Synapse 1.14.0rc2 (2020-05-27)

==============================
 
 Bugfixes
 --------
 
 - Fix cache config to not apply cache factor to event cache. Regression in v1.14.0rc1. ([\#7578](https://github.com/matrix-org/synapse/issues/7578))
 - Fix bug where `ReplicationStreamer` was not always started when replication was enabled. Bug introduced in v1.14.0rc1. ([\#7579](https://github.com/matrix-org/synapse/issues/7579))
 - Fix specifying individual cache factors for caches with special characters in their name. Regression in v1.14.0rc1. ([\#7580](https://github.com/matrix-org/synapse/issues/7580))
 
 Improved Documentation
 ----------------------
 
 - Fix the OIDC `client_auth_method` value in the sample config. ([\#7581](https://github.com/matrix-org/synapse/issues/7581))
