Releasing collections with release branches
============================================

Collections MUST follow the `semantic versioning <https://semver.org/>`_ rules. See :ref:`releasing_collections` for high-level details.

Release planning and announcement
----------------------------------

#. Announce your intention to release the collection in a corresponding pinned release issue/community pinboard of the collection and in the ``#ansible-community`` `Matrix/IRC channel <https://docs.ansible.com/ansible/devel/community/communication.html#real-time-chat>`_. Repeat the announcement in any other dedicated channels if they exist.

#. Ensure all the other repository maintainers are informed about the time of the following release.


Releasing major collection versions
-------------------------------------

The new version is assumed to be ``X.0.0``.

1. If you are going to release the ``community.general`` and ``community.network`` collections, create new ``backport-X`` and ``needs_backport_to_stable_X`` labels in the corresponding repositories. Copy the styles and descriptions from the corresponding existing labels.

2. Ensure you are in a default branch in your local fork. These examples use ``main``.

  .. code-block:: bash

    git status
    git checkout main     # if needed


3. Update your local fork:

  .. code-block:: bash

    git pull --rebase upstream main


Creating the release branch
^^^^^^^^^^^^^^^^^^^^^^^^^^^^

1. Create a branch ``stable-X``. Replace ``X`` with a correct number and push it to the **upstream** repository, NOT to the ``origin``.:

  .. code-block:: bash

    git branch stable-X main
    git push upstream stable-X


2. Create and checkout to another branch from the ``main`` branch:

  .. code-block:: bash

    git checkout -b update_repo


3. Update the version in ``galaxy.yml`` in the branch to the next **expected** version, for example, ``X.1.0``.


Creating the changelogs
^^^^^^^^^^^^^^^^^^^^^^^^

1. Replace ``changelogs/changelog.yml`` with:

  .. code-block:: yaml

    ancestor: X.0.0
    releases: {}


2. Remove all changelog fragments from ``changelogs/fragments/``. Removing the changelog fragments ensures that every major release has a changelog describing changes since the last major release.

3. Add and commit all the changes made. Push the branch to the ``origin`` repository.

4. Create a pull request in the collection repository. If CI tests pass, merge the pull request since the ``main`` branch is expecting changes for the next minor/major versions

5. Switch to the ``stable-X`` branch.

6. In the ``stable-X`` branch, ensure that ``galaxy.yml`` contains the correct version number ``X.0.0``. If not, update it.

7. In the ``stable-X`` branch, add a changelog fragment ``changelogs/fragments/X.0.0.yml`` with the content:

  .. code-block:: yaml

    release_summary: |-
      Write some text here that should appear as the release summary for this version.
      The format is reStructuredText, but not a list as for regular changelog fragments.
      This text will be inserted into the changelog.

  For example:

  .. code-block:: yaml

    release_summary: This is release 2.0.0 of ``community.foo``, released on YYYY-MM-DD.


8. In the ``stable-X`` branch, generate the changelogs:

  .. code-block:: bash

    antsibull-changelog release --cummulative-release


9. In the ``stable-X`` branch, verify that the ``CHANGELOG.rst`` looks as expected.

10. In the ``stable-X`` branch, update ``README.md`` so that the changelog link points to ``/tree/stable-X/`` and no longer to ``/tree/main/``, and change badges respectively, for example, in case of AZP, add ``?branchName=stable-X`` to the AZP CI badge (https://dev.azure.com/ansible/community.xxx/_apis/build/status/CI?branchName=stable-X).

11. In the ``stable-X`` branch, add, commit, and push changes to ``README.md``, ``CHANGELOG.rst`` and ``changelogs/changelog.yaml``, and potentially deleted/archived fragments to the **upstream** repository, NOT to the ``origin``.


Publishing the collection
^^^^^^^^^^^^^^^^^^^^^^^^^^

1. In the ``stable-X`` branch, add an annotated tag to the last commit with the collection version ``X.0.0``. Pushing this tag to the ``upstream`` repository will make Zuul publish the collection on `Ansible Galaxy <https://galaxy.ansible.com/>`_.

  .. code-block:: bash

    git tag -n    # see current tags and their comments
    git tag -a NEW_VERSION -m "comment here"    # the comment can be, for example, "community.foo: 2.0.0"
    git push upstream NEW_VERSION


2. Wait until the new version is published on the collection's `Ansible Galaxy <https://galaxy.ansible.com/>`_ page. It will appear in a list of tarballs available to download.

3. Add a GitHub release for the new tag. The title should be the version and content, such as -  ``See https://github.com/ansible-collections/community.xxx/blob/stable-X/CHANGELOG.rst for all changes``.


4. Announce the release through the `Bullhorn Newsletter <https://github.com/ansible/community/wiki/News#the-bullhorn>`_.

5. Announce the release in the pinned release issue/community pinboard of the collection and in the ``#ansible-community`` `Matrix/Libera.Chat IRC channel <https://docs.ansible.com/ansible/devel/community/communication.html#real-time-chat>`_.

6. In the ``stable-X`` branch, update the version in ``galaxy.yml`` to the next **expected** version, for example, ``X.1.0``. Add, commit and push to the **upstream** repository.


Releasing minor collection versions
-------------------------------------

The new version is assumed to be ``X.Y.0``. All changes that should go into it are expected to be previously backported from the default branch to the ``stable-X`` branch.

Creating the changelogs
^^^^^^^^^^^^^^^^^^^^^^^^

1. In the ``stable-X`` branch, make sure that ``galaxy.yml`` contains the correct version number ``X.Y.0``. If not, update it.

2. In the ``stable-X`` branch, add a changelog fragment ``changelogs/fragments/X.Y.0.yml`` with content:

  .. code-block:: yaml

    release_summary: |-
      Write some text here that should appear as the release summary for this version.
      The format is reStructuredText, but not a list as for regular changelog fragments.
      This text will be inserted into the changelog.


3. In the ``stable-X`` branch, run:

  .. code-block:: bash

   antsibull-changelog release


4. In the ``stable-X`` branch, verify that ``CHANGELOG.rst`` looks as expected.

5. In the ``stable-X`` branch, add, commit, and push changes to ``CHANGELOG.rst`` and ``changelogs/changelog.yaml``, and potentially deleted/archived fragments to the **upstream** repository, NOT to the origin.


Publishing the collection
^^^^^^^^^^^^^^^^^^^^^^^^^^

1. In the ``stable-X`` branch, add an annotated tag to the last commit with the collection version ``X.Y.0``. Pushing this tag to the ``upstream`` repository will make Zuul publish the collection on `Ansible Galaxy <https://galaxy.ansible.com/>`_.

  .. code-block:: bash

   git tag -n    # see current tags and their comments
   git tag -a NEW_VERSION -m "comment here"    # the comment can be, for example, "community.foo: 2.1.0"
   git push upstream NEW_VERSION


2. Wait until the new version is published on the collection's `Ansible Galaxy <https://galaxy.ansible.com/>`_ page. The published version will appear in a list of tarballs available to download.

3. Add a GitHub release for the new tag. The title should be the version and content, such as -  ``See https://github.com/ansible-collections/community.xxx/blob/stable-X/CHANGELOG.rst for all changes``.

4. Announce the release through the `Bullhorn Newsletter <https://github.com/ansible/community/wiki/News#the-bullhorn>`_.

5. Announce the release in the pinned release issue/community pinboard of the collection and in the ``#ansible-community`` `Matrix/IRC channel <https://docs.ansible.com/ansible/devel/community/communication.html#real-time-chat>`_. Additionally, you can announce it using GitHub's Releases system.

6. In the ``stable-X`` branch, update the version in ``galaxy.yml`` to the next **expected** version, for example, if you have released ``X.1.0``, the next expected version could be ``X.2.0``. Add, commit and push to the **upstream** repository.

7. Checkout to the ``main`` branch.

8. In the ``main`` branch:

  #. If more minor versions are released before the next major version, update the version in ``galaxy.yml`` to ``X.(Y+1).0`` as well. Create a dedicated pull request and merge.

  #. If the next version will be a new major version, create a pull request where you update the version in ``galaxy.yml`` to ``(X+1).0.0``. Note that the sanity tests will most likely fail since there will be deprecations with removal scheduled for ``(X+1).0.0``, which are flagged by the tests.

  For every such deprecation, decide:
  
  * Whether to remove them now. For example you remove the complete ``modules/plugins`` or you remove redirects. 
  * Whether to add ignore entries to the corresponding ``tests/sanity/ignore-*.txt`` file and create issues, for example for removed features in ``modules/plugins``.

  Once the CI tests pass, merge the pull request. Make sure that this pull request is merged not too much later after the release
  for ``version_added`` sanity tests not to expect the wrong version for the new feature pull request.

.. note::

  It makes sense to already do some removals in the days before the release. These removals must happen in the main branch and must not be backported.


Releasing patch versions
-------------------------

The new version is assumed to be ``X.Y.Z``, and the previous patch version is assumed to be ``X.Y.z`` with ``z < Z``.  ``z`` is frequently``0`` since patch releases are uncommon.

Releasing when more minor versions are expected
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

1. Checkout the ``X.Y.z`` tag.

2. Update ``galaxy.yml`` so that the version is ``X.Y.Z``. Add and commit.

3. Cherry-pick all changes from ``stable-X`` that were added after ``X.Y.z`` and should go into ``X.Y.Z``.

4. Add a changelog fragment ``changelogs/fragments/X.Y.Z.yml`` with content:

  .. code-block:: yaml

    release_summary: |-
      Write some text here that should appear as the release summary for this version.
      The format is reStructuredText but not a list as for regular changelog fragments.
      This text will be inserted into the changelog.

  Add to git and commit.

5. Generate the changelogs.

.. code-block:: bash

   antsibull-changelog release

6. Verify that ``CHANGELOG.rst`` looks as expected.

7. Add and commit changes to ``CHANGELOG.rst`` and ``changelogs/changelog.yaml``, and potentially deleted/archived fragments.

**Publishing the collection**


1. Add an annotated tag to the last commit with the collection version ``X.Y.Z``. Pushing this tag to the ``upstream`` repository will make Zuul publish the collection on `Ansible Galaxy <https://galaxy.ansible.com/>`_.

  .. code-block:: bash

   git tag -n    # see current tags and their comments
   git tag -a NEW_VERSION -m "comment here"    # the comment can be, for example, "community.foo: 2.1.1"
   git push upstream NEW_VERSION


2. Wait until the new version is published on the collection's `Ansible Galaxy <https://galaxy.ansible.com/>`_ page. It will appear in a list of tarballs available to download.

3. Add a GitHub release for the new tag. The title should be the version and content, such as - ``See https://github.com/ansible-collections/community.xxx/blob/stable-X/CHANGELOG.rst for all changes``.

  .. note::

    The data for this release is only contained in a tag, and not in a branch, in particular not in ``stable-X``.
    This is deliberate, since the next minor release ``X.(Y+1).0`` already contains the changes for ``X.Y.Z`` as well, since these were cherry-picked from ``stable-X``.


4. Announce the release through the `Bullhorn Newsletter <https://github.com/ansible/community/wiki/News#the-bullhorn>`_.

5. Announce the release in the pinned release issue/community pinboard of the collection and in the ``#ansible-community`` `Matrix/IRC channel <https://docs.ansible.com/ansible/devel/community/communication.html#real-time-chat>`.


Releasing when no more minor versions are expected
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

1. In the ``stable-X`` branch, make sure that ``galaxy.yml`` contains the correct version number ``X.Y.Z``. If not, update it!

2. In the ``stable-X`` branch, add a changelog fragment ``changelogs/fragments/X.Y.Z.yml`` with content:

  .. code-block:: yaml

    release_summary: |-
      Write some text here that should appear as the release summary for this version.
      The format is reStructuredText, but not a list as for regular changelog fragments.
      This text will be inserted into the changelog.


3. Generate the changelogs in the ``stable-X`` branch.

  .. code-block:: bash

   antsibull-changelog release


4. In the ``stable-X`` branch, verify that ``CHANGELOG.rst`` looks as expected.

5. In the ``stable-X`` branch, add, commit, and push changes to ``CHANGELOG.rst`` and ``changelogs/changelog.yaml``, and potentially deleted/archived fragments to the **upstream** repository, NOT to the origin.
