Synapse 1.10.0 (2020-02-12) =========================== **WARNING to client developers**: As of this release Synapse validates `client_secret` parameters in the Client-Server API as per the spec. See [\#6766](https://github.com/matrix-org/synapse/issues/6766) for details. Updates to the Docker image --------------------------- - Update the docker images to Alpine Linux 3.11. ([\#6897](https://github.com/matrix-org/synapse/issues/6897)) Synapse 1.10.0rc5 (2020-02-11) ============================== Bugfixes -------- - Fix the filtering introduced in 1.10.0rc3 to also apply to the state blocks returned by `/sync`. ([\#6884](https://github.com/matrix-org/synapse/issues/6884)) Synapse 1.10.0rc4 (2020-02-11) ============================== This release candidate was built incorrectly and is superceded by 1.10.0rc5. Synapse 1.10.0rc3 (2020-02-10) ============================== Features -------- - Filter out `m.room.aliases` from the CS API to mitigate abuse while a better solution is specced. ([\#6878](https://github.com/matrix-org/synapse/issues/6878)) Internal Changes ---------------- - Fix continuous integration failures with old versions of `pip`, which were introduced by a release of the `zipp` library. ([\#6880](https://github.com/matrix-org/synapse/issues/6880)) Synapse 1.10.0rc2 (2020-02-06) ============================== Bugfixes -------- - Fix an issue with cross-signing where device signatures were not sent to remote servers. ([\#6844](https://github.com/matrix-org/synapse/issues/6844)) - Fix to the unknown remote device detection which was introduced in 1.10.rc1. ([\#6848](https://github.com/matrix-org/synapse/issues/6848)) Internal Changes ---------------- - Detect unexpected sender keys on remote encrypted events and resync device lists. ([\#6850](https://github.com/matrix-org/synapse/issues/6850)) Synapse 1.10.0rc1 (2020-01-31) ============================== Features -------- - Add experimental support for updated authorization rules for aliases events, from [MSC2260](https://github.com/matrix-org/matrix-doc/pull/2260). ([\#6787](https://github.com/matrix-org/synapse/issues/6787), [\#6790](https://github.com/matrix-org/synapse/issues/6790), [\#6794](https://github.com/matrix-org/synapse/issues/6794)) Bugfixes -------- - Warn if postgres database has a non-C locale, as that can cause issues when upgrading locales (e.g. due to upgrading OS). ([\#6734](https://github.com/matrix-org/synapse/issues/6734)) - Minor fixes to `PUT /_synapse/admin/v2/users` admin api. ([\#6761](https://github.com/matrix-org/synapse/issues/6761)) - Validate `client_secret` parameter using the regex provided by the Client-Server API, temporarily allowing `:` characters for older clients. The `:` character will be removed in a future release. ([\#6767](https://github.com/matrix-org/synapse/issues/6767)) - Fix persisting redaction events that have been redacted (or otherwise don't have a redacts key). ([\#6771](https://github.com/matrix-org/synapse/issues/6771)) - Fix outbound federation request metrics. ([\#6795](https://github.com/matrix-org/synapse/issues/6795)) - Fix bug where querying a remote user's device keys that weren't cached resulted in only returning a single device. ([\#6796](https://github.com/matrix-org/synapse/issues/6796)) - Fix race in federation sender worker that delayed sending of device updates. ([\#6799](https://github.com/matrix-org/synapse/issues/6799), [\#6800](https://github.com/matrix-org/synapse/issues/6800)) - Fix bug where Synapse didn't invalidate cache of remote users' devices when Synapse left a room. ([\#6801](https://github.com/matrix-org/synapse/issues/6801)) - Fix waking up other workers when remote server is detected to have come back online. ([\#6811](https://github.com/matrix-org/synapse/issues/6811)) Improved Documentation ---------------------- - Clarify documentation related to `user_dir` and `federation_reader` workers. ([\#6775](https://github.com/matrix-org/synapse/issues/6775)) Internal Changes ---------------- - Record room versions in the `rooms` table. ([\#6729](https://github.com/matrix-org/synapse/issues/6729), [\#6788](https://github.com/matrix-org/synapse/issues/6788), [\#6810](https://github.com/matrix-org/synapse/issues/6810)) - Propagate cache invalidates from workers to other workers. ([\#6748](https://github.com/matrix-org/synapse/issues/6748)) - Remove some unnecessary admin handler abstraction methods. ([\#6751](https://github.com/matrix-org/synapse/issues/6751)) - Add some debugging for media storage providers. ([\#6757](https://github.com/matrix-org/synapse/issues/6757)) - Detect unknown remote devices and mark cache as stale. ([\#6776](https://github.com/matrix-org/synapse/issues/6776), [\#6819](https://github.com/matrix-org/synapse/issues/6819)) - Attempt to resync remote users' devices when detected as stale. ([\#6786](https://github.com/matrix-org/synapse/issues/6786)) - Delete current state from the database when server leaves a room. ([\#6792](https://github.com/matrix-org/synapse/issues/6792)) - When a client asks for a remote user's device keys check if the local cache for that user has been marked as potentially stale. ([\#6797](https://github.com/matrix-org/synapse/issues/6797)) - Add background update to clean out left rooms from current state. ([\#6802](https://github.com/matrix-org/synapse/issues/6802), [\#6816](https://github.com/matrix-org/synapse/issues/6816)) - Refactoring work in preparation for changing the event redaction algorithm. ([\#6803](https://github.com/matrix-org/synapse/issues/6803), [\#6805](https://github.com/matrix-org/synapse/issues/6805), [\#6806](https://github.com/matrix-org/synapse/issues/6806), [\#6807](https://github.com/matrix-org/synapse/issues/6807), [\#6820](https://github.com/matrix-org/synapse/issues/6820))
