Hey all, Synapse 1.62 is out! Let's have a look inside.
Spam checker improvements
In the past few weeks, the Synapse team has been working with the Matrix.org Trust & Safety team to help module developers build more efficient protections against spam. As a consequence of this work, Synapse 1.62 introduces new ways for modules to communicate the result of actions taken against a specific message or operation through the spam checker module callbacks.
Previously, most spam checker callbacks would be expected to return a boolean
indicating whether a specific operation should be qualified as spam. Starting
from Synapse 1.62, modules are now expected to return either
synapse.module_api.NOT_SPAM (to indicate an action is not spammy), or an error
code that is part of
Note that the previous behaviour is still supported but is now deprecated, and will be removed in a future version of Synapse.
See the upgrade
for a list of the affected callbacks and an example of this change. Note that on
top of the list described there, the
check_event_for_spam callback was also
updated with a similar
in Synapse 1.61.
This release of Synapse includes important performance improvements around syncing, specifically around handling device lists and notifications.
Synapse is a Free and Open Source Software project, and we'd like to extend our thanks to everyone who contributed to this release, including (in no particular order) Beeper, Sami Olmari, Daniel Aloni, Thumbscrew and Hannes Lerchl.
