# 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)
### 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)
### Features
* Various tables belonging to the user API will be renamed so that they are namespaced with the `userapi_` prefix
* Note that, after upgrading to this version, you should not revert to an older version of Dendrite as the database changes **will not** be reverted automatically
* The backoff and retry behaviour in the federation API has been refactored and improved
### Fixes
* Private read receipt support is now advertised in the client `/versions` endpoint
* Private read receipts will now clear notification counts properly
* A bug where a false `leave` membership transition was inserted into the timeline after accepting an invite has been fixed
* Some panics caused by concurrent map writes in the key server have been fixed
* The sync API now calculates membership transitions from state deltas more accurately
* Transaction IDs are now scoped to endpoints, which should fix some bugs where transaction ID reuse could cause nonsensical cached responses from some endpoints
* The length of the `type`, `sender`, `state_key` and `room_id` fields in events are now verified by number of bytes rather than codepoints after a spec clarification, reverting a change made in Dendrite 0.9.6
## Dendrite 0.10.3 (2022-10-14)
### Features
* Event relations are now tracked and support for the `/room/{roomID}/relations/...` client API endpoints have been added
* Support has been added for private read receipts
* The built-in NATS Server has been updated to version 2.9.3
### Fixes
* The `unread_notifications` are now always populated in joined room responses
* The `/get_missing_events` federation API endpoint should now work correctly for rooms with `joined` and `invited` visibility settings, returning redacted events for events that other servers are not allowed to see
* The `/event` client API endpoint now applies history visibility correctly
* Read markers should now be updated much more reliably
* A rare bug in the sync API which could cause some `join` memberships to be incorrectly overwritten by other memberships when working out which rooms to populate has been fixed
* The federation API now correctly updates the joined hosts table during a state rewrite
## Dendrite 0.10.2 (2022-10-07)
### Features
* Dendrite will now fail to start if there is an obvious problem with the configured `max_open_conns` when using PostgreSQL database backends, since this can lead to instability and performance issues
* More information on this is available [in the documentation](https://matrix-org.github.io/dendrite/installation/start/optimisation#postgresql-connection-limit)
* Unnecessary/empty fields will no longer be sent in `/sync` responses
* It is now possible to configure `old_private_keys` from previous Matrix installations on the same domain if only public key is known, to make it easier to expire old keys correctly
* You can configure either just the `private_key` path, or you can supply both the `public_key` and `key_id`
### Fixes
* The sync transaction behaviour has been modified further so that errors in one stream should not propagate to other streams unnecessarily
* Rooms should now be classified as DM rooms correctly by passing through `is_direct` and unsigned hints
* A bug which caused marking device lists as stale to consume lots of CPU has been fixed
* Users accepting invites should no longer cause unnecessary federated joins if there are already other local users in the room
* The sync API state range queries have been optimised by adding missing indexes
* It should now be possible to configure non-English languages for full-text search in `search.language`
* The roomserver will no longer attempt to perform federated requests to the local server when trying to fetch missing events
* The `/keys/upload` endpoint will now always return the `one_time_keys_counts`, which may help with E2EE reliability
* The sync API will now retrieve the latest stream position before processing each stream rather than at the beginning of the request, to hopefully reduce the number of round-trips to `/sync`
## Dendrite 0.10.1 (2022-09-30)
### Features
* The built-in NATS Server has been updated to version 2.9.2
### Fixes
* A regression introduced in 0.10.0 in `/sync` as a result of transaction errors has been fixed
* Account data updates will no longer send duplicate output events
## Dendrite 0.10.0 (2022-09-30)
### Features
* High performance full-text searching has been added to Dendrite
* Search must be enabled in the [`search` section of the `sync_api` config](https://github.com/matrix-org/dendrite/blob/6348486a1365c7469a498101f5035a9b6bd16d22/dendrite-sample.monolith.yaml#L279-L290) before it can be used
* The search index is stored on the filesystem rather than the sync API database, so a path to a suitable storage location on disk must be configured
* Sync requests should now complete faster and use considerably less database connections as a result of better transactional isolation
* The notifications code has been refactored to hopefully make notifications more reliable
* A new `/_dendrite/admin/refreshDevices/{userID}` admin endpoint has been added for forcing a refresh of a remote user's device lists without having to modify the database by hand
* A new `/_dendrite/admin/fulltext/reindex` admin endpoint has been added for rebuilding the search index (although this may take some time)
### Fixes
* A number of bugs in the device list updater have been fixed, which should help considerably with federated device list synchronisation and E2EE reliability
* A state resolution bug has been fixed which should help to prevent unexpected state resets
* The deprecated `"origin"` field in events will now be correctly ignored in all cases
* Room versions 8 and 9 will now correctly evaluate `"knock"` join rules and membership states
* A database index has been added to speed up finding room memberships in the sync API (contributed by [PiotrKozimor](https://github.com/PiotrKozimor))
* The client API will now return an `M_UNRECOGNIZED` error for unknown endpoints/methods, which should help with client error handling
* A bug has been fixed when updating push rules which could result in `database is locked` on SQLite
## Dendrite 0.9.9 (2022-09-22)
### Features
* Dendrite will now try to keep HTTP connections open to remote federated servers for a few minutes after a request and attempt to reuse those connections where possible
* This should reduce the amount of time spent on TLS handshakes and often speed up requests to remote servers
* This new behaviour can be disabled with the `federation_api.disable_http_keepalives` option if needed
* A number of dependencies have been updated
### Fixes
* A bug where the roomserver did not correctly propagate rewritten room state to downstream components (like the federation API and sync API) has been fixed, which could cause issues when performing a federated join to a previously left room
* Event auth now correctly parses the `join_authorised_via_users_server` field in the membership event content
* Database migrations should no longer produce unique constraint errors at Dendrite startup
* The `origin` of device list updates should now be populated correctly
* Send-to-device messages will no longer be dropped if we fail to publish them to specific devices
* The roomserver query to find state after events will now always resolve state if there are multiple prev events
* The roomserver will now return no memberships if querying history visibility for an event which has no state snapshot
* The device list updater will now mark a device list as stale if a requesting device ID is not known
* Transactions sent to appservices should no longer have accidental duplicated transaction IDs (contributed by [tak-hntlabs](https://github.com/tak-hntlabs))
## Dendrite 0.9.8 (2022-09-12)
### Important
* This is a **security release** to fix a vulnerability where missing events retrieved from other servers did not have their signatures verified in all cases, affecting all versions of Dendrite before 0.9.8.

* A number of minor database transaction issues have been fixed, particularly for assigning NIDs in the roomserver, cleaning up device keys and cleaning up notifications
* The database query for finding shared users in the sync API has been optimised, using significantly less CPU time as a result
## Dendrite 0.9.6 (2022-09-01)
### Features
* The appservice API has been refactored for improved performance and stability
* The appservice database has been deprecated, as the roomserver output stream is now used as the data source instead

* The handling of event soft-failure has been improved on the roomserver input by no longer applying rejection rules and still calculating state before the event if possible
* The federation `/state` and `/state_ids` endpoints should now return the correct error code when the state isn't known instead of returning a HTTP 500
* The federation `/event` should now return outlier events correctly instead of returning a HTTP 500
* A bug in the federation backoff allowing zero intervals has been corrected
* The `create-account` utility will no longer error if the homeserver URL ends in a trailing slash

## Dendrite 0.9.4 (2022-08-19)
### Fixes
* A bug in the roomserver around handling rejected outliers has been fixed

## Dendrite 0.9.2 (2022-08-12)
### Features
* Dendrite now supports history visibility on the `/sync`, `/messages` and `/context` endpoints
* It should now be possible to view the history of a room in more cases (as opposed to limiting scrollback to the join event or defaulting to the restrictive `"join"` visibility rule as before)
* The default room version for newly created rooms is now room version 9
* New admin endpoint `/_dendrite/admin/resetPassword/{userID}` has been added, which replaces the `-reset-password` flag in `create-account`

## Dendrite 0.9.0 (2022-08-01)
### Features
* Dendrite now uses Ristretto for managing in-memory caches
* Should improve cache utilisation considerably over time by more intelligently selecting and managing cache entries compared to the previous LRU-based cache
* Defaults to a 1GB cache size if not configured otherwise
* The estimated cache size in memory and maximum age can now be configured with new [configuration options](https://github.com/matrix-org/dendrite/blob/e94ef84aaba30e12baf7f524c4e7a36d2fdeb189/dendrite-sample.monolith.yaml#L44-L61) to prevent unbounded cache growth

* Fixed destination queue performance issues as a result of missing indexes, which speeds up outbound federation considerably
* A bug which could cause the `/register` endpoint to return HTTP 500 has been fixed
## Dendrite 0.8.6 (2022-05-26)
### Features
* Room versions 8 and 9 are now marked as stable

* The `create-account` tool should now work properly when the database is configured using the global connection pool
## Dendrite 0.8.4 (2022-05-10)
### Fixes

## Dendrite 0.8.3 (2022-05-09)
### Features
* Open registration is now harder to enable, which should reduce the chance that Dendrite servers will be used to conduct spam or abuse attacks
* Dendrite will only enable open registration if you pass the `--really-enable-open-registration` command line flag at startup
* If open registration is enabled but this command line flag is not passed, Dendrite will fail to start up
* Dendrite now supports phone-home statistic reporting
* These statistics include things like the number of registered and active users, some configuration options and platform/environment details, to help us to understand how Dendrite is used
* This is not enabled by default — it must be enabled in the `global.report_stats` section of the config file
* Monolith installations can now be configured with a single global database connection pool (in `global.database` in the config) rather than having to configure each component separately
* This also means that you no longer need to balance connection counts between different components, as they will share the same larger pool
* Specific components can override the global database settings by specifying their own `database` block
* To use only the global pool, you must configure `global.database` and then remove the `database` block from all of the component sections of the config file
* A new admin API endpoint `/_dendrite/admin/evacuateRoom/{roomID}` has been added, allowing server admins to forcefully part all local users from a given room
* The sync notifier now only loads members for the relevant rooms, which should reduce CPU usage and load on the database
* A number of component interfaces have been refactored for cleanliness and developer ease
* Event auth errors in the log should now be much more useful, including the reason for the event failures
* The forward extremity calculation in the roomserver has been simplified
* A new index has been added to the one-time keys table in the keyserver which should speed up key count lookups
### Fixes
* Dendrite will no longer process events for rooms where there are no local users joined, which should help to reduce CPU and RAM usage
* A bug has been fixed in event auth when changing the user levels in `m.room.power_levels` events
* Usernames should no longer be duplicated when no room name is set
* Device display names should now be correctly propagated over federation

* The media `/config` endpoint will no longer return a maximum upload size field if it is configured to be unlimited in the Dendrite config
* The server notices room will no longer produce "User is already joined to the room" errors
* Consumer errors will no longer flood the logs during a graceful shutdown
* Sync API and federation API consumers will no longer unnecessarily query added state events matching the one in the output event
* The Sync API will no longer unnecessarily track invites for remote users
## Dendrite 0.8.2 (2022-04-27)
### Features
* Lazy-loading has been added to the `/sync` endpoint, which should speed up syncs considerably
* Filtering has been added to the `/messages` endpoint
* The room summary now contains "heroes" (up to 5 users in the room) for clients to display when no room name is set
* The existing lazy-loading caches will now be used by `/messages` and `/context` so that member events will not be sent to clients more times than necessary
* The account data stream now uses the provided filters
* The built-in NATS Server has been updated to version 2.8.0
* The `/state` and `/state_ids` endpoints will now return `M_NOT_FOUND` for rejected events
* Repeated calls to the `/redact` endpoint will now be idempotent when a transaction ID is given
* Dendrite should now be able to run as a Windows service under Service Control Manager
### Fixes
* Fictitious presence updates will no longer be created for users which have not sent us presence updates, which should speed up complete syncs considerably
* Uploading cross-signing device signatures should now be more reliable, fixing a number of bugs with cross-signing
* All account data should now be sent properly on a complete sync, which should eliminate problems with client settings or key backups appearing to be missing
* Account data will now be limited correctly on incremental syncs, returning the stream position of the most recent update rather than the latest stream position
* Account data will not be sent for parted rooms, which should reduce the number of left/forgotten rooms reappearing in clients as empty rooms
* The TURN username hash has been fixed which should help to resolve some problems when using TURN for voice calls (contributed by [fcwoknhenuxdfiyv](https://github.com/fcwoknhenuxdfiyv))
* Push rules can no longer be modified using the account data endpoints
* Querying account availability should now work properly in polylith deployments
* A number of bugs with sync filters have been fixed
* A default sync filter will now be used if the request contains a filter ID that does not exist
* The `pushkey_ts` field is now using seconds instead of milliseconds
* A race condition when gracefully shutting down has been fixed, so JetStream should no longer cause the process to exit before other Dendrite components are finished shutting down
## Dendrite 0.8.1 (2022-04-07)

* Joined and invite user counts are now sent in the `/sync` room summaries
* Queued federation and stale device list updates will now be staggered at startup over an up-to 2 minute warm-up period, rather than happening all at once
* Memory pressure created by the sync notifier has been reduced
* The EDU server component has now been removed, with the work being moved to more relevant components
### Fixes
* It is now possible to set the `power_level_content_override` when creating a room to include power levels over 100
* `/send_join` and `/state` responses will now not unmarshal the JSON twice

### Fixes
* State resolution v2 performance has been improved dramatically when dealing with large state sets
* The roomserver no longer processes outlier events if they are already known
* A SQLite locking issue in the previous events updater has been fixed
* The client API `/state` endpoint now correctly returns state after the leave event, if the user has left the room
* The client API `/createRoom` endpoint now sends cumulative state to the roomserver for the initial room events
* The federation API `/send` endpoint now correctly requests the entire room state from the roomserver when needed
* Some internal HTTP API paths have been fixed in the user API (contributed by [S7evinK](https://github.com/S7evinK))
* A race condition in the rate limiting code resulting in concurrent map writes has been fixed
* Each component now correctly starts a consumer/producer connection in monolith mode (when using Kafka)
* State resolution is no longer run for single trusted state snapshots that have been verified before
* A crash when rolling back the transaction in the latest events updater has been fixed
* Typing events are now ignored when the sender domain does not match the origin server
* Duplicate redaction entries no longer result in database errors
* Recursion has been removed from the code path for retrieving missing events
* `QueryMissingAuthPrevEvents` now returns events that have no associated state as if they are missing
* Signing key fetchers no longer ignore keys for the local domain, if retrieving a key that is not known in the local config
* Federation timeouts have been adjusted so we don't give up on remote requests so quickly
* `create-account` no longer relies on the device database (contributed by [ThatNerdyPikachu](https://github.com/ThatNerdyPikachu))
### Known issues
* Old events can incorrectly appear in `/sync` as if they are new when retrieving missing events from federated servers, causing them to appear at the bottom of the timeline in clients
