- Allow configuration of the path used for ACME account keys. ([\#5516](https://github.com/matrix-org/synapse/issues/5516), [\#5521](https://github.com/matrix-org/synapse/issues/5521), [\#5522](https://github.com/matrix-org/synapse/issues/5522))
- Add --data-dir and --open-private-ports options. ([\#5524](https://github.com/matrix-org/synapse/issues/5524))
- Split public rooms directory auth config in two settings, in order to manage client auth independently from the federation part of it. Obsoletes the "restrict_public_rooms_to_local_users" configuration setting. If "restrict_public_rooms_to_local_users" is set in the config, Synapse will act as if both new options are enabled, i.e. require authentication through the client API and deny federation requests. ([\#5534](https://github.com/matrix-org/synapse/issues/5534))
- Update docker image to use Python 3.7. ([\#5546](https://github.com/matrix-org/synapse/issues/5546))
- Increase default log level for docker image to INFO. It can still be changed by editing the generated log.config file. ([\#5547](https://github.com/matrix-org/synapse/issues/5547))
- The minimum TLS version used for outgoing federation requests can now be set with `federation_client_minimum_tls_version`. ([\#5550](https://github.com/matrix-org/synapse/issues/5550))
- Optimise devices changed query to not pull unnecessary rows from the database, reducing database load. ([\#5559](https://github.com/matrix-org/synapse/issues/5559))
- Update Docker image to deprecate the use of environment variables for configuration, and make the use of a static configuration the default. ([\#5561](https://github.com/matrix-org/synapse/issues/5561), [\#5562](https://github.com/matrix-org/synapse/issues/5562), [\#5566](https://github.com/matrix-org/synapse/issues/5566), [\#5567](https://github.com/matrix-org/synapse/issues/5567))

- Docker image: open the non-TLS port by default. ([\#5568](https://github.com/matrix-org/synapse/issues/5568))
- Add new metrics for number of forward extremities being persisted and number of state groups involved in resolution. ([\#5476](https://github.com/matrix-org/synapse/issues/5476))
Bugfixes
--------
- Fix bug processing incoming events over federation if call to `/get_missing_events` fails. ([\#5042](https://github.com/matrix-org/synapse/issues/5042))
