Synapse 1.50.0 (2022-01-18)
===========================
+**This release contains a critical bug that may prevent clients from being able to connect.
+As such, it is not recommended to upgrade to 1.50.0. Instead, please upgrade straight to
+to 1.50.1. Further details are available in [this issue](https://github.com/matrix-org/synapse/issues/11763).**
+
Please note that we now only support Python 3.7+ and PostgreSQL 10+ (if applicable), because Python 3.6 and PostgreSQL 9.6 have reached end-of-life.
No significant changes since 1.50.0rc2.
