now creates but does not start containers
    * restarted always restarts a container
    * reloaded restarts a container if ansible detects that the configuration is different than what is specified
      * reloaded accounts for exposed ports, env vars, and volumes
  * Can now connect to the docker server using TLS
* Several source control modules had force parameters that defaulted to true.
  These have been changed to default to false so as not to accidentally lose
  work.  Playbooks that depended on the former behaviour simply need to add
  force=True to the task that needs it.  Affected modules:
  * bzr: When local modifications exist in a checkout, the bzr module used to
    default to removing the modifications on any operation.  Now the module
    will not remove the modifications unless force=yes is specified.
    Operations that depend on a clean working tree may fail unless force=yes is
    added.
  * git: When local modifications exist in a checkout, the git module will now
    fail unless force is explicitly specified.  Specifying force=yes will allow
    the module to revert and overwrite local modifications to make git actions
    succeed.
  * hg: When local modifications exist in a checkout, the hg module used to
    default to removing the modifications on any operation.  Now the module
    will not remove the modifications unless force=yes is specified.
  * subversion: When updating a checkout with local modifications, you now need
    to add force=yes so the module will revert the modifications before updating.
* New inventory scripts:
  * vbox: virtualbox
  * consul: use consul as an inventory source
* gce gained the ip_forward parameter to forward ip packets
* disk_auto_delete parameter to gce that will remove the boot disk after an instance is destroyed
* gce can now spawn instances with no external ip
* gce_pd gained the ability to choose a disk type
* gce_net gained target_tags parameter for creating firewall rules
* rax module has new parameters for making use of a boot volume
* Add scheduler_hints to the nova_compute module for optional parameters
* vsphere_guest now supports deploying guests from a template
* Many fixes for hardlink and softlink handling in file-related modules
* Implement user, group, mode, and selinux parameters for the unarchive module
* authorized_keys can now use url as a key source
* authorized_keys has a new exclusive parameter that determines if keys that weren't specified in the task
* The selinux module now sets the current running state to permissive if state='disabled'
* Can now set accounts to expire via the user module
* Overhaul of the service module to make code simpler and behave better for systems running several popular init systems
* yum module now has a parameter to refresh its cache of package metadata
* apt module gained a build_dep parameter to install a package's build dependencies
* Add parameters to the postgres modules to specify a unix socket to connect to the db
* The mount module now supports bind mounts
* Add a clone parameter to git module that allows you to get information about a remote repo even if it doesn't exist locally.
* Add a refspec argument to the git module that allows pulling commits that aren't part of a branch
* Many documentation additions and fixes.

* ansible-galaxy install -f requirements.yml allows advanced options and installs from non-galaxy SCM sources and tarballs.
* command_warnings feature will warn about when usage of the shell/command module can be simplified to use core modules - this can be enabled in ansible.cfg
* new omit value can be used to leave off a parameter when not set, like so module_name: a=1 b={{ c | default(omit) }}, would not pass value for b (not even an empty value) if c was not set.
* developers: 'baby JSON' in module responses, originally intended for writing modules in bash, is removed as a feature to simplify logic, script module remains available for running bash scripts.
* async jobs started in "fire & forget" mode can now be checked on at a later time.
* added ability to subcategorize modules for docs.ansible.com

* cloud: rax_cdb_user - manages Rackspace Cloud Database users
* monitoring: zabbix_maintaince - handles outage windows with Zabbix
* monitoring: bigpanda - support for bigpanda
* net_infrastructure: a10_server - manages server objects on A10 devices
* net_infrastructure: a10_service_group - manages service group objects on A10 devices
* net_infrastructure: a10_virtual_server - manages virtual server objects on A10 devices
* system: getent - read getent databases

Some other notable changes:

* added the ability to set "instance filters" in the ec2.ini to limit results from the inventory plugin.
* upgrades for various variable precedence items and parsing related items
* added a new "follow" parameter to the file and copy modules, which allows actions to be taken on the target of a symlink rather than the symlink itself.
* if a module should ever traceback, it will return a standard error, catchable by ignore_errors, versus an 'unreachable'
* ec2_lc: added support for multiple new parameters like kernel_id, ramdisk_id and ebs_optimized.
* ec2_elb_lb: added support for the connection_draining_timeout and cross_az_load_balancing options.
* support for symbolic representations (ie. u+rw) for file permission modes (file/copy/template modules etc.).
* docker: Added support for specifying the net type of the container.
* docker: support for specifying read-only volumes.
* docker: support for specifying the API version to use for the remote connection.

* ec2_ami_search: support for SSD and IOPS provisioned EBS images
* can set ansible_sudo_exe as an inventory variable which allows specifying
  a different sudo (or equivalent) command
* git module: Submodule handling has changed.  Previously if you used the
  ``recursive`` parameter to handle submodules, ansible would track the
  submodule upstream's head revision.  This has been changed to checkout the
  version of the submodule specified in the superproject's git repository.
  This is inline with what git submodule update does.  If you want the old
  behaviour use the new module parameter track_submodules=yes
* Checksumming of transferred files has been made more portable and now uses
  the sha1 algorithm instead of md5 to be compatible with FIPS-140.
  - As a small side effect, the fetch module no longer returns a useful value
    in remote_md5.  If you need a replacement, switch to using remote_checksum
    which returns the sha1sum of the remote file.
* ansible-doc CLI tool contains various improvements for working with different terminals

* Added a -vvvv level, which will show SSH client debugging information in the event of a failure.
* Includes now support the more standard syntax, similar to that of role includes and dependencies. 
* Changed the `user:` parameter on plays to `remote_user:` to prevent confusion with the module of the same name.  Still backwards compatible on play parameters.

* new /etc/ansible/facts.d allows JSON or INI-style facts to be provided from the remote node, and supports executable fact programs in this dir. Files must end in *.fact.
* added the ability to make undefined template variables raise errors (see ansible.cfg)
* (DOCS PENDING) sudo: True/False and sudo_user: True/False can be set at include and role level
* added changed_when: (expression) which allows overriding whether a result is changed or not and can work with registered expressions
* --extra-vars can now take a file as input, e.g., "-e @filename" and can also be formatted as YAML
* external inventory scripts may now return host variables in one pass, which allows them to be much more efficient for large numbers of hosts
* if --forks exceeds the numbers of hosts, it will be automatically reduced. Set forks to 0 and you get "as many forks as I have hosts" out of the box.
* enabled error_on_undefined_vars by default, which will make errors in playbooks more obvious
* role dependencies -- one role can now pull in another, with parameters of its own.
* added the ability to have tasks execute even during a check run (always_run).
* added the ability to set the maximum failure percentage for a group of hosts.

## 1.2.3 "Hear About It Later" (reprise) -- Aug 21, 2013

* Local security fixes for predictable file locations for ControlPersist and retry file paths on shared machines
on operating systems without kernel symlink/hardlink protections.

## 1.2.2 "Hear About It Later" (reprise) -- July 4, 2013

* Added a configuration file option [paramiko_connection] record_host_keys which allows the code that paramiko uses
to update known_hosts to be disabled.  This is done because paramiko can be very slow at doing this if you have a
large number of hosts and some folks may not want this behavior.  This can be toggled independently of host key checking
and does not affect the ssh transport plugin.  Use of the ssh transport plugin is preferred if you have ControlPersist
capability, and Ansible by default in 1.2.1 and later will autodetect.

## 1.2.1 "Hear About It Later" -- July 4, 2013

* Connection default is now "smart", which discovers if the system openssh can support ControlPersist, and uses
  it if so, if not falls back to paramiko.
* Host key checking is on by default.  Disable it if you like by adding host_key_checking=False in the [default]
  section of /etc/ansible/ansible.cfg or ~/ansible.cfg or by exporting ANSIBLE_HOST_KEY_CHECKING=False
* Paramiko now records host keys it was in contact with host key checking is on.  It is somewhat sluggish when doing this,
  so switch to the 'ssh' transport if this concerns you.

## 1.2 "Right Now" -- June 10, 2013

Core Features:

* capability to set 'all_errors_fatal: True' in a playbook to force any error to stop execution versus
  a whole group or serial block needing to fail
  usable, without breaking the ability to override in ansible
* ability to use variables from {{ }} syntax in mainline playbooks, new 'when' conditional, as detailed
  in documentation.  Can disable old style replacements in ansible.cfg if so desired, but are still active
  by default.
* can set ansible_ssh_private_key_file as an inventory variable (similar to ansible_ssh_host, etc)
* 'when' statement can be affixed to task includes to auto-affix the conditional to each task therein
* cosmetic: "*****" banners in ansible-playbook output are now constant width
* --limit can now be given a filename (--limit @filename) to constrain a run to a host list on disk
* failed playbook runs will create a retry file in /var/tmp/ansible usable with --limit
* roles allow easy arrangement of reusable tasks/handlers/files/templates
* pre_tasks and post_tasks allow for separating tasks into blocks where handlers will fire around them automatically
* "meta: flush_handler" task capability added for when you really need to force handlers to run
* new --start-at-task option to ansible playbook allows starting at a specific task name in a long playbook
* added a log file for ansible/ansible-playbook, set 'log_path' in the configuration file or ANSIBLE_LOG_PATH in environment
* debug mode always outputs debug in playbooks, without needing to specify -v
* external inventory script added for Spacewalk / Red Hat Satellite servers
* It is now possible to feed JSON structures to --extra-vars.  Pass in a JSON dictionary/hash to feed in complex data.
* group_vars/ and host_vars/ directories can now be kept alongside the playbook as well as inventory (or both!)
* more filters: ability to say {{ foo|success }} and {{ foo|failed }} and when: foo|success and when: foo|failed
* more filters: {{ path|basename }} and {{ path|dirname }}
* lookup plugins now use the basedir of the file they have included from, avoiding needs of ../../../ in places and
increasing the ease at which things can be reorganized.
