+Synapse 1.46.0rc1 (2021-10-26)
+==============================
+
+Features
+--------
+
+- 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))
+- 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))
+- 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))
+- 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 users 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 v1.45.0 breaking the configuration file parsing script. ([\#11145](https://github.com/matrix-org/synapse/issues/11145))
+- Fix a performance regression introduced in v1.44.0 which could cause client requests to time out when making large numbers of outbound requests. ([\#11177](https://github.com/matrix-org/synapse/issues/11177))
+
+

+
+- 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))
