• Started requiring homeservers to advertise Matrix v1.1 support.
  • This bumps up the minimum homeserver versions to Synapse 1.54 and Dendrite 0.8.7. Minimum Conduit version remains at 0.4.0.
  • The bridge will also refuse to start if backfilling is enabled in the config, but the homeserver isn't advertising support for MSC2716. Only Synapse supports backfilling at the moment.
• Added options to make encryption more secure.
  • The encryption -> verification_levels config options can be used to make the bridge require encrypted messages to come from cross-signed devices, with trust-on-first-use validation of the cross-signing master key.
  • The encryption -> require option can be used to make the bridge ignore any unencrypted messages.
  • Key rotation settings can be configured with the encryption -> rotation config.
• Added config validation to make the bridge refuse to start if critical fields like homeserver or database address haven't been changed from the defaults.
• Added option to include captions in the same message as the media to implement MSC2530. Sending captions the same way is also supported and enabled by default.
• Added basic support for fancy business messages (template and list messages).
• Added periodic background sync of user and group avatars.
• Added maximum message handling duration config options to prevent messages getting stuck and blocking everything.
• Changed message send error notices to be replies to the errored message.
• Changed dimensions of stickers bridged from WhatsApp to match WhatsApp web.
• Changed attachment bridging to find the Matrix msgtype based on the WhatsApp message type instead of the file mimetype.
• Updated Docker image to Alpine 3.16.
• Fixed backfill queue on SQLite.
