Synapse 1.32.1 (2021-04-21)
|
||||
===========================
|
||||
|
||||
This release fixes [a regression](https://github.com/matrix-org/synapse/issues/9853)
|
||||
in Synapse 1.32.0 that caused connected Prometheus instances to become unstable. If you
|
||||
ran Synapse 1.32.0 with Prometheus metrics, first upgrade to Synapse 1.32.1 and follow
|
||||
[these instructions](https://github.com/matrix-org/synapse/pull/9854#issuecomment-823472183)
|
||||
to clean up any excess writeahead logs.

||||
|
||||

|
||||

|
||||
