v1.71.0

Synapse 1.71.0 (2022-11-08)

Please note that, as announced in the release notes for Synapse 1.69.0, legacy Prometheus metric names are now disabled by default.
They will be removed altogether in Synapse 1.73.0.
If not already done, server administrators should update their dashboards and alerting rules to avoid using the deprecated metric names.
See the upgrade notes for more details.

Note: in line with our deprecation policy for platform dependencies, this will be the last release to support PostgreSQL 10, which reaches upstream end-of-life on November 10th, 2022. Future releases of Synapse will require PostgreSQL 11+.

This release fixes some regressions that were discovered in 1.70.0.

#14300 was previously reported to be a regression in 1.70.0 as well. However, we have since concluded that it was limited to the reporter and thus have not needed to include any fix for it in 1.70.1.

Bugfixes

• Fix a bug introduced in Synapse 1.70.0rc1 where the access tokens sent to application services as headers were malformed. Application services which were obtaining access tokens from query parameters were not affected. (#14301)

v1.69.0

Synapse 1.69.0 (2022-10-17)

Please note that legacy Prometheus metric names are now deprecated and will be removed in Synapse 1.73.0.
Server administrators should update their dashboards and alerting rules to avoid using the deprecated metric names.
See the upgrade notes for more details.

No significant changes since 1.69.0rc4.
