 # Changelog
 
+## Dendrite 0.13.7 (2024-04-09)
+
+### Fixes
+
+- Fixed an issue where the displayname/avatar of an invited user was replaced with the inviter's details
+- Improved server startup performance by avoiding unnecessary room ACL queries
+  - This change reduces memory footprint as it caches ACL regex patterns once instead of for each room
+  - Unnecessary Relay related queries have been removed. **Note**: To use relays, you now need to explicitly enable them using the `federation_api.enable_relays` config
+- Fixed space summaries over federation
+- Improved usage of external NATS JetStream by reusing existing connections instead of opening new ones unnecessarily
+
+### Features
+
+- Modernized Appservices (contributed by [tulir](https://github.com/tulir))
+- Added event reporting with Synapse Admin endpoints for querying them
+- Updated dependencies
+
+## Dendrite 0.13.6 (2024-01-26)
+
+Upgrading to this version is **highly** recommended, as it contains several QoL improvements.
+
+### Fixes
+
+- Use `AckExplicitPolicy` for JetStream consumers, so messages don't pile up in NATS
+- A rare panic when assigning a state key NID has been fixed
+- A rare panic when checking powerlevels has been fixed
+- Notary keys requests for all keys now work correctly
+- Spec compliance:
+  - Return `M_INVALID_PARAM` when querying room aliases
+  - Handle empty `from` parameter when requesting `/messages`
+  - Add CORP headers on media endpoints
+  - Remove `aliases` from `/publicRooms` responses
+  - Allow `+` in MXIDs (Contributed by [RosstheRoss](https://github.com/RosstheRoss))
+- Fixes membership transitions from `knock` to `join` in `knock_restricted` rooms
+- Incremental syncs now batch querying events (Contributed by [recht](https://github.com/recht))
+- Move `/joined_members` back to the clientAPI/roomserver, which should make bridges happier again
+- Backfilling from other servers now only uses at max 100 events instead of potentially thousands
+
+## Dendrite 0.13.5 (2023-12-12)
+
+Upgrading to this version is **highly** recommended, as it fixes several long-standing bugs in
+our CanonicalJSON implementation.
+
+### Fixes
+
+- Convert unicode escapes to lowercase (gomatrixserverlib)
+- Fix canonical json utf-16 surrogate pair detection logic (gomatrixserverlib)
+- Handle negative zero and exponential numbers in Canonical JSON verification (gomatrixserverlib)
+- Avoid logging unnecessary messages when unable to fetch server keys if multiple fetchers are used (gomatrixserverlib)
+- Issues around the device list updater have been fixed, which should ensure that there are always
+  workers available to process incoming device list updates.
+- A panic in the `/hierarchy` endpoints used for spaces has been fixed (client-server and server-server API)
+- Fixes around the way we handle database transactions (including a potential connection leak)
+- ACLs are now updated when received as outliers
+- A race condition, which could lead to bridges instantly leaving a room after joining it, between the SyncAPI and
+  Appservices has been fixed
+
+### Features
+
+- **Appservice login is now supported!**
+- Users can now kick themselves (used by some bridges)
+
+## Dendrite 0.13.4 (2023-10-25)
+
+Upgrading to this version is **highly** recommended, as it fixes a long-standing bug in the state resolution
+algorithm.
+
+### Fixes:
+
+- The "device list updater" now de-duplicates the servers to fetch devices from on startup. (This also 
+  avoids spamming the logs when shutting down.)
+- A bug in the state resolution algorithm has been fixed. This bug could result in users "being reset"
+  out of rooms and other missing state events due to calculating the wrong state.
+- A bug when setting notifications from Element Android has been fixed by implementing MSC3987
+
+### Features
+
+- Updated dependencies
+  - Internal NATS Server has been updated from v2.9.19 to v2.9.23
+
+## Dendrite 0.13.3 (2023-09-28)
+
+### Fixes:
+
+- The `user_id` query parameter when authenticating is now used correctly (contributed by [tulir](https://github.com/tulir))
+- Invitations are now correctly pushed to devices
+- A bug which could result in the corruption of `m.direct` account data has been fixed 
+
+### Features
+
+- [Sliding Sync proxy](https://github.com/matrix-org/sliding-sync) can be configured in the `/.well-known/matrix/client` response
+- Room version 11 is now supported
+- Clients can request the `federation` `event_format` when creating filters
+- Many under the hood improvements for [MSC4014: Pseudonymous Identities](https://github.com/matrix-org/matrix-spec-proposals/blob/kegan/pseudo-ids/proposals/4014-pseudonymous-identities.md)
+
+### Other
+
+- Dendrite now requires Go 1.20 if building from source
+
+## Dendrite 0.13.2 (2023-08-23)
+
+### Fixes:
+
+- Migrations in SQLite are now prepared on the correct context (transaction or database)
+- The `InputRoomEvent` stream now has a maximum age of 24h, which should help with slow start up times of NATS JetStream (contributed by [neilalexander](https://github.com/neilalexander))
+- Event size checks are more in line with Synapse
+- Requests to `/messages` have been optimized, possibly reducing database round trips
+- Re-add the revision of Dendrite when building from source (Note: This only works if git is installed)
+- Getting local members to notify has been optimized, which should significantly reduce memory allocation and cache usage
+- When getting queried about user profiles, we now return HTTP404 if the user/profiles does not exist
+- Background federated joins should now be fixed and not timeout after a short time
+- Database connections are now correctly re-used
+- Restored the old behavior of the `/purgeRoom` admin endpoint (does not evacuate the room before purging)
+- Don't expose information about the system when trying to download files that don't exist
+
+### Features
+
+- Further improvements and fixes for [MSC4014: Pseudonymous Identities](https://github.com/matrix-org/matrix-spec-proposals/blob/kegan/pseudo-ids/proposals/4014-pseudonymous-identities.md)
+  - Lookup correct prev events in the sync API
+  - Populate `prev_sender` correctly in the sync API
+  - Event federation should work better
+- Added new `dendrite_up` Prometheus metric, containing the version of Dendrite
+- Space summaries ([MSC2946](https://github.com/matrix-org/matrix-spec-proposals/pull/2946)) have been moved from MSC to being natively supported
+- For easier issue investigation, logs for application services now contain the application service ID (contributed by [maxberger](https://github.com/maxberger))
+- The default room version to use when creating rooms can now be configured using `room_server.default_room_version`
+
+## Dendrite 0.13.1 (2023-07-06)
+
+This releases fixes a long-standing "off-by-one" error which could result in state resets. Upgrading to this version is **highly** recommended.
+
+When deduplicating state events, we were checking if the event in question was already in a state snapshot. If it was in a previous state snapshot, we would 
+then remove it from the list of events to store. If this happened, we were, unfortunately, skipping the next event to check. This resulted in 
+events getting stored in state snapshots where they may not be needed. When we now compared two of those state snapshots, one of them
+contained the skipped event, while the other didn't. This difference possibly shouldn't exist, resulting in unexpected state resets and explains
+reports of missing state events as well.
+
+Rooms where a state reset occurred earlier should, hopefully, reconcile over time.
+
+### Fixes:
+
+- A long-standing "off-by-one" error has been fixed, which could result in state resets
+- Roomserver Prometheus Metrics are available again
+
+### Features
+
+- Updated dependencies
+  - Internal NATS Server has been updated from v2.9.15 to v2.9.19

+- Support for connecting to appservices listening on unix sockets has been added (contributed by [cyberb](https://github.com/cyberb))
+- Admin APIs for token authenticated registration have been added (contributed by [santhoshivan23](https://github.com/santhoshivan23))
+- Initial support for [MSC4014: Pseudonymous Identities](https://github.com/matrix-org/matrix-spec-proposals/blob/kegan/pseudo-ids/proposals/4014-pseudonymous-identities.md)
+  - This is **highly experimental**, things like changing usernames/avatars, inviting users, upgrading rooms isn't working
+
+### Fixes
+
+- `m.upload.size` is now optional, finally allowing uploads with unlimited file size
+- A bug while resolving server names has been fixed (contributed by [anton-molyboha](https://github.com/anton-molyboha))
+- Application services should only receive one invitation instead of 2 (or worse), which could result in state resets previously
+- Several admin endpoints are now using `POST` instead of `GET`
+- `/delete_devices` now uses user-interactive authentication
+- Several "membership" (e.g `/kick`, `/ban`) endpoints are using less heavy database queries to check if the user is allowed to perform this action
+- `/3pid` endpoints are now available on `/v3` instead of the `/unstable` prefix
+- Upgrading rooms ignores state events of other users, which could result in failed upgrades before
+- Uploading key backups with a wrong version now returns `M_WRONG_ROOM_KEYS_VERSION`
+- A potential state reset when joining the same room multiple times in short sequence has been fixed
+- A bug where we returned the full event as `redacted_because` in redaction events has been fixed
+- The `displayname` and `avatar_url` can now be set to empty strings
+- Unsafe hotserving of files has been fixed (contributed by [joshqou](https://github.com/joshqou))
+- Joining new rooms would potentially return "redacted" events, due to history visibility not being set correctly, this could result in events being rejected 
+- Backfilling resulting in `unsuported room version ''` should now be solved
+

+
+- Huge refactoring of Dendrite and gomatrixserverlib
+
+## Dendrite 0.12.0 (2023-03-13)
+
+### Features
+
+- The userapi and keyserver have been merged (no actions needed regarding the database)
+- The internal NATS JetStream server is now using logrus for logging (contributed by [dvob](https://github.com/dvob))
+- The roomserver database has been refactored to have separate interfaces when working with rooms and events. Also includes increased usage of the cache to avoid database round trips. (database is unchanged)
+- The pinecone demo now shuts down more cleanly
+- The Helm chart now has the ability to deploy a Grafana chart as well (contributed by [genofire](https://github.com/genofire))
+- Support for listening on unix sockets has been added (contributed by [cyberb](https://github.com/cyberb))

+- A possible DoS issue related to relations has been fixed (reported by [sleroq](https://github.com/sleroq))
+- When backfilling events, errors are now ignored if we still could fetch events
+
+### Other
+

+- Many under the hood pinecone improvements
+- Publishing rooms is now possible again
+
+## Dendrite 0.11.0 (2023-01-20)

+* The Helm chart now uses the `$.Chart.AppVersion` as the default image version to pull, with the possibility to override it (contributed by [genofire](https://github.com/genofire))
+
+## Dendrite 0.10.9 (2023-01-17)
+
+### Features

+
+### Features
+
+* The built-in NATS Server has been updated to version 2.9.8
+* A number of under-the-hood changes have been merged for future virtual hosting support in Dendrite (running multiple domain names on the same Dendrite deployment)
+
+### Fixes
+

+* The deduplication of the `"timeline"` and `"state"` sections in `/sync` is now performed after applying history visibility, so state events should not be dropped unexpectedly
+* The `prev_batch` token returned by `/sync` is now calculated after applying history visibility, so that the pagination boundaries are correct
+* The room summary membership counts in `/sync` should now be calculated properly in more cases
+* A false membership leave event should no longer be sent down `/sync` as a result of retiring an accepted invite (contributed by [tak-hntlabs](https://github.com/tak-hntlabs))
+* Presence updates are now only sent to other servers for which the user shares rooms
+* A bug which could cause a panic when converting events into the `ClientEvent` format has been fixed
+
+## Dendrite 0.10.6 (2022-11-01)

+We use a script called "Are We Synapse Yet" which checks Sytest compliance rates. Sytest is a black-box homeserver
 test rig with around 900 tests. The script works out how many of these tests are passing on Dendrite and it

+updates with CI. As of January 2023, we have 100% server-server parity with Synapse, and the client-server parity is at 93% , though check
 CI for the latest numbers. In practice, this means you can communicate locally and via federation with Synapse
 servers such as matrix.org reasonably well, although there are still some missing features (like SSO and Third-party ID APIs).
