+Changelog fragments
+-------------------
 
 Changelogs help users and developers keep up with changes to ansible-core and Ansible collections. Ansible and many collections build changelogs for each release from fragments. For ansible-core and collections using this model, you **must** add a changelog fragment to any PR that changes functionality or fixes a bug.

 * New modules and plugins (including jinja2 filter and test plugins) must have ``version_added`` entries set correctly in their documentation, and do not need a changelog fragment. The tooling detects new modules and plugins by their ``version_added`` values and announces them in the next release's changelog automatically.

 Creating a changelog fragment
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-A basic changelog fragment is a ``.yaml`` or ``.yml`` file placed in the ``changelogs/fragments/`` directory.  Each file contains a yaml dict with keys like ``bugfixes`` or ``major_changes`` followed by a list of changelog entries of bugfixes or features.  Each changelog entry is rst embedded inside of the yaml file which means that certain constructs would need to be escaped so they can be interpreted by rst and not by yaml (or escaped for both yaml and rst if you prefer).  Each PR **must** use a new fragment file rather than adding to an existing one, so we can trace the change back to the PR that introduced it.

 PRs which add a new module or plugin do not necessarily need a changelog fragment. See the previous section :ref:`community_changelogs`. Also see the next section :ref:`changelogs_how_to_format` for the precise format changelog fragments should have.
