Release cycle

|
|
|
|
Ansible is developed and released on a flexible 4 months release cycle.
|
|
This cycle can be extended in order to allow for larger changes to be properly
|
|
implemented and tested before a new release is made available.
|
|
|
|
Ansible has a graduated support structure that extends to three major releases.
|
|
For more information, read about the :ref: `_development_and_stable_versiona_maintenance_workflow` or see
|
|
the chart in :ref:`schedule` for the degrees to which current releases are supported.
|
|
|
|
.. note:: Support for three major releases began with Ansible-2.4. Ansible-2.3 and older versions
|
|
are only supported for two releases.
|
|
|
|
If you are using a release of Ansible that is no longer supported, we strongly
|
|
encourage you to upgrade as soon as possible in order to benefit from the
|
|
latest features and security fixes.
|
|
|
|
Older, unsupported versions of Ansible can contain unfixed security
|
|
vulnerabilities (*CVE*).
|
|
|
|
You can refer to the `porting guides`_ for tips on updating your Ansible
|
|
playbooks to run on newer versions.

The Ansible community develops and maintains Ansible on GitHub_.
|
|
|
|
New modules, plugins, features and bugfixes will always be integrated in what will become the next
|
|
major version of Ansible. This work is tracked on the ``devel`` git branch.
|
|
|
|
Ansible provides bugfixes and security improvements for the most recent major release. The previous
|
|
major release will only receive fixes for security issues and critical bugs. Ansible only applies
|
|
security fixes to releases which are two releases old. This work is tracked on the
|
|
``stable-<version>`` git branches.
|
|
|
|
.. note:: Support for three major releases began with Ansible-2.4. Ansible-2.3 and older versions
|
|
are only supported for two releases with the first stage including both security and general bug
|
|
fixes while the second stage includes security and critical bug fixes
|
|
|
|
The fixes that land in supported stable branches will eventually be released
|
|
as a new version when necessary.
|
|
|
|
For more information on the changes included in each new version, you can refer
|
|
to the changelog_, available on GitHub.
|
|
|
|
Note that while there are no guarantees for providing fixes for unsupported
|
|
releases of Ansible, there can sometimes be exceptions for critical issues.

Release candidates
|
|
~~~~~~~~~~~~~~~~~~
|
|
|
|
Before a new release or version of Ansible can be done, it will typically go
|
|
through a release candidate process.
|
|
|
|
This provides the Ansible community the opportunity to test Ansible and report
|
|
bugs or issues they might come across.
|
|
|
|
Ansible tags the first release candidate (``RC1``) which is usually scheduled
|
|
to last five business days. The final release is done if no major bugs or
|
|
issues are identified during this period.
|
|
|
|
If there are major problems with the first candidate, a second candidate will
|
|
be tagged (``RC2``) once the necessary fixes have landed.
|
|
This second candidate lasts for a shorter duration than the first.
|
|
If no problems have been reported after two business days, the final release is
|
|
done.
|
|
|
|
More release candidates can be tagged as required, so long as there are
|
|
bugs that the Ansible core maintainers consider should be fixed before the
|
|
final release.
|
|
|
|
.. _release_freezing:

|
Feature freeze
|
|
~~~~~~~~~~~~~~
|
|
|
|
While there is a pending release candidate, the focus of core developers and
|
|
maintainers will on fixes towards the release candidate.
|
|
|
|
Merging new features or fixes that are not related to the release candidate may
|
|
be delayed in order to allow the new release to be shipped as soon as possible.
