Synapse 1.142.0rc4 (2025-11-07)

Dropped support for Python 3.9

This release drops support for Python 3.9, in line with our dependency deprecation policy, as it is now end of life.

SQLite 3.40.0+ is now required

The minimum supported SQLite version has been increased from 3.27.0 to 3.40.0.

If you use current versions of the matrixorg/synapse Docker images, no action is required.

Deprecation of MacOS Python wheels

The team has decided to deprecate and eventually stop publishing python wheels for MacOS. This is a burden on the team, and we're not aware of any parties that use them. Synapse docker images will continue to work on MacOS, as will building Synapse from source (though note this requires a Rust compiler).

At present, publishing MacOS Python wheels will continue for the next release (1.143.0), but will not be available after that (1.144.0+). If you do make use of these wheels downstream, please reach out to us in #synapse-dev:matrix.org. We'd love to hear from you!

Bugfixes

• Fix a bug introduced in 1.142.0rc1 where any attempt to configure matrix_authentication_service.secret_path would prevent the homeserver from starting up. (#19144)
