 # 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
-
-## Dendrite 0.13.0 (2023-06-30)
-
-### Features
-
-- Results in responses to `/search` now highlight words more accurately and not only the search terms as before
-- 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
-
-### Other
-
-- Huge refactoring of Dendrite and gomatrixserverlib

-Yes
+Yes, [Space Summaries](https://github.com/matrix-org/matrix-spec-proposals/pull/2946) were merged into the Matrix Spec as of 2022-01-17 however, they are still treated as an MSC (Matrix Specification Change) in Dendrite.
