Synapse 1.116.0rc1 (2024-09-25)

Features

• Add initial implementation of delayed events as proposed by MSC4140. (#17326)
• Add an asynchronous Admin API endpoint to redact all a user's events,
  and an endpoint to check on the status of that redaction task. (#17506)
• Add support for the tags and not_tags filters for MSC4186 Sliding Sync. (#17662)
• Guests can use the new media endpoints to download media, as described by MSC4189. (#17675)
• Add config option turn_shared_secret_path. (#17690)
• Return room tags in MSC4186 Sliding Sync account data extension. (#17707)

Bugfixes

• Make sure we get up-to-date state information when using the new MSC4186 Sliding Sync tables to derive room membership. (#17692)
• Fix bug where room account data would not correctly be sent down MSC4186 Sliding Sync for old rooms. (#17695)
• Fix a bug in MSC4186 Sliding Sync which could prevent /sync from working for certain user accounts. (#17727, #17733)
• Ignore invites from ignored users in Sliding Sync. (#17729)
• Fix bug in MSC4186 Sliding Sync where the server would incorrectly return a negative bump stamp, which caused Element X apps to stop syncing. (#17748)

Internal Changes

• Import pydantic objects from the _pydantic_compat module.
  This allows check_pydantic_models.py to mock those pydantic objects
  only in the synapse module, and not interfere with pydantic objects in
  external dependencies. (#17667)
• Use MSC4186 Sliding Sync tables as a bulk shortcut for getting the max event_stream_ordering of rooms. (#17693)
• Speed up MSC4186 sliding sync requests a bit where there are many room changes. (#17696)
• Refactor MSC4186 sliding sync filter unit tests so the sliding sync API has better test coverage. (#17703)
• Fetch bump_stamps more efficiently in MSC4186 Sliding Sync. (#17723)
• Shortcut for checking if certain background updates have completed (utilized in MSC4186 Sliding Sync). (#17724)
• More efficiently fetch rooms for MSC4186 Sliding Sync. (#17725)
• Fix _bulk_get_max_event_pos being inefficient. (#17728)
• Add cache to get_tags_for_room(...). (#17730)
• Small performance improvement in speeding up MSC4186 Sliding Sync. (#17731)
• Minor speed up of initial MSC4186 sliding sync requests. (#17734)
• Remove usage of the deprecated cgi module, deprecated in Python 3.11 and removed in Python 3.13. (#17741)
• Fix typing of a variable that is not Unknown anymore after updating treq. (#17744)
