Synapse 1.32.1 (2021-04-21)

This release fixes a regression in Synapse 1.32.0 that caused connected Prometheus instances to become unstable. If you ran Synapse 1.32.0 with Prometheus metrics, first downgrade to Synapse 1.31.0 and follow these instructions to clean up any excess writeahead logs.

However, as this release is additionally subject to a backwards-incompatible LoggingContext change in 1.32.0, it is recommended to continue to remain on or downgrade to 1.31.0.
