A silent multiplayer issue needed a proper fix. Players entering lobbies without updating were quietly breaking the network for everyone else, and that required a real solution rather than a workaround.
NEW FEATURES
Lobbies now include a version control system. Players receive a warning when the room is full or when their version does not match the host's.
BUG FIXES
In 0.0.79, the "Bug Report", "I'm Stuck", and "Main Menu" buttons were locked for an unknown reason. That has been corrected.
If you ran into that button issue last patch, it should be gone now.
