+Synapse 1.15.0rc1 (2020-06-09)
+==============================
 
-* 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.
+Features
+--------
 
-* 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.

+
+Synapse 1.13.0 (2020-05-19)
+===========================
+
+This release brings some potential changes necessary for certain
+configurations of Synapse:
+
+* 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`.
+
+
+Internal Changes

 ## How to contribute

-your changes into our repo.

-**The single biggest thing you need to know is: please base your changes on
-the develop branch - *not* master.**
+Some other points to follow:
+ 
+ * Please base your changes on the `develop` branch.
+  
+ * Please follow the [code style requirements](#code-style).
 
-We use the master branch to track the most recent release, so that folks who
-blindly clone the repo and automatically check out master get something that
-works. Develop is the unstable branch where all the development actually
-happens: the workflow is that contributors should fork the develop branch to
-make a 'feature' branch for a particular contribution, and then make a pull
-request to merge this back into the matrix.org 'official' develop branch. We
-use github's pull request workflow to review the contribution, and either ask
-you to make any refinements needed or merge it and make them ourselves. The
-changes will then land on master when we next do a release.
+ * Please include a [changelog entry](#changelog) with each PR.
 
-We use [Buildkite](https://buildkite.com/matrix-dot-org/synapse) for continuous
-integration. If your change breaks the build, this will be shown in GitHub, so
-please keep an eye on the pull request for feedback.
+ * Please [sign off](#sign-off) your contribution.

+Obviously, you don't know if you should call your newsfile

+chicken-and-egg problem.
+
+There are two options for solving this:

+    add the changelog file to your branch (see [Updating your pull
+    request](#updating-your-pull-request)), or:

+ 1. Look at the [list of all

+[Buildkite](https://buildkite.com/matrix-dot-org/synapse) will automatically
+run a series of checks and tests against any PR which is opened against the

-We aim to have a clean merge history, which means we normally squash-merge

-to clean up your PR before merging. Larger changes with an organised set of
-commits may be merged as-is, if the history is judged to be useful.
+To run unit tests in a local development environment, you can use:

+## Updating your pull request
+
+If you decide to make changes to your pull request - perhaps to address issues
+raised in a review, or to fix problems highlighted by [continuous
+integration](#continuous-integration-and-testing) - just add new commits to your
+branch, and push to GitHub. The pull request will automatically be updated.

+Please **avoid** rebasing your branch, especially once the PR has been
+reviewed: doing so makes it very difficult for a reviewer to see what has
+changed since a previous review.

+``sso_account_deactivated.html``) were added to Synapse. If your Synapse is
