+Synapse 1.18.0 (2020-07-30)
+===========================
+
+Deprecation Warnings
+--------------------
+
+### Docker Tags with `-py3` Suffix
+
+From 10th August 2020, we will no longer publish Docker images with the `-py3` tag suffix. The images tagged with the `-py3` suffix have been identical to the non-suffixed tags since release 0.99.0, and the suffix is obsolete.
+
+On 10th August, we will remove the `latest-py3` tag. Existing per-release tags (such as `v1.18.0-py3`) will not be removed, but no new `-py3` tags will be added.
+
+Scripts relying on the `-py3` suffix will need to be updated.
+
+
+### TCP-based Replication
+
+When setting up worker processes, we now recommend the use of a Redis server for replication. The old direct TCP connection method is deprecated and will be removed in a future release. See [docs/workers.md](https://github.com/matrix-org/synapse/blob/release-v1.18.0/docs/workers.md) for more details.

+# Picking a database engine
+
+Synapse offers two database engines:
+ * [PostgreSQL](https://www.postgresql.org)
+ * [SQLite](https://sqlite.org/)
+
+Almost all installations should opt to use PostgreSQL. Advantages include:
+
+* significant performance improvements due to the superior threading and
+  caching model, smarter query optimiser
+* allowing the DB to be run on separate hardware
+
+For information on how to install and use PostgreSQL, please see
+[docs/postgres.md](docs/postgres.md)
+
+By default Synapse uses SQLite and in doing so trades performance for convenience.
+SQLite is only recommended in Synapse for testing purposes or for servers with
+light workloads.

+## Client Well-Known URI
+
+Setting up the client Well-Known URI is optional but if you set it up, it will
+allow users to enter their full username (e.g. `@user:<server_name>`) into clients
+which support well-known lookup to automatically configure the homeserver and
+identity server URLs. This is useful so that users don't have to memorize or think
+about the actual homeserver URL you are using.
+
+The URL `https://<server_name>/.well-known/matrix/client` should return JSON in
+the following format.
+
+```
+{
+  "m.homeserver": {
+    "base_url": "https://<matrix.example.com>"

+To work in browser based clients, the file must be served with the appropriate
+Cross-Origin Resource Sharing (CORS) headers. A recommended value would be
+`Access-Control-Allow-Origin: *` which would allow all browser based clients to

+In nginx this would be something like:

+    add_header Content-Type application/json;
+    add_header Access-Control-Allow-Origin *;
+}
+```
+
+You should also ensure the `public_baseurl` option in `homeserver.yaml` is set
+correctly. `public_baseurl` should be set to the URL that clients will use to
+connect to your server. This is the same URL you put for the `m.homeserver`
