Update changelog based on feedback.

Fix a bug where the `get_joined_users` cache could be corrupted by custom
status events (or other state events with a state_key matching the user ID).

The bug was introduced by #2229, but has largely gone unnoticed since then.

Fixes #7099, #7373.

-Next version
-============
+Synapse 1.13.0 (2020-05-19)
+===========================
 
-* New templates (`sso_auth_confirm.html`, `sso_auth_success.html`, and
- `sso_account_deactivated.html`) were added to Synapse. If your Synapse is
- configured to use SSO and a custom  `sso_redirect_confirm_template_dir`
- configuration then these templates will need to be duplicated into that
- directory.
+This release brings some potential changes necessary for certain
+configurations of Synapse:
 
-* Plugins using the `complete_sso_login` method of `synapse.module_api.ModuleApi`
-  should update to using the async/await version `complete_sso_login_async` which
-  includes additional checks. The non-async version is considered deprecated.
+* If your Synapse is configured to use SSO and have a custom
+  `sso_redirect_confirm_template_dir` configuration option set, you will need
+  to duplicate the new `sso_auth_confirm.html`, `sso_auth_success.html` and
+  `sso_account_deactivated.html` templates into that directory.
+* Synapse plugins using the `complete_sso_login` method of
+  `synapse.module_api.ModuleApi` should instead switch to the async/await
+  version, `complete_sso_login_async`, which includes additional checks. The
+  former version is now deprecated.
+* A bug was introduced in Synapse 1.4.0 which could cause the room directory
+  to be incomplete or empty if Synapse was upgraded directly from v1.2.1 or
+  earlier, to versions between v1.4.0 and v1.12.x.
+
+Please review [UPGRADE.rst](UPGRADE.rst) for more details on these changes
+and for general upgrade guidance.
+
+
+Notice of change to the default `git` branch for Synapse
+--------------------------------------------------------
+
+With the release of Synapse 1.13.0, the default `git` branch for Synapse has
+changed to `develop`, which is the development tip. This is more consistent with
+common practice and modern `git` usage.
+
+The `master` branch, which tracks the latest release, is still available. It is
+recommended that developers and distributors who have scripts which run builds
+using the default branch of Synapse should therefore consider pinning their
+scripts to `master`.
+

+Upgrading to v1.13.0
+====================
+
+
+Incorrect database migration in old synapse versions
+----------------------------------------------------
+
+A bug was introduced in Synapse 1.4.0 which could cause the room directory to
+be incomplete or empty if Synapse was upgraded directly from v1.2.1 or
+earlier, to versions between v1.4.0 and v1.12.x.
+
+This will *not* be a problem for Synapse installations which were:
+ * created at v1.4.0 or later,
+ * upgraded via v1.3.x, or
+ * upgraded straight from v1.2.1 or earlier to v1.13.0 or later.
+
+If completeness of the room directory is a concern, installations which are
+affected can be repaired as follows:
+
+1. Run the following sql from a `psql` or `sqlite3` console:
+
+   .. code:: sql
+
+     INSERT INTO background_updates (update_name, progress_json, depends_on) VALUES
+        ('populate_stats_process_rooms', '{}', 'current_state_events_membership');
+
+     INSERT INTO background_updates (update_name, progress_json, depends_on) VALUES
+        ('populate_stats_process_users', '{}', 'populate_stats_process_rooms');
+
+2. Restart synapse.
+
+New Single Sign-on HTML Templates
+---------------------------------
+
+New templates (``sso_auth_confirm.html``, ``sso_auth_success.html``, and
+``sso_account_deactivated.html``) were added to Synapse. If your Synapse is
+configured to use SSO and a custom  ``sso_redirect_confirm_template_dir``
+configuration then these templates will need to be copied from
+`synapse/res/templates <synapse/res/templates>`_ into that directory.
+
+Synapse SSO Plugins Method Deprecation
+--------------------------------------
+
+Plugins using the ``complete_sso_login`` method of
+``synapse.module_api.ModuleApi`` should update to using the async/await
+version ``complete_sso_login_async`` which includes additional checks. The
+non-async version is considered deprecated.
+
+Rolling back to v1.12.4 after a failed upgrade
+----------------------------------------------
+
+v1.13.0 includes a lot of large changes. If something problematic occurs, you
+may want to roll-back to a previous version of Synapse. Because v1.13.0 also
+includes a new database schema version, reverting that version is also required
+alongside the generic rollback instructions mentioned above. In short, to roll
+back to v1.12.4 you need to:
+
+1. Stop the server
+2. Decrease the schema version in the database:
+
+   .. code:: sql
+    
+      UPDATE schema_version SET version = 57;
+
+3. Downgrade Synapse by following the instructions for your installation method
+   in the "Rolling back to older versions" section above.
+    
+
 Upgrading to v1.12.0
