Synapse 1.48.0 is out now!
NOTE: Synapse 1.49, due out on December 14th, will be the last release of Synapse to support Python 3.6 or PostgreSQL 9.6 per our platform dependency deprecation policy. Accordingly, we will remove support for Ubuntu 18.04 LTS (Bionic) at the same date, as it ships with Python 3.6.
Password resets and identity servers
This release removes the long-deprecated
trust_identity_server_for_password_resets configuration option. This option was initially deprecated in Synapse 1.4.0 back in October 2019.
Admins of servers still using this configuration option will need to update their Synapse configuration to send password resets through an SMTP server directly rather than relying on identity servers to send them on their behalf.
New admin APIs and improved alignment with Matrix 1.1
This release also introduces a handful of new admin APIs, allowing administrators to un-shadow-ban users, block a room, and run specific background updates (but we'll talk about this last one a bit later on). The delete room API has also been updated to be able to run in the background or to block a room pre-emptively, even if the server doesn't know about it yet.
This release also brings Synapse into greater alignment with version 1.1 of the Matrix specification by adding support for API paths beginning
When Synapse updates from one version to another, it might need to run large scale updates on its database. In order to avoid blocking startup for too long while waiting for these updates to run, Synapse runs them in the background after starting.
Lately the Synapse team has been doing some work to improve the performance of these background updates. More specifically, this release includes a performance fix for a background update introduced in Synapse 1.47.0, as well as a new admin API to let admins rerun specific updates.
This release also includes some improved support of MSC3440 to help threading. It also adds support for the stable identifiers from MSC2778, bringing Synapse closer to supporting end-to-end (or end-to-bridge) encryption support for application services.
We also now publish a Docker image,
matrixdotorg/synapse:develop, which tracks the development head of Synapse.
