Today's update fixes a few miscellaneous bugs, including some lingering issues in the Linux build.

• Linux now saves to $XDG_DATA_HOME instead of always saving to "~/.local/share". If you have $XDG_DATA_HOME set to something other than "~/.local/share" you may have to move your save files manually.
• Fixed a serious memory leak by rewriting our audio system. If you notice any new sound-related bugs, please let us know!
• Fixed a bug where the area select tool could be used to move blocks into inputs and outputs, where you're normally not allowed to build.
• Fixed a Linux-specific bug that caused players to sometimes go out of bounds when climbing stairs.
• Fixed a Linux-specific bug that caused some audio logs and cinematic sequences to crash the game.
