Synapse 1.0.0rc1 (2019-06-07) ============================= Features -------- - Synapse now more efficiently collates room statistics. ([\#4338](#4338), [\#5260](#5260), [\#5324](#5324)) - Add experimental support for relations (aka reactions and edits). ([\#5220](#5220)) - Ability to configure default room version. ([\#5223](#5223), [\#5249](#5249)) - Allow configuring a range for the account validity startup job. ([\#5276](#5276)) - CAS login will now hit the r0 API, not the deprecated v1 one. ([\#5286](#5286)) - Validate federation server TLS certificates by default (implements [MSC1711](https://github.com/matrix-org/matrix-doc/blob/master/proposals/1711-x509-for-federation.md)). ([\#5359](#5359)) - Update /_matrix/client/versions to reference support for r0.5.0. ([\#5360](#5360)) - Add a script to generate new signing-key files. ([\#5361](#5361)) - Update upgrade and installation guides ahead of 1.0. ([\#5371](#5371)) - Replace the `perspectives` configuration section with `trusted_key_servers`, and make validating the signatures on responses optional (since TLS will do this job for us). ([\#5374](#5374)) - Add ability to perform password reset via email without trusting the identity server. ([\#5377](#5377)) - Set default room version to v4. ([\#5379](#5379)) Bugfixes -------- - Fixes client-server API not sending "m.heroes" to lazy-load /sync requests when a rooms name or its canonical alias are empty. Thanks to @dnaf for this work! ([\#5089](#5089)) - Prevent federation device list updates breaking when processing multiple updates at once. ([\#5156](#5156)) - Fix worker registration bug caused by ClientReaderSlavedStore being unable to see get_profileinfo. ([\#5200](#5200)) - Fix race when backfilling in rooms with worker mode. ([\#5221](#5221)) - Fix appservice timestamp massaging. ([\#5233](#5233)) - Ensure that server_keys fetched via a notary server are correctly signed. ([\#5251](#5251)) - Show the correct error when logging out and access token is missing. ([\#5256](#5256)) - Fix error code when there is an invalid parameter on /_matrix/client/r0/publicRooms ([\#5257](#5257)) - Fix error when downloading thumbnail with missing width/height parameter. ([\#5258](#5258)) - Fix schema update for account validity. ([\#5268](#5268)) - Fix bug where we leaked extremities when we soft failed events, leading to performance degradation. ([\#5274](#5274), [\#5278](#5278), [\#5291](#5291)) - Fix "db txn 'update_presence' from sentinel context" log messages. ([\#5275](#5275)) - Fix dropped logcontexts during high outbound traffic. ([\#5277](#5277)) - Fix a bug where it is not possible to get events in the federation format with the request `GET /_matrix/client/r0/rooms/{roomId}/messages`. ([\#5293](#5293)) - Fix performance problems with the rooms stats background update. ([\#5294](#5294)) - Fix noisy 'no key for server' logs. ([\#5300](#5300)) - Fix bug where a notary server would sometimes forget old keys. ([\#5307](#5307)) - Prevent users from setting huge displaynames and avatar URLs. ([\#5309](#5309)) - Fix handling of failures when processing incoming events where calling `/event_auth` on remote server fails. ([\#5317](#5317)) - Ensure that we have an up-to-date copy of the signing key when validating incoming federation requests. ([\#5321](#5321)) - Fix various problems which made the signing-key notary server time out for some requests. ([\#5333](#5333)) - Fix bug which would make certain operations (such as room joins) block for 20 minutes while attemoting to fetch verification keys. ([\#5334](#5334)) - Fix a bug where we could rapidly mark a server as unreachable even though it was only down for a few minutes. ([\#5335](#5335), [\#5340](#5340)) - Fix a bug where account validity renewal emails could only be sent when email notifs were enabled. ([\#5341](#5341)) - Fix failure when fetching batches of events during backfill, etc. ([\#5342](#5342)) - Add a new room version where the timestamps on events are checked against the validity periods on signing keys. ([\#5348](#5348), [\#5354](#5354)) - Fix room stats and presence background updates to correctly handle missing events. ([\#5352](#5352)) - Include left members in room summaries' heroes.

`StatsHandler` handles updates to the `current_state_delta_stream`, and updates room stats such as the amount of state events, joined users, etc. However, it counts every new join membership as a new user entering a room (and that user being in another room), whereas it's possible for a user's membership status to go from join -> join, for instance when they change their per-room profile information. This PR adds a check for join->join membership transitions, and bails out early, as none of the further checks are necessary at that point. Due to this bug, membership stats in many rooms have ended up being wildly larger than their true values. I am not sure if we also want to include a migration step which recalculates these statistics (possibly using the `_populate_stats_process_rooms` bg update). Bug introduced in the initial implementation #4338.
