Synapse 1.65.0rc1 (2022-08-09)

Features

• Add support for stable prefixes for MSC2285 (private read receipts). (#13273)
• Add new unstable error codes ORG.MATRIX.MSC3848.ALREADY_JOINED, ORG.MATRIX.MSC3848.NOT_JOINED, and ORG.MATRIX.MSC3848.INSUFFICIENT_POWER described in MSC3848. (#13343)
• Use stable prefixes for MSC3827. (#13370)
• Add a new module API method to translate a room alias into a room ID. (#13428)
• Add a new module API method to create a room. (#13429)
• Add remote join capability to the module API's update_room_membership method (in a backwards compatible manner). (#13441)

Bugfixes

• Update the version of the LDAP3 auth provider module included in the matrixdotorg/synapse DockerHub images and the Debian packages hosted on packages.matrix.org to 0.2.2. This version fixes a regression in the module. (#13470)
• Fix a bug introduced in Synapse v1.41.0 where the /hierarchy API returned non-standard information (a room_id field under each entry in children_state). (#13365)
• Fix a bug introduced in Synapse 0.24.0 that would respond with the wrong error status code to /joined_members requests when the requester is not a current member of the room. Contributed by @andrewdoh. (#13374)
• Fix bug in handling of typing events for appservices. Contributed by Nick @ Beeper (@Fizzadar). (#13392)
• Fix a bug introduced in Synapse 1.57.0 where rooms listed in exclude_rooms_from_sync in the configuration file would not be properly excluded from incremental syncs. (#13408)
• Fix a bug in the experimental faster-room-joins support which could cause it to get stuck in an infinite loop. (#13353)
• Faster room joins: fix a bug which caused rejected events to become un-rejected during state syncing. (#13413)
• Faster room joins: fix error when running out of servers to sync partial state with, so that Synapse raises the intended error instead. (#13432)

Updates to the Docker image

• Make Docker images build on armv7 by installing cryptography dependencies in the 'requirements' stage. Contributed by Jasper Spaans. (#13372)

Improved Documentation

• Update the 'registration tokens' page to acknowledge that the relevant MSC was merged into version 1.2 of the Matrix specification. Contributed by @moan0s. (#11897)
• Document which HTTP resources support gzip compression. (#13221)
• Add steps describing how to elevate an existing user to administrator by manipulating the database. (#13230)
• Fix wrong headline for url_preview_accept_language in documentation. (#13437)
• Remove redundant 'Contents' section from the Configuration Manual. Contributed by @dklimpel. (#13438)
• Update documentation for config setting macaroon_secret_key. (#13443)
• Update outdated information on sso_mapping_providers documentation. (#13449)
• Fix example code in module documentation of password_auth_provider_callbacks. (#13450)
• Make the configuration for the cache clearer. (#13481)

Internal Changes

• Extend the release script to automatically push a new SyTest branch, rather than having that be a manual process. (#12978)
• Make minor clarifications to the error messages given when we fail to join a room via any server. (#13160)
• Enable Complement CI tests in the 'latest deps' test run. (#13213)
• Fix long-standing bugged logic which was never hit in get_pdu asking every remote destination even after it finds an event. (#13346)
• Faster room joins: avoid blocking when pulling events with partially missing prev events. (#13355)
• Instrument /messages for understandable traces in Jaeger. (#13368)
• Remove an unused argument to get_relations_for_event. (#13383)
• Add a merge-back command to the release script, which automates merging the correct branches after a release. (#13393)
• Adding missing type hints to tests. (#13397)
• Faster Room Joins: don't leave a stuck room partial state flag if the join fails. (#13403)
• Refactor _resolve_state_at_missing_prevs to compute an EventContext instead. (#13404, #13431)
• Faster Room Joins: prevent Synapse from answering federated join requests for a room which it has not fully joined yet. (#13416)
• Re-enable running Complement tests against Synapse with workers. (#13420)
• Prevent unnecessary lookups to any external get_event cache. Contributed by Nick @ Beeper (@Fizzadar). (#13435)
• Add some tracing to give more insight into local room joins. (#13439)
• Rename class RateLimitConfig to RatelimitSettings and FederationRateLimitConfig to FederationRatelimitSettings. (#13442)
• Add some comments about how event push actions are stored. (#13445, #13455)
• Improve rebuild speed for the "synapse-workers" docker image. (#13447)
• Fix @tag_args being off-by-one with the arguments when tagging a span (tracing). (#13452)
• Update type of EventContext.rejected. (#13460)
• Use literals in place of HTTPStatus constants in tests. (#13463, #13469)
• Correct a misnamed argument in state res v2 internals. (#13467)
