v14.0.20 Latest

v14.0.19

New Features

  • Connected AI assistants can now join a game with its shareable join code, so you can invite them by simply sharing the code in chat.

Bug Fixes

  • A stale game lobby no longer blocks a connected AI assistant from joining a new game, only a game that is actually being played counts as busy.
v14.0.18

New Features

  • AI assistants connected to mssgs can now be invited to play games with you: they accept one game at a time and take their turns on their own, just for fun.

  • When a game ends you can jump straight into a rematch, and you can switch between your active games from the lobby.
  • The game lobby Invite button now opens a friends picker to invite someone by direct message instead of only copying a join code.
  • The Monopoly board has a cleaner, more finished look.
v14.0.17

Bug Fixes

  • AI integrations: live message events reach the local MCP mirror again, new messages were silently dropped, freezing read_channel, get_new_messages and the SSE stream for connected AI clients.
  • AI integrations: the AI now marks a channel read only when it consumes a message that mentions it (or reads a DM), instead of clearing unreads on every poll.
v14.0.16

New Features

  • Play games together in direct messages: Battleship, Four in a Row, Checkers, Snake, and Monopoly with up to four players.
  • Monopoly plays on an isometric 3D board with your avatars as tokens: buy streets, build houses and hotels, and land on Free Parking to win the pot that taxes and chance cards feed.
  • Checkers now follows authentic draughts (dammen) rules: mandatory captures, crowned double dams that fly across the board, and a choice of an 8×8 or full 10×10 board.
  • Game hosts can tune each match with room options, such as board size and starting capital.
  • Game invites appear as live cards in chat that update with the lobby state, and finished games post a result card with a snapshot of the final board.
  • An ongoing game can be minimized to a draggable pill so you can keep chatting while you play, and lobbies show a QR code for quickly joining from another device.
  • Game rooms can be opened for public spectating, and a Watch button in the conversation header lets you watch a friend’s ongoing game.
  • Members now show a Playing indicator while they are in a game.
  • Finished voice calls in direct messages now leave a call summary card in the conversation.
  • Share photos, videos, and links into mssgs directly from other macOS apps, with an in-app picker to choose the destination conversation.

Bug Fixes

  • Bot embed cards with a server-hosted image now display the image correctly.
  • Direct-message voice calls are more reliable: answering, canceling, and ending a call now stay in sync on both sides, and you are prompted to end the call when the other person leaves.

  • A member’s Playing indicator now clears immediately when their game or custom status ends.
  • The one-time-view toggle in the share picker now shows a clear active state.

  • Connected AI tools are notified in realtime when a direct-message call starts ringing, so they can react right away.
