We have released version 1.13.1 that patches some incorrect behavior and improves stability.

• Multiplayer: Crash when two clients join a game
• Multiplayer: Crash when joining a multiplayer game using the Vanilla appearance profile
• Multiplayer: Missing busy mode transition frame when joining a game
• UI: Using keyboard bindings when a popup is open in the UI (e.g., pressing F11 to toggle screen when the DE menu is open in the task bar)
• Audio: Momentary pause during MIDI playback when looping (fixed in upgraded SDL and SDL_mixer in the Windows package)
• OS X: Shell uses the wrong UI font
• Added a "-nodiscovery" command line option to prevent Doomsday from looking for running servers on the LAN
