Changelog

unreleased

Add config option mention_only_always_for_named to allow treating rooms that look like named rooms (named or with alias) as mention only automatically.
Allow editing outbound replies and messages. If a previous !edit or !message command is edited, it will be sent out as an edit replacing the original outbound reply or message. (issue)
When receiving an event the bot cannot decrypt, the event will now be stored for later. When keys are received later matching any stored encrypted events, a new attempt will be made to decrypt them.
Add possibility to log to a Matrix room.
Add config option to replace confirmation messages with reactions. (issue)
Added support for relaying media. (issue)

Don't send a welcome message to non-dm rooms on join.
Use pip-tools to lock dependencies.
Refactor Dockerfile and rename main launcher from middleman-bot to main.py. This was done to unify the two Elokapina bots, Bubo and Middleman.
Exit loudly if we fail to join the management room.
Notify sender to try again if we fail to relay a message to the management room.
Never send "unknown command" responses to rooms.
Upgrade Docker image to Python 3.10 and libolm 3.2.10

Ensure case is ignored when looking for display name mentions (issue)
Better duplicate events cache control in callbacks to avoid ram usage growth over time.
Management room commands now ignore any reply prefix on the message, allowing fixing command typos.
Force charset_normalizer dependency logs to warning level to avoid spammy info logs about probing the chaos when the Matrix server is unavailable.
Fix issue where replying to a previous !reply would send the reply to the room that the replied to reply originally targeted.
Don't crash if room membership event has no prev_content property.

Allow configuring mention only rooms. This allows joining Middleman to rooms with lots of discussion. Messages in a room in this list will only be relayed to the management room if the Middleman user is mentioned in the message.
Add a new command !message to send messages to other rooms. This can only be used in the management room. Works with both ID and alias.
Ensure m.notice messages are also relayed (ref #18)

Messages relayed into the management room and replies to the senders are now standard text messages, not notices.
Messages relayed into the management room now also have the room name if there is one.
When joining a room the bot will now also message the management room about the join.
Don't format relayed messages in italic since it breaks formatting of relayed messages (ref #16)

Move the welcome message logic from the invite to a member joined event (ref #1)
Don't resend welcome message on display name change (ref #14)
Fix some Markdown rendering issues by switching to CommonMark module (ref #11)
Send error message back to management room on unknown room ID (ref #13)
