Synapse 1.49.1 (2021-12-21)
===========================

This release fixes a regression introduced in Synapse 1.49.0 which could cause `/sync` requests to take significantly longer. This would particularly affect "initial" syncs for users participating in a large number of rooms, and in extreme cases, could make it impossible for such users to log in on a new client.

**Note:** in line with our [deprecation policy](https://matrix-org.github.io/synapse/latest/deprecation_policy.html) for platform dependencies, this will be the last release to support Python 3.6 and PostgreSQL 9.6, both of which have now reached upstream end-of-life. Synapse will require Python 3.7+ and PostgreSQL 10.

**Note:** We will also stop producing packages for Ubuntu 18.04 (Bionic Beaver) after this release, as it uses Python 3.6.
