([\#4164](https://github.com/matrix-org/synapse/issues/4164)) Deprecations and Removals ------------------------- - The disused and un-specced identicon generator has been removed. ([\#4106](https://github.com/matrix-org/synapse/issues/4106)) - The obsolete and non-functional /pull federation endpoint has been removed. ([\#4118](https://github.com/matrix-org/synapse/issues/4118)) - The deprecated v1 key exchange endpoints have been removed. ([\#4119](https://github.com/matrix-org/synapse/issues/4119)) - Synapse will no longer fetch keys using the fallback deprecated v1 key exchange method and will now always use v2. ([\#4120](https://github.com/matrix-org/synapse/issues/4120)) Internal Changes ---------------- - Fix build of Docker image with docker-compose ([\#3778](https://github.com/matrix-org/synapse/issues/3778)) - Delete unreferenced state groups during history purge ([\#4006](https://github.com/matrix-org/synapse/issues/4006)) - The "Received rdata" log messages on workers is now logged at DEBUG, not INFO.
