In state res v2, we apply two passes of iterative auth checks. The first pass replays power events and events in their auth chains, but only those belonging to the full conflicted set. The source code as written suggests that we want only those belonging to the auth difference (which is a smaller set of events). At runtime we were doing the correct thing anyway, because the only callsite of `_reverse_topological_power_sort` passes in the `full_conflicted_set`. So this really is just a rename.

Synapse 1.65.0 (2022-08-16) =========================== No significant changes since 1.65.0rc2. Synapse 1.65.0rc2 (2022-08-11) ============================== Internal Changes ---------------- - Revert 'Remove the unspecced `room_id` field in the `/hierarchy` response. ([\matrix-org#13365](matrix-org#13365))' to give more time for clients to update. ([\matrix-org#13501](matrix-org#13501)) Synapse 1.65.0rc1 (2022-08-09) ============================== Features -------- - Add support for stable prefixes for [MSC2285 (private read receipts)](matrix-org/matrix-spec-proposals#2285). ([\matrix-org#13273](matrix-org#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](matrix-org/matrix-spec-proposals#3848). ([\matrix-org#13343](matrix-org#13343)) - Use stable prefixes for [MSC3827](matrix-org/matrix-spec-proposals#3827). ([\matrix-org#13370](matrix-org#13370)) - Add a new module API method to translate a room alias into a room ID. ([\matrix-org#13428](matrix-org#13428)) - Add a new module API method to create a room. ([\matrix-org#13429](matrix-org#13429)) - Add remote join capability to the module API's `update_room_membership` method (in a backwards compatible manner). ([\matrix-org#13441](matrix-org#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. ([\matrix-org#13470](matrix-org#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`). ([\matrix-org#13365](matrix-org#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. ([\matrix-org#13374](matrix-org#13374)) - Fix bug in handling of typing events for appservices. Contributed by Nick @ Beeper (@Fizzadar). ([\matrix-org#13392](matrix-org#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. ([\matrix-org#13408](matrix-org#13408)) - Fix a bug in the experimental faster-room-joins support which could cause it to get stuck in an infinite loop. ([\matrix-org#13353](matrix-org#13353)) - Faster room joins: fix a bug which caused rejected events to become un-rejected during state syncing. ([\matrix-org#13413](matrix-org#13413)) - Faster room joins: fix error when running out of servers to sync partial state with, so that Synapse raises the intended error instead. ([\matrix-org#13432](matrix-org#13432)) Updates to the Docker image --------------------------- - Make Docker images build on armv7 by installing cryptography dependencies in the 'requirements' stage. Contributed by Jasper Spaans. ([\matrix-org#13372](matrix-org#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. ([\matrix-org#11897](matrix-org#11897)) - Document which HTTP resources support gzip compression. ([\matrix-org#13221](matrix-org#13221)) - Add steps describing how to elevate an existing user to administrator by manipulating the database. ([\matrix-org#13230](matrix-org#13230)) - Fix wrong headline for `url_preview_accept_language` in documentation. ([\matrix-org#13437](matrix-org#13437)) - Remove redundant 'Contents' section from the Configuration Manual. Contributed by @dklimpel. ([\matrix-org#13438](matrix-org#13438)) - Update documentation for config setting `macaroon_secret_key`. ([\matrix-org#13443](matrix-org#13443)) - Update outdated information on `sso_mapping_providers` documentation. ([\matrix-org#13449](matrix-org#13449)) - Fix example code in module documentation of `password_auth_provider_callbacks`. ([\matrix-org#13450](matrix-org#13450)) - Make the configuration for the cache clearer. ([\matrix-org#13481](matrix-org#13481)) Internal Changes ---------------- - Extend the release script to automatically push a new SyTest branch, rather than having that be a manual process. ([\matrix-org#12978](matrix-org#12978)) - Make minor clarifications to the error messages given when we fail to join a room via any server. ([\matrix-org#13160](matrix-org#13160)) - Enable Complement CI tests in the 'latest deps' test run. ([\matrix-org#13213](matrix-org#13213)) - Fix long-standing bugged logic which was never hit in `get_pdu` asking every remote destination even after it finds an event. ([\matrix-org#13346](matrix-org#13346)) - Faster room joins: avoid blocking when pulling events with partially missing prev events. ([\matrix-org#13355](matrix-org#13355)) - Instrument `/messages` for understandable traces in Jaeger. ([\matrix-org#13368](matrix-org#13368)) - Remove an unused argument to `get_relations_for_event`. ([\matrix-org#13383](matrix-org#13383)) - Add a `merge-back` command to the release script, which automates merging the correct branches after a release. ([\matrix-org#13393](matrix-org#13393)) - Adding missing type hints to tests. ([\matrix-org#13397](matrix-org#13397)) - Faster Room Joins: don't leave a stuck room partial state flag if the join fails. ([\matrix-org#13403](matrix-org#13403)) - Refactor `_resolve_state_at_missing_prevs` to compute an `EventContext` instead. ([\matrix-org#13404](matrix-org#13404), [\matrix-org#13431](matrix-org#13431)) - Faster Room Joins: prevent Synapse from answering federated join requests for a room which it has not fully joined yet. ([\matrix-org#13416](matrix-org#13416)) - Re-enable running Complement tests against Synapse with workers. ([\matrix-org#13420](matrix-org#13420)) - Prevent unnecessary lookups to any external `get_event` cache. Contributed by Nick @ Beeper (@Fizzadar). ([\matrix-org#13435](matrix-org#13435)) - Add some tracing to give more insight into local room joins. ([\matrix-org#13439](matrix-org#13439)) - Rename class `RateLimitConfig` to `RatelimitSettings` and `FederationRateLimitConfig` to `FederationRatelimitSettings`.
