Synapse 0.99.1 (2019-02-14)
===========================

Features
--------

- Include m.room.encryption on invites by default ([\#3902](https://github.com/matrix-org/synapse/issues/3902))
- Federation OpenID listener resource can now be activated even if federation is disabled ([\#4420](https://github.com/matrix-org/synapse/issues/4420))
- Synapse's ACME support will now correctly reprovision a certificate that approaches its expiry while Synapse is running. ([\#4522](https://github.com/matrix-org/synapse/issues/4522))
- Add ability to update backup versions ([\#4580](https://github.com/matrix-org/synapse/issues/4580))
- Allow the "unavailable" presence status for /sync.
  This change makes Synapse compliant with r0.4.0 of the Client-Server specification. ([\#4592](https://github.com/matrix-org/synapse/issues/4592))
- There is no longer any need to specify `no_tls`: it is inferred from the absence of TLS listeners ([\#4613](https://github.com/matrix-org/synapse/issues/4613), [\#4615](https://github.com/matrix-org/synapse/issues/4615), [\#4617](https://github.com/matrix-org/synapse/issues/4617), [\#4636](https://github.com/matrix-org/synapse/issues/4636))
- The default configuration no longer requires TLS certificates. ([\#4614](https://github.com/matrix-org/synapse/issues/4614))

Bugfixes
--------

- Copy over room federation ability on room upgrade. ([\#4530](https://github.com/matrix-org/synapse/issues/4530))
- Fix noisy "twisted.internet.task.TaskStopped" errors in logs ([\#4546](https://github.com/matrix-org/synapse/issues/4546))
- Synapse is now tolerant of the `tls_fingerprints` option being None or not specified. ([\#4589](https://github.com/matrix-org/synapse/issues/4589))
- Fix 'no unique or exclusion constraint' error ([\#4591](https://github.com/matrix-org/synapse/issues/4591))
- Transfer Server ACLs on room upgrade. ([\#4608](https://github.com/matrix-org/synapse/issues/4608))
- Fix failure to start when not TLS certificate was given even if TLS was disabled. ([\#4618](https://github.com/matrix-org/synapse/issues/4618))

Internal Changes
----------------

- Change the user directory state query to use a filtered call to the db instead of a generic one. ([\#4462](https://github.com/matrix-org/synapse/issues/4462))
- Reject federation transactions if they include more than 50 PDUs or 100 EDUs. ([\#4513](https://github.com/matrix-org/synapse/issues/4513))
- Reduce duplication of ``synapse.app`` code. ([\#4567](https://github.com/matrix-org/synapse/issues/4567))
- Fix docker upload job to push -py2 images. ([\#4576](https://github.com/matrix-org/synapse/issues/4576))
- Add port configuration information to ACME instructions. ([\#4578](https://github.com/matrix-org/synapse/issues/4578))
- Update MSC1711 FAQ to calrify .well-known usage ([\#4584](https://github.com/matrix-org/synapse/issues/4584))
- Clean up default listener configuration ([\#4586](https://github.com/matrix-org/synapse/issues/4586))
- Clarifications for reverse proxy docs ([\#4607](https://github.com/matrix-org/synapse/issues/4607))
- Move ClientTLSOptionsFactory init out of `refresh_certificates` ([\#4611](https://github.com/matrix-org/synapse/issues/4611))
- Fail cleanly if listener config lacks a 'port' ([\#4616](https://github.com/matrix-org/synapse/issues/4616))
- Remove redundant entries from docker config ([\#4619](https://github.com/matrix-org/synapse/issues/4619))
- README updates ([\#4621](https://github.com/matrix-org/synapse/issues/4621))

+Using a reverse proxy with Synapse
+==================================
+
+It is recommended to put a reverse proxy such as
+`nginx <https://nginx.org/en/docs/http/ngx_http_proxy_module.html>`_,
+`Apache <https://httpd.apache.org/docs/current/mod/mod_proxy_http.html>`_,
+`Caddy <https://caddyserver.com/docs/proxy>`_ or
+`HAProxy <https://www.haproxy.org/>`_ in front of Synapse. One advantage of
+doing so is that it means that you can expose the default https port (443) to
+Matrix clients without needing to run Synapse with root privileges.
+
+**NOTE**: Your reverse proxy must not 'canonicalise' or 'normalise' the
+requested URI in any way (for example, by decoding ``%xx`` escapes). Beware
+that Apache *will* canonicalise URIs unless you specifify ``nocanon``.
+
+When setting up a reverse proxy, remember that Matrix clients and other Matrix
+servers do not necessarily need to connect to your server via the same server
+name or port. Indeed, clients will use port 443 by default, whereas servers
+default to port 8448. Where these are different, we refer to the 'client port'
+and the 'federation port'. See `Setting up federation
+<../README.rst#setting-up-federation>`_ for more details of the algorithm used for
+federation connections.
+
+Let's assume that we expect clients to connect to our server at
+``https://matrix.example.com``, and other servers to connect at
+``https://example.com:8448``. Here are some example configurations:
+
+* nginx::
+
+      server {
+          listen 443 ssl;
+          listen [::]:443 ssl;
+          server_name matrix.example.com;
+
+          location /_matrix {
+              proxy_pass http://localhost:8008;
+              proxy_set_header X-Forwarded-For $remote_addr;
+          }
+      }
+
+      server {
+          listen 8448 ssl default_server;
+          listen [::]:8448 ssl default_server;
+          server_name example.com;
+
+          location / {
+              proxy_pass http://localhost:8008;
+              proxy_set_header X-Forwarded-For $remote_addr;
+          }
+      }
+
+* Caddy::
+
+      matrix.example.com {
+        proxy /_matrix http://localhost:8008 {
+          transparent
+        }
+      }
+
+      example.com:8448 {
+        proxy / http://localhost:8008 {
+          transparent
+        }
+      }
+
+* Apache (note the ``nocanon`` options here!)::
+
+      <VirtualHost *:443>
+          SSLEngine on
+          ServerName matrix.example.com;
+
+          <Location /_matrix>
+              ProxyPass http://127.0.0.1:8008/_matrix nocanon
+              ProxyPassReverse http://127.0.0.1:8008/_matrix
+          </Location>
+      </VirtualHost>
+
+      <VirtualHost *:8448>
+          SSLEngine on
+          ServerName example.com;
+
+          <Location />
+              ProxyPass http://127.0.0.1:8008/_matrix nocanon
+              ProxyPassReverse http://127.0.0.1:8008/_matrix
+          </Location>
+      </VirtualHost>
+
+You will also want to set ``bind_addresses: ['127.0.0.1']`` and ``x_forwarded: true``
+for port 8008 in ``homeserver.yaml`` to ensure that client IP addresses are
+recorded correctly.
+
+Having done so, you can then use ``https://matrix.example.com`` (instead of
+``https://matrix.example.com:8448``) as the "Custom server" when connecting to
+Synapse from a client.
