Synapse 1.45.0rc2 (2021-10-14)
==============================

**Note:** This release candidate [fixes](#11053) the user directory [bug](#11025) present in 1.45.0rc1. However, the [performance issue](#11049) which appeared in v1.44.0 is yet to be resolved.

Bugfixes
--------

- Fix a long-standing bug when using multiple event persister workers where events were not correctly sent down `/sync` due to a race. ([\#11045](#11045))
- Fix a bug introduced in Synapse 1.45.0rc1 where the user directory would stop updating if it processed an event from a
  user not in the `users` table. ([\#11053](#11053))
- Fix a bug introduced in Synapse v1.44.0 when logging errors during oEmbed processing. ([\#11061](#11061))

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

- Add an 'approximate difference' method to `StateFilter`. ([\#10825](#10825))
- Fix inconsistent behavior of `get_last_client_by_ip` when reporting data that has not been stored in the database yet. ([\#10970](#10970))
- Fix a bug introduced in Synapse 1.21.0 that causes opentracing and Prometheus metrics for replication requests to be measured incorrectly. ([\#10996](#10996))
- Ensure that cache config tests do not share state. ([\#11036](#11036))
