# Working with Release Notes

The Keystone team uses reno to generate release notes. These are important user-facing documents that must be included when a user or operator facing change is performed, like a bug-fix or a new feature. A release note should be included in the same patch the work is being performed. Release notes should be short, easy to read, and easy to maintain. They also must link back to any appropriate documentation if it exists. The following conventions help ensure all release notes achieve those goals.

Most release notes either describe bug fixes or announce support for new features, both of which are tracked using Launchpad. The conventions below rely on links in Launchpad to provide readers with more context.

Warning

We highly recommend taking careful thought when writing and reviewing release notes. Once a release note has been published with a formal release, updating it across releases will cause it to be published in a subsequent release. Reviews that update, or modify, a release note from a previous release outside of the branch it was added in should be rejected unless it’s required for a very specific case.

Please refer to reno’s documentation for more information.

## Release Notes for Bugs

When creating a release note that communicates a bug fix, use the bug number in the name of the release note:

    $ reno new bug-1652012
    Created new notes file in releasenotes/notes/bug-1652012-7c53b9702b10084d.yaml

The body of the release note should clearly explain how the impact will affect users and operators. It should also include why the change was necessary but not be overspecific about implementation details, as that can be found in the commit and the bug report. It should contain a properly formatted link in reStructuredText that points back to the original bug report used to track the fix. This ensures the release note is kept short and to-the-point while providing readers with additional resources:

    ---
    fixes:
      - |
        [`bug 1652012 <https://bugs.launchpad.net/keystone/+bug/1652012>`_]
        Changes the token_model to return is_admin_project False if the
        attribute is not defined. Returning True for this has the potential to
        be dangerous and the given reason for keeping it True was strictly for
        backwards compatibility.

## Release Notes for Features

Release notes detailing feature work follow the same basic format, since features are also tracked as bugs.

    $ reno new bug-1652012
    Created new notes file in releasenotes/notes/bug-1652012-7c53b9702b10084d.yaml

Just like release notes communicating bug fixes, release notes detailing feature work must contain a link back to the RFE bug report. Readers should be able to easily discover all patches that implement the feature, as well as find links to the full specification and documentation. The release notes can be added to the last patch of the feature. All of this is typically found in the RFE bug report registered in Launchpad:

    ---
    features:
      - >
        [`bug 1652012 <https://bugs.launchpad.net/keystone/+bug/1652012>`_]
        Keystone now fully supports the usage of fizzbangs.

In the rare case there is a release note that does not pertain to a bug or feature work, use a sensible slug and include any documentation relating to the note. We can iterate on the content and application of the release note during the review process.
