Synapse 1.46.0 (2021-11-02)
===========================

The cause of the [performance regression affecting Synapse 1.44](matrix-org#11049) has been identified and fixed. ([\matrix-org#11177](matrix-org#11177))

Bugfixes
--------

- Fix a bug introduced in v1.46.0rc1 where URL previews of some XML documents would fail. ([\matrix-org#11196](matrix-org#11196))

Synapse 1.46.0rc1 (2021-10-27)
==============================

Features
--------

- Add support for Ubuntu 21.10 "Impish Indri". ([\matrix-org#11024](matrix-org#11024))
- Port the Password Auth Providers module interface to the new generic interface. ([\matrix-org#10548](matrix-org#10548), [\matrix-org#11180](matrix-org#11180))
- Experimental support for the thread relation defined in [MSC3440](matrix-org/matrix-spec-proposals#3440). ([\matrix-org#11088](matrix-org#11088), [\matrix-org#11181](matrix-org#11181), [\matrix-org#11192](matrix-org#11192))
- Users admin API can now also modify user type in addition to allowing it to be set on user creation. ([\matrix-org#11174](matrix-org#11174))

Bugfixes
--------

- Newly-created public rooms are now only assigned an alias if the room's creation has not been blocked by permission settings. Contributed by @AndrewFerr. ([\matrix-org#10930](matrix-org#10930))
- Fix a long-standing bug which meant that events received over federation were sometimes incorrectly accepted into the room state. ([\matrix-org#11001](matrix-org#11001), [\matrix-org#11009](matrix-org#11009), [\matrix-org#11012](matrix-org#11012))
- Fix 500 error on `/messages` when the server accumulates more than 5 backwards extremities at a given depth for a room. ([\matrix-org#11027](matrix-org#11027))
- Fix a bug where setting a user's `external_id` via the admin API returns 500 and deletes user's existing external mappings if that external ID is already mapped. ([\matrix-org#11051](matrix-org#11051))
- Fix a long-standing bug where users excluded from the user directory were added into the directory if they belonged to a room which became public or private. ([\matrix-org#11075](matrix-org#11075))
- Fix a long-standing bug when attempting to preview URLs which are in the `windows-1252` character encoding. ([\matrix-org#11077](matrix-org#11077), [\matrix-org#11089](matrix-org#11089))
- Fix broken export-data admin command and add test script checking the command to CI. ([\matrix-org#11078](matrix-org#11078))
- Show an error when timestamp in seconds is provided to the `/purge_media_cache` Admin API. ([\matrix-org#11101](matrix-org#11101))
- Fix local users who left all their rooms being removed from the user directory, even if the `search_all_users` config option was enabled. ([\matrix-org#11103](matrix-org#11103))
- Fix a bug which caused the module API's `get_user_ip_and_agents` function to always fail on workers. `get_user_ip_and_agents` was introduced in 1.44.0 and did not function correctly on worker processes at the time. ([\matrix-org#11112](matrix-org#11112))
- Identity server connection is no longer ignoring `ip_range_whitelist`. ([\matrix-org#11120](matrix-org#11120))
- Fix a bug introduced in Synapse 1.45.0 breaking the configuration file parsing script. ([\matrix-org#11145](matrix-org#11145))
- Fix a performance regression introduced in 1.44.0 which could cause client requests to time out when making large numbers of outbound requests. ([\matrix-org#11177](matrix-org#11177), [\matrix-org#11190](matrix-org#11190))
- Resolve and share `state_groups` for all [MSC2716](matrix-org/matrix-spec-proposals#2716) historical events in batch. ([\matrix-org#10975](matrix-org#10975))

Improved Documentation
----------------------

- Fix broken links relating to module API deprecation in the upgrade notes. ([\matrix-org#11069](matrix-org#11069))
- Add more information about what happens when a user is deactivated. ([\matrix-org#11083](matrix-org#11083))
- Clarify the the sample log config can be copied from the documentation without issue. ([\matrix-org#11092](matrix-org#11092))
- Update the admin API documentation with an updated list of the characters allowed in registration tokens. ([\matrix-org#11093](matrix-org#11093))
- Document Synapse's behaviour when dealing with multiple modules registering the same callbacks and/or handlers for the same HTTP endpoints. ([\matrix-org#11096](matrix-org#11096))
- Fix instances of `[example]{.title-ref}` in the upgrade documentation as a result of prior RST to Markdown conversion. ([\matrix-org#11118](matrix-org#11118))
- Document the version of Synapse each module callback was introduced in. ([\matrix-org#11132](matrix-org#11132))
- Document the version of Synapse that introduced each module API method. ([\matrix-org#11183](matrix-org#11183))

- Add and improve type hints. ([\matrix-org#10972](matrix-org#10972), [\matrix-org#11055](matrix-org#11055), [\matrix-org#11066](matrix-org#11066), [\matrix-org#11076](matrix-org#11076), [\matrix-org#11095](matrix-org#11095), [\matrix-org#11109](matrix-org#11109), [\matrix-org#11121](matrix-org#11121), [\matrix-org#11146](matrix-org#11146))
- Mark the Synapse package as containing type annotations and fix export declarations so that Synapse pluggable modules may be type checked against Synapse. ([\matrix-org#11054](matrix-org#11054))
- Remove dead code from `MediaFilePaths`. ([\matrix-org#11056](matrix-org#11056))
