Changelog

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 and 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 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 (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)
• Fully read markers are now implemented in the client API (contributed by 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)
• 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)

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
