Bugfixes
--------

- Fix exceptions when using the email mailer on Python 3. ([\#4095](https://github.com/matrix-org/synapse/issues/4095))

- fix return code of empty key backups ([\#4123](https://github.com/matrix-org/synapse/issues/4123))
- If the typing stream ID goes backwards (as on a worker when the master restarts), the worker's typing handler will no longer erroneously report rooms containing new
typing events. ([\#4127](https://github.com/matrix-org/synapse/issues/4127))
- Fix table lock of device_lists_remote_cache which could freeze the application ([\#4132](https://github.com/matrix-org/synapse/issues/4132))
- Fix exception when using state res v2 algorithm ([\#4135](https://github.com/matrix-org/synapse/issues/4135))

[\#4163](https://github.com/matrix-org/synapse/issues/4163))
- Loading URL previews from the DB cache on Postgres will no longer cause Unicode type errors when responding to the request, and URL previews will no longer fail if
the remote server returns a Content-Type header with the chartype in quotes. ([\#4157](https://github.com/matrix-org/synapse/issues/4157))
- The hash_password script now works on Python 3. ([\#4161](https://github.com/matrix-org/synapse/issues/4161))
- Fix noop checks when updating device keys, reducing spurious device list update notifications. ([\#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

- Add STATE_V2_TEST room version ([\#4128](https://github.com/matrix-org/synapse/issues/4128))
- Clean up event accesses and tests ([\#4137](https://github.com/matrix-org/synapse/issues/4137))
- The default logging config will now set an explicit log file encoding of UTF-8. ([\#4138](https://github.com/matrix-org/synapse/issues/4138))
- Add helpers functions for getting prev and auth events of an event ([\#4139](https://github.com/matrix-org/synapse/issues/4139))
