Subject: [PATCH 07/37] Fix `Current state appears in timeline in private
 history with many messages after` (#2830)

The problem was that we weren't getting enough recent events, as most of
them were removed by the history visibility filter. Now we're getting
all events between the given input range and re-slice the returned
values after applying history visibility.

Subject: [PATCH 14/37] Add scheduled tasks to run tests with race detection
 (#2814)

Needs https://github.com/matrix-org/sytest/pull/1308 to be actually
useful.
Not sure if we need to run Sytest in all combinations with enabled race
detection.

Closes https://github.com/matrix-org/dendrite/issues/491

`DELTE
/_matrix/client/v3/directory/list/appservice/{networkId}/{roomId}`
support, as well as the ability to filter `/publicRooms` on networkID
and including all networks.

Subject: [PATCH 20/37] Add hcaptcha support besides Google ReCaptcha (#2834)

### Pull Request Checklist
This PR add support for hcaptcha.com as an alternative to Google
ReCaptcha. It also makes possible for user to customize ReCaptcha URL
when needed. (Such as use recaptcha.net instead of www.google.com)

This feature needs manual test cuz it involves 3rd party _captcha_.

If we're going backwards, we were selecting potentially thousands of

Subject: [PATCH 24/37] Tweak `"state"` and `"timeline"` filtering (#2844)

This should stop state events disappearing down a gap where we'd try to
separate out the sections *before* applying history visibility instead
of after.

This may be a better approach than #2843 but I hope @tak-hntlabs will
shout if it isn't.

 # Changelog
 
+## Dendrite 0.10.5 (2022-10-31)
+
+### Features
+
+* It is now possible to use hCaptcha instead of reCAPTCHA for protecting registration
+* A new `auto_join_rooms` configuration option has been added for automatically joining new users to a set of rooms
+* A new `/_dendrite/admin/downloadState/{serverName}/{roomID}` endpoint has been added, which allows a server administrator to attempt to repair a room with broken room state by downloading a state snapshot from another federated server in the room
+
+### Fixes
+
+* Querying cross-signing keys for users should now be considerably faster
+* A bug in state resolution where some events were not correctly selected for third-party invites has been fixed
+* A bug in state resolution which could result in `not in room` event rejections has been fixed
+* When accepting a DM invite, it should now be possible to see messages that were sent before the invite was accepted
+* Claiming remote E2EE one-time keys has been refactored and should be more reliable now
+* Various fixes have been made to the `/members` endpoint, which may help with E2EE reliability and clients rendering memberships
+* A race condition in the federation API destination queues has been fixed when associating queued events with remote server destinations
+* A bug in the sync API where too many events were selected resulting in high CPU usage has been fixed
+* Configuring the avatar URL for the Server Notices user should work correctly now
+
 ## Dendrite 0.10.4 (2022-10-21)

 # Changelog
 
+## Dendrite 0.10.6 (2022-11-01)
+
+### Features
+
+* History visibility checks have been optimised, which should speed up response times on a variety of endpoints (including `/sync`, `/messages`, `/context` and others) and reduce database load
+* The built-in NATS Server has been updated to version 2.9.4
+* Some other minor dependencies have been updated
+
+### Fixes
+
+* A panic has been fixed in the sync API PDU stream which could cause requests to fail
+* The `/members` response now contains the `room_id` field, which may fix some E2EE problems with clients using the JS SDK (contributed by [ashkitten](https://github.com/ashkitten))
+* The auth difference calculation in state resolution v2 has been tweaked for clarity (and moved into gomatrixserverlib with the rest of the state resolution code)
+
 ## Dendrite 0.10.5 (2022-10-31)
