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))
