+Synapse 1.44.0rc1 (2021-09-28)
+==============================
+
+Features
+--------
+
+- Only allow the [MSC2716](https://github.com/matrix-org/matrix-doc/pull/2716) `/batch_send?chunk_id=xxx` endpoint to connect to an already existing insertion event. ([\#10776](https://github.com/matrix-org/synapse/issues/10776))
+- Improve oEmbed previews by processing the author name, photo, and video information. ([\#10814](https://github.com/matrix-org/synapse/issues/10814), [\#10819](https://github.com/matrix-org/synapse/issues/10819))
+- Speed up responding with large JSON objects to requests. ([\#10868](https://github.com/matrix-org/synapse/issues/10868), [\#10905](https://github.com/matrix-org/synapse/issues/10905))
+- Add a `user_may_create_room_with_invites` spam checker callback to allow modules to allow or deny a room creation request based on the invites and/or 3PID invites it includes. ([\#10898](https://github.com/matrix-org/synapse/issues/10898))
+
+
+Bugfixes
+--------
+
+- Fix a long-standing bug that caused an `AssertionError` when purging history in certain rooms. Contributed by @Kokokokoka. ([\#10690](https://github.com/matrix-org/synapse/issues/10690))
+- Fix a long-standing bug which caused deactivated users that were later reactivated to be missing from the user directory. ([\#10782](https://github.com/matrix-org/synapse/issues/10782))
+- Allow sending a membership event to unban a user. Contributed by @aaronraimist. ([\#10807](https://github.com/matrix-org/synapse/issues/10807))
+- Fix a case where logging contexts would go missing when federation requests time out. ([\#10810](https://github.com/matrix-org/synapse/issues/10810))
+- Fix error in deprecated `/initialSync` endpoint when using the undocumented `from` and `to` parameters. ([\#10827](https://github.com/matrix-org/synapse/issues/10827))
+- Fix a bug causing the `remove_stale_pushers` background job to repeatedly fail and log errors. This bug affected Synapse servers that had been upgraded from version 1.28 or older and are using SQLite. ([\#10843](https://github.com/matrix-org/synapse/issues/10843))
+- Fix a bug in Unicode support of the room search admin API. It is now possible to search for rooms with non-ASCII characters. ([\#10859](https://github.com/matrix-org/synapse/issues/10859))
+- Fix a bug introduced in Synapse 1.37.0 which caused `knock` events which we sent to remote servers to be incorrectly stored in the local database. ([\#10873](https://github.com/matrix-org/synapse/issues/10873))
+- Fix invalidating one-time key count cache after claiming keys. Contributed by Tulir at Beeper. ([\#10875](https://github.com/matrix-org/synapse/issues/10875))
+- Fix application service users being subject to MAU blocking if MAU had been reached, even if configured not to be blocked. ([\#10881](https://github.com/matrix-org/synapse/issues/10881))
+- Allow the `.` and `~` characters when creating registration tokens as per the change to [MSC3231](https://github.com/matrix-org/matrix-doc/pull/3231). ([\#10887](https://github.com/matrix-org/synapse/issues/10887))
+- Fix a long-standing bug which could cause events pulled over federation to be incorrectly rejected. ([\#10907](https://github.com/matrix-org/synapse/issues/10907))
+- Avoid storing URL cache files in storage providers. Server admins may safely delete the `url_cache/` and `url_cache_thumbnails/` directories from any configured storage providers to reclaim space. ([\#10911](https://github.com/matrix-org/synapse/issues/10911))
+- Fix race conditions when creating media store and config directories. ([\#10913](https://github.com/matrix-org/synapse/issues/10913))
+- Fix debian builds due to dh-virtualenv no longer being able to build their docs. ([\#10931](https://github.com/matrix-org/synapse/issues/10931))
+
+
+Improved Documentation
+----------------------
+
+- Fix some crashes in the Module API example code, by adding JSON encoding/decoding. ([\#10845](https://github.com/matrix-org/synapse/issues/10845))
+- Add developer documentation about experimental configuration flags. ([\#10865](https://github.com/matrix-org/synapse/issues/10865))
+- Properly remove deleted files from GitHub pages when generating the documentation. ([\#10869](https://github.com/matrix-org/synapse/issues/10869))
+
+
+Internal Changes
+----------------
+
+- Fix GitHub Actions config so we can run sytest on synapse from parallel branches. ([\#10659](https://github.com/matrix-org/synapse/issues/10659))
+- Split out [MSC2716](https://github.com/matrix-org/matrix-doc/pull/2716) meta events to their own fields in the `/batch_send` response. ([\#10777](https://github.com/matrix-org/synapse/issues/10777))
+- Add missing type hints to REST servlets. ([\#10785](https://github.com/matrix-org/synapse/issues/10785), [\#10817](https://github.com/matrix-org/synapse/issues/10817))

+- Add type hints to the state database. ([\#10823](https://github.com/matrix-org/synapse/issues/10823))
+- Opt out of cache expiry for `get_users_who_share_room_with_user`, to hopefully improve `/sync` performance when you
+  haven't synced recently. ([\#10826](https://github.com/matrix-org/synapse/issues/10826))
