+Synapse 1.46.0 (2021-11-02)
+===========================
+
+The cause of the [performance regression affecting Synapse 1.44](https://github.com/matrix-org/synapse/issues/11049) has been identified and fixed. ([\#11177](https://github.com/matrix-org/synapse/issues/11177))
+
+Bugfixes
+--------
+
+- Fix a bug introduced in v1.46.0rc1 where URL previews of some XML documents would fail. ([\#11196](https://github.com/matrix-org/synapse/issues/11196))
+
+
+Synapse 1.46.0rc1 (2021-10-27)
+==============================
+
+Features
+--------
+
+- Add support for Ubuntu 21.10 "Impish Indri". ([\#11024](https://github.com/matrix-org/synapse/issues/11024))
+- Port the Password Auth Providers module interface to the new generic interface. ([\#10548](https://github.com/matrix-org/synapse/issues/10548), [\#11180](https://github.com/matrix-org/synapse/issues/11180))
+- Experimental support for the thread relation defined in [MSC3440](https://github.com/matrix-org/matrix-doc/pull/3440). ([\#11088](https://github.com/matrix-org/synapse/issues/11088), [\#11181](https://github.com/matrix-org/synapse/issues/11181), [\#11192](https://github.com/matrix-org/synapse/issues/11192))
+- Users admin API can now also modify user type in addition to allowing it to be set on user creation. ([\#11174](https://github.com/matrix-org/synapse/issues/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. ([\#10930](https://github.com/matrix-org/synapse/issues/10930))
+- Fix a long-standing bug which meant that events received over federation were sometimes incorrectly accepted into the room state. ([\#11001](https://github.com/matrix-org/synapse/issues/11001), [\#11009](https://github.com/matrix-org/synapse/issues/11009), [\#11012](https://github.com/matrix-org/synapse/issues/11012))
+- Fix 500 error on `/messages` when the server accumulates more than 5 backwards extremities at a given depth for a room. ([\#11027](https://github.com/matrix-org/synapse/issues/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. ([\#11051](https://github.com/matrix-org/synapse/issues/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. ([\#11075](https://github.com/matrix-org/synapse/issues/11075))
+- Fix a long-standing bug when attempting to preview URLs which are in the `windows-1252` character encoding. ([\#11077](https://github.com/matrix-org/synapse/issues/11077), [\#11089](https://github.com/matrix-org/synapse/issues/11089))
+- Fix broken export-data admin command and add test script checking the command to CI. ([\#11078](https://github.com/matrix-org/synapse/issues/11078))
+- Show an error when timestamp in seconds is provided to the `/purge_media_cache` Admin API. ([\#11101](https://github.com/matrix-org/synapse/issues/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. ([\#11103](https://github.com/matrix-org/synapse/issues/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. ([\#11112](https://github.com/matrix-org/synapse/issues/11112))
+- Identity server connection is no longer ignoring `ip_range_whitelist`. ([\#11120](https://github.com/matrix-org/synapse/issues/11120))
+- Fix a bug introduced in Synapse 1.45.0 breaking the configuration file parsing script. ([\#11145](https://github.com/matrix-org/synapse/issues/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. ([\#11177](https://github.com/matrix-org/synapse/issues/11177), [\#11190](https://github.com/matrix-org/synapse/issues/11190))
+- Resolve and share `state_groups` for all [MSC2716](https://github.com/matrix-org/matrix-doc/pull/2716) historical events in batch. ([\#10975](https://github.com/matrix-org/synapse/issues/10975))
+
+
+Improved Documentation
+----------------------
+
+- Fix broken links relating to module API deprecation in the upgrade notes. ([\#11069](https://github.com/matrix-org/synapse/issues/11069))
+- Add more information about what happens when a user is deactivated. ([\#11083](https://github.com/matrix-org/synapse/issues/11083))
+- Clarify the the sample log config can be copied from the documentation without issue. ([\#11092](https://github.com/matrix-org/synapse/issues/11092))
+- Update the admin API documentation with an updated list of the characters allowed in registration tokens. ([\#11093](https://github.com/matrix-org/synapse/issues/11093))
+- Document Synapse's behaviour when dealing with multiple modules registering the same callbacks and/or handlers for the same HTTP endpoints. ([\#11096](https://github.com/matrix-org/synapse/issues/11096))
+- Fix instances of `[example]{.title-ref}` in the upgrade documentation as a result of prior RST to Markdown conversion. ([\#11118](https://github.com/matrix-org/synapse/issues/11118))
+- Document the version of Synapse each module callback was introduced in. ([\#11132](https://github.com/matrix-org/synapse/issues/11132))
+- Document the version of Synapse that introduced each module API method. ([\#11183](https://github.com/matrix-org/synapse/issues/11183))
+
+

+- Include rejected status when we log events. ([\#11008](https://github.com/matrix-org/synapse/issues/11008))
+- Add some extra logging to the event persistence code. ([\#11014](https://github.com/matrix-org/synapse/issues/11014))
+- Rearrange the internal workings of the incremental user directory updates. ([\#11035](https://github.com/matrix-org/synapse/issues/11035))
+- Fix a long-standing bug where users excluded from the directory could still be added to the `users_who_share_private_rooms` table after a regular user joins a private room. ([\#11143](https://github.com/matrix-org/synapse/issues/11143))
+- Add and improve type hints. ([\#10972](https://github.com/matrix-org/synapse/issues/10972), [\#11055](https://github.com/matrix-org/synapse/issues/11055), [\#11066](https://github.com/matrix-org/synapse/issues/11066), [\#11076](https://github.com/matrix-org/synapse/issues/11076), [\#11095](https://github.com/matrix-org/synapse/issues/11095), [\#11109](https://github.com/matrix-org/synapse/issues/11109), [\#11121](https://github.com/matrix-org/synapse/issues/11121), [\#11146](https://github.com/matrix-org/synapse/issues/11146))
+- Mark the Synapse package as containing type annotations and fix export declarations so that Synapse pluggable modules may be type checked against Synapse. ([\#11054](https://github.com/matrix-org/synapse/issues/11054))
+- Remove dead code from `MediaFilePaths`. ([\#11056](https://github.com/matrix-org/synapse/issues/11056))
+- Be more lenient when parsing oEmbed response versions. ([\#11065](https://github.com/matrix-org/synapse/issues/11065))
+- Create a separate module for the retention configuration. ([\#11070](https://github.com/matrix-org/synapse/issues/11070))
+- Clean up some of the federation event authentication code for clarity. ([\#11115](https://github.com/matrix-org/synapse/issues/11115), [\#11116](https://github.com/matrix-org/synapse/issues/11116), [\#11122](https://github.com/matrix-org/synapse/issues/11122))
+- Add docstrings and comments to the application service ephemeral event sending code. ([\#11138](https://github.com/matrix-org/synapse/issues/11138))
