## Dendrite 0.6.5 (2022-03-04)
### Features
* Early support for push notifications has been added, with support for push rules, pushers, HTTP push gateways and the `/notifications` endpoint (contributions by [danpe](https://github.com/danpe), [PiotrKozimor](https://github.com/PiotrKozimor) and [tommie](https://github.com/tommie))
* Spaces Summary (MSC2946) is now correctly supported (when `msc2946` is enabled in the config)
* All media API endpoints are now available under the `/v3` namespace
* Profile updates (display name and avatar) are now sent asynchronously so they shouldn't block the client for a very long time

* Support added for the `/context` endpoint, which should help clients to render quote-replies correctly
* Accounts now have an optional account type field, allowing admin accounts to be created
* Server notices are now supported
* Refactored the user API storage to deduplicate a significant amount of code, as well as merging both user API databases into a single database
* The account database is now used for all user API storage and the device database is now obsolete
* For some installations that have separate account and device databases, this may result in access tokens being revoked and client sessions being logged out — users may need to log in again
* The above can be avoided by moving the `device_devices` table into the account database manually
* Guest registration can now be separately disabled with the new `client_api.guests_disabled` configuration option
* Outbound connections now obey proxy settings from the environment, deprecating the `federation_api.proxy_outbound` configuration options

* Room joins will now fall back to federation if the local room state is insufficient to create a membership event
* Create events are now correctly filtered from federation `/send` transactions
* Excessive logging when federation is disabled should now be fixed
* Dendrite will no longer panic if trying to retire an invite event that has not been seen yet
* The device list updater will now wait for longer after a connection issue, rather than flooding the logs with errors
* The device list updater will no longer produce unnecessary output events for federated key updates with no changes, which should help to reduce CPU usage
* Local device name changes will now generate key change events correctly
* The sync API will now try to share device list update notifications even if all state key NIDs cannot be fetched
* An off-by-one error in the sync stream token handling which could result in a crash has been fixed
* State events will no longer be re-sent unnecessary by the roomserver to other components if they have already been sent, which should help to reduce the NATS message sizes on the roomserver output topic in some cases
* The roomserver input API now uses the process context and should handle graceful shutdowns better
* Guest registration is now correctly disabled when the `client_api.registration_disabled` configuration option is set
* One-time encryption keys are now cleaned up correctly when a device is logged out or removed
* Invalid state snapshots in the state storage refactoring migration are now reset rather than causing a panic at startup

* Fixed a problem where rejected events could result in rolled back database transactions
* Avoided a potential race condition on fetching latest events by using the room updater instead
* Processing events from `/get_missing_events` will no longer result in potential recursion
* Federation events are now correctly generated for updated self-signing keys and signed devices

* Requires the version 2 configuration file — please see the new `dendrite-config.yaml` sample config file
* Kafka and Naffka are no longer supported as of this release
* The roomserver is now responsible for fetching missing events and state instead of the federation API
* Removes a number of race conditions between the federation API and roomserver, which reduces duplicate work and overall lowers CPU usage
* The roomserver input API is now strictly ordered with support for asynchronous requests, smoothing out incoming federation significantly
* Consolidated the federation API, federation sender and signing key server into a single component
* If multiple databases are used, tables for the federation sender and signing key server should be merged into the federation API database (table names have not changed)
* Device list synchronisation is now database-backed rather than using the now-removed Kafka logs
### Fixes
* The code for fetching missing events and state now correctly identifies when gaps in history have been closed, so federation traffic will consume less CPU and memory than before

### Features
* Performance of initial/complete syncs has been improved dramatically
* State events that can't be authed are now dropped when joining a room rather than unexpectedly causing the room join to fail
* State events that already appear in the timeline will no longer be requested from the sync API database more than once, which may reduce memory usage in some cases
### Fixes

### Fixes
* Updating forward extremities will no longer result in so many unnecessary state snapshots, reducing on-going disk usage in the roomserver database
* Pagination tokens for `/messages` have been fixed, which should improve the reliability of scrollback/pagination
* Dendrite now avoids returning `null`s in fields of the `/sync` response, and omitting some fields altogether when not needed, which should fix sync issues with Element Android

* A new roominfo cache has been added, which results in less database hits in the roomserver
* Prometheus metrics have been added for sync requests, destination queues and client API event send perceived latency
### Fixes
* Event IDs are no longer recalculated so often in `/sync`, which reduces CPU usage
* Sync requests are now woken up correctly for our own device list updates
* The device list stream position is no longer lost, so unnecessary device updates no longer appear in every other sync

## Dendrite 0.2.1 (2020-10-22)
### Fixes
* Forward extremities are now calculated using only references from other extremities, rather than including outliers, which should fix cases where state can become corrupted ([#1556](https://github.com/matrix-org/dendrite/pull/1556))
* Old state events will no longer be processed by the sync API as new, which should fix some cases where clients incorrectly believe they have joined or left rooms ([#1548](https://github.com/matrix-org/dendrite/pull/1548))
* More SQLite database locking issues have been resolved in the latest events updater ([#1554](https://github.com/matrix-org/dendrite/pull/1554))
* Internal HTTP API calls are now made using H2C (HTTP/2) in polylith mode, mitigating some potential head-of-line blocking issues ([#1541](https://github.com/matrix-org/dendrite/pull/1541))
* Roomserver output events no longer incorrectly flag state rewrites ([#1557](https://github.com/matrix-org/dendrite/pull/1557))
* Notification levels are now parsed correctly in power level events ([gomatrixserverlib#228](https://github.com/matrix-org/gomatrixserverlib/pull/228), contributed by [Pestdoktor](https://github.com/Pestdoktor))
* Invalid UTF-8 is now correctly rejected when making federation requests ([gomatrixserverlib#229](https://github.com/matrix-org/gomatrixserverlib/pull/229), contributed by [Pestdoktor](https://github.com/Pestdoktor))
## Dendrite 0.2.0 (2020-10-20)
### Important
* This release makes breaking changes for polylith deployments, since they now use the multi-personality binary rather than separate binary files
* Users of polylith deployments should revise their setups to use the new binary - see the Features section below
* This release also makes breaking changes for Docker deployments, as are now publishing images to Docker Hub in separate repositories for monolith and polylith
* New repositories are as follows: [matrixdotorg/dendrite-monolith](https://hub.docker.com/repository/docker/matrixdotorg/dendrite-monolith) and [matrixdotorg/dendrite-polylith](https://hub.docker.com/repository/docker/matrixdotorg/dendrite-polylith)
* The new `latest` tag will be updated with the latest release, and new versioned tags, e.g. `v0.2.0`, will preserve specific release versions
* [Sample Compose configs](https://github.com/matrix-org/dendrite/tree/master/build/docker) have been updated - if you are running a Docker deployment, please review the changes
* Images for the client API proxy and federation API proxy are no longer provided as they are unsupported - please use [nginx](docs/nginx/) (or another reverse proxy) instead
### Features
* Dendrite polylith deployments now use a special multi-personality binary, rather than separate binaries
* This is cleaner, builds faster and simplifies deployment
* The first command line argument states the component to run, e.g. `./dendrite-polylith-multi roomserver`
* Database migrations are now run at startup
* Invalid UTF-8 in requests is now rejected (contributed by [Pestdoktor](https://github.com/Pestdoktor))
* Fully read markers are now implemented in the client API (contributed by [Lesterpig](https://github.com/Lesterpig))
* Missing auth events are now retrieved from other servers in the room, rather than just the event origin
* `m.room.create` events are now validated properly when processing a `/send_join` response
* The roomserver now implements `KindOld` for handling historic events without them becoming forward extremity candidates, i.e. for backfilled or missing events
### 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
