This is a bug fix release, with a change to theme and plugins button location to help new players switch HUDs.
Changes:
- Uses the system 7 theme for Marathon rather than the old theme with nonobvious buttons
- Moves the Plugins button up to the main Preferences menu
- Makes transparent liquids a disabled plugin by default, to match classic Marathon 2 and Infinity experience
Bug Fixes:
- Fixes a crash in software mode
- Fixes tostring for some Lua enums
- Only plays breathing sounds and O2 warnings for the current player
- Partial fix for destroyable scenery showing the wrong frame
