Synapse 1.32.0 (2021-04-20)

WARNING: We've identified a load issue with Prometheus metrics in this release; we encourage you to wait for 1.32.1 which should be published tomorrow (April 21st).

Note: This release requires Python 3.6+ and Postgres 9.6+ or SQLite 3.22+.

This release removes the deprecated GET /_synapse/admin/v1/users/<user_id> admin API. Please use the v2 API instead, which has improved capabilities.

This release requires Application Services to use type m.login.application_service when registering users via the /_matrix/client/r0/register endpoint to comply with the spec. Please ensure your Application Services are up to date.

If you are using the packages.matrix.org Debian repository for Synapse packages, note that we have recently updated the expiry date on the gpg signing key. If you see an error similar to The following signatures were invalid: EXPKEYSIG F473DD4473365DE1, you will need to get a fresh copy of the keys. You can do so with:

sudo wget -O /usr/share/keyrings/matrix-org-archive-keyring.gpg https://packages.matrix.org/debian/matrix-org-archive-keyring.gpg
