Dendrite 0.9.9

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)
