+Release Notes
+=============
+
+What are release notes?
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Release notes are important for change management within manila. Since manila
+follows a release cycle with milestones, release notes provide a way for the
+community and users to quickly grasp what changes occurred within a development
+milestone. To the OpenStack release management and documentation teams,
+release notes are a way to compile changes per milestone. These notes are
+published on the `OpenStack Releases website <http://releases.openstack.org>`_.
+Automated tooling is built around ``releasenotes`` and they get appropriately
+handled per release milestone, including any back-ports to stable releases.
+
+What needs a release note?
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+* Changes that impact an upgrade, most importantly, those that require a
+  deployer to take some action while upgrading
+
+* A new feature is implemented
+* An existing feature is deprecated
+* An existing feature is removed
+* Behavior of an existing feature has changed in a discernible way to an end
+  user or administrator
+* A security bug is fixed
+* New configuration option is added
+
+What does not need a release note?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+* A code change that doesn't change the general behavior of any
+  feature such as code refactor or logging changes.
+* Functional or unit test coverage enhancement
+* Changes to the content of an error message displayed on the UI
+* Any change submitted with a justified TrivialFix flag added in the commit
+  message
+* Adding or changing documentation within in-tree documentation guides
+
+How do I add a release note?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+We use `Reno <https://docs.openstack.org/reno/latest/>`_ to create and manage
+release notes. The new subcommand combines a random suffix with a "slug" value
+to make the new file with a unique name that is easy to identify again later.
+To create a release note for your change, use:
+
+.. code-block:: console
+
+    $ reno new slug-goes-here
+
+If reno is not installed globally on your system, you can use a tox
+environment in manila:
+
+.. code-block:: console
+
+    $ tox -e newnote slug-goes-here
+
+.. note::
+
+    When you are adding a bug-fix reno, name your file using the template:
+    "bug-<launchpad-bug-id>-slug-goes-here".
+
+Then add the notes in ``yaml`` format in the file created. Pay attention to the
+type of section. The following are general sections to use:
+
+prelude
+
+  General comments about the change. The prelude from all notes in a
+  release are combined, in note order, to produce a single prelude
+  introducing the release.
+
+features
+
+  New features introduced
+
+issues
+
+  A list of known issues with respect to the change being introduced. For
+  example, if the new feature in the change is experimental or known to not
+  work in some cases, it should be mentioned here.
+
+upgrade
+
+  A list of upgrade notes in the release. Any removals that affect upgrades are
+  to be noted here.
+
+deprecations
+
+  Any features, APIs, configuration options that the change has deprecated.
+  Deprecations are not removals. Deprecations suggest that there will be
+  support for a certain timeline. Deprecation should allow time for users
+  to make necessary changes for the removal to happen in a future release.
+  It is important to note the timeline of deprecation in this section.
+
+critical
+
+  A list of *fixed* critical bugs (descriptions only).
+
+security
+
+  A list of *fixed* security issues (descriptions only).
+
+fixes
+
+  A list of other *fixed* bugs (descriptions only).
+
+other
+
+  Other notes that are important but do not fall into any of the given
+  categories.
+
+::
+
+   ---
+   prelude: >
+       Replace this text with content to appear at the
+       top of the section for this change.
+   features:
+     - List new features here, or remove this section.
+   issues:
+     - List known issues here, or remove this section.
+   upgrade:
+     - List upgrade notes here, or remove this section.
+   deprecations:
+     - List deprecation notes here, or remove this section
+   critical:
+     - Add critical notes here, or remove this section.
+   security:
+     - Add security notes here, or remove this section.
+   fixes:
+     - Add normal bug fixes here, or remove this section.
+   other:
+     - Add other notes here, or remove this section.
+
+
+Dos and Don'ts
+~~~~~~~~~~~~~~
+* Release notes need to be succinct. Short and unambiguous descriptions are
+  preferred
+* Write in past tense, unless you are writing an imperative statement
+* Do not have blank sections in the file
+* Do not include code or links
+* Avoid special rst formatting unless absolutely necessary
+* Always prefer including a release note in the same patch
+* Release notes are not a replacement for developer/user/admin documentation
+* Release notes are not a way of conveying behavior of any features or usage of
+  any APIs
+* Limit a release note to fewer than 2-3 lines per change per section
+* OpenStack prefers atomic changes. So remember that your change may need the
+  fewest sections possible
+* General writing guidelines can be found
+  `here <https://docs.openstack
+  .org/doc-contrib-guide/writing-style/general-writing-guidelines.html>`_
+* Proofread your note. Pretend you are a user or a deployer who is reading
+  the note after a milestone or a release has been cut
+
+Examples
+~~~~~~~~
+
+The following need only be considered as directions for formatting. They
+are **not** fixes or features in manila.
+
+
+* *add-share-network-create-workflows-41cad17c1498a3.yaml*
+
+.. code-block:: yaml
+
+    ---
+    features:
+     - switched share network creation into two-step workflows.
