Receives lobby chat through osu!'s real-time notification WebSocket instead of repeatedly polling for messages.
Faster commands/chat responses with fewer osu!
API requests.
One shared live chat connection serves every active lobby.
Reconciles chat history on startup/reconnect and falls back to HTTP polling if the live connection drops; the announcement describes this as preventing missed commands.
Three lobbies can run fully headless with one referee connection; osu!lazer need not remain open or switch rooms.
Each lobby independently sends/receives chat while Discord controls and status channels continue working.
API requests are primarily reserved for room state, player data, beatmap checks, messages and normal lobby operations rather than chat checks.
The announcement describes this as a major step toward more stable multi-lobby hosting.
