Synapse 1.73.0rc1 (2022-11-29)

NB: This release was found to have a major performance regression. We have not published Debian packages to packages.matrix.org, not wheels to PyPI for this release; see version 1.73.0rc2 instead.

Please note that legacy Prometheus metric names have been removed in this release; see the upgrade notes for more details.

Features

• Speed-up /messages with filter_events_for_client optimizations. (#14527)
• Improve DB performance by reducing amount of data that gets read in device_lists_changes_in_room. (#14534)
• Adds support for handling avatar in SSO login. Contributed by @ashfame. (#13917)
• Move MSC3030 /timestamp_to_event endpoints to stable v1 location (/_matrix/client/v1/rooms/<roomID>/timestamp_to_event?ts=<timestamp>&dir=<direction>, /_matrix/federation/v1/timestamp_to_event/<roomID>?ts=<timestamp>&dir=<direction>). (#14471)
• Reduce database load of Client-Server endpoints which return bundled aggregations. (#14491, #14508, #14510)
• Add unstable support for an Extensible Events room version (org.matrix.msc1767.10) via MSC1767, MSC3931, MSC3932, and MSC3933. (#14520, #14521, #14524)
• Prune user's old devices on login if they have too many. (#14038, #14580)

Bugfixes

• Fix a long-standing bug where paginating from the start of a room did not work. Contributed by @gnunicorn. (#14149)
• Fix a bug introduced in Synapse 1.58.0 where a user with presence state org.matrix.msc3026.busy would mistakenly be set to online when calling /sync or /events on a worker process. (#14393)
• Fix a bug introduced in Synapse 1.70.0 where a receipt's thread ID was not sent over federation. (#14466)
• Fix a long-standing bug where the List media admin API would fail when processing an image with broken thumbnail information. (#14537)
• Fix a bug introduced in Synapse 1.67.0 where two logging context warnings would be logged on startup. (#14574)
• In application service transactions that include the experimental org.matrix.msc3202.device_one_time_key_counts key, include a duplicate key of org.matrix.msc3202.device_one_time_keys_count to match the name proposed by MSC3202. (#14565)
• Fix a bug introduced in Synapse 0.9 where Synapse would fail to fetch server keys whose IDs contain a forward slash. (#14490)

Improved Documentation

• Fixed link to 'Synapse administration endpoints'. (#14499)

Deprecations and Removals

• Remove legacy Prometheus metrics names. They were deprecated in Synapse v1.69.0 and disabled by default in Synapse v1.71.0. (#14538)

Internal Changes

• Improve type hinting throughout Synapse. (#14055, #14412, #14529, #14452).
• Remove old stream ID tracking code. Contributed by Nick @beeper (@Fizzadar). (#14376, #14468)
• Remove the worker_main_http_uri configuration setting. This is now handled via internal replication. (#14400, #14476)
• Refactor federation_sender and pusher configuration loading. (#14496)
  (#14509, #14573)
• Faster joins: do not wait for full state when creating events to send. (#14403)
• Faster joins: filter out non local events when a room doesn't have its full state. (#14404)
• Faster joins: send events to initial list of servers if we don't have the full state yet. (#14408)
• Faster joins: use servers list approximation received during send_join (potentially updated with received membership events) in assert_host_in_room. (#14515)
• Fix type logic in TCP replication code that prevented correctly ignoring blank commands. (#14449)
• Remove option to skip locking of tables when performing emulated upserts, to avoid a class of bugs in future. (#14469)
• scripts-dev/federation_client: Fix routing on servers with .well-known files. (#14479)
• Reduce default third party invite rate limit to 216 invites per day. (#14487)
• Refactor conversion of device list changes in room to outbound pokes to track unconverted rows using a (stream ID, room ID) position instead of updating the converted_to_destinations flag on every row. (#14516)
• Add more prompts to the bug report form. (#14522)
• Extend editorconfig rules on indent and line length to .pyi files. (#14526)
• Run Rust CI when Cargo.lock changes. This is particularly useful for dependabot updates. (#14571)
• Fix a possible variable shadow in create_new_client_event. (#14575)
• Bump various dependencies in the poetry.lock file and in CI scripts. (#14557, #14559, #14560, #14500, #14501, #14502, #14503, #14504, #14505).
