telegram

Breaking changes

• Prometheus metric names are now prefixed with bridge_
• An entrypoint script is no longer automatically generated. This won't affect most users, as python -m mautrix_telegram has been the official way to start the bridge for a long time.

Added

• Support for logging in by scanning a QR code from another Telegram client (#399).
• Automatic backfilling of old messages when creating portals (#476).
• Automatic backfilling of missed messages when starting bridge (#477).
• Option to update m.direct list when using double puppeting.
• PNG thumbnails for animated stickers when converted to webm (#467).
• Support for receiving ephemeral events pushed directly with MSC2409 (requires Synapse 1.22 or higher).

Improved

• Switched end-to-bridge encryption to mautrix-python instead of a hacky matrix-nio solution.
• End-to-bridge encryption no longer requires login_shared_secret, it uses MSC2778 instead (requires Synapse 1.21 or higher).
• The bridge info state event is now updated whenever the chat name or avatar changes.
• Double puppeting is no longer limited to users on the same homeserver as the bridge (#520).
• Delivery receipts are no longer sent in unencrypted private chat portals, as the bridge bot is usually not present in them (#483).

Fixed

• File captions are now sent as a separate message like photo captions.
• The relaybot no longer drops Telegram messages with commands.
• Bridging events of a user whose power level is malformed (i.e. a string instead of an integer) now works (#526).

• Fixed deleting messages from Matrix (#498)
• Fixed Alpine edge dependencies in Docker image

Note: this release is not on PyPI, as the only changes were a mautrix-python update (v0.5.8) and a fix to the Docker image.

• Fixed starting bridge for the first time failing due to not registering the bridge bot (#479)
• Updated Docker image to Alpine 3.12

Added

• Command for backfilling room history from Telegram.
• ARM64 support in docker images.
• Optional end-to-bridge encryption support (#403). See page on wiki for more info.
• allow_avatar_remove config option to sync removed avatars from Telegram instead of leaving the last known avatar forever.
• private_chat_portal_meta config option to set private chat portal room name/avatar explicitly. This is enabled implicitly if end-to-bridge encryption is enabled.
• Config options to send delivery receipts and error notices.
• Bridging for Telegram dice roll messages.
• Implemented MSC2346: Bridge information state event for newly created rooms

• Moved private information to trace log level (#321)

• Bumped maximum Telethon version to 1.14
• Possibly fixed infinite loop of avatar changes when using double puppeting (#464)

• Moved private information to trace log level (#321)
