The new build contains two new locations, each about half a mile in diameter: "The Barrens" and "Martha's Marsh".
The new build is also streamlined to reduce memory usage and build size (100 MB smaller despite more content).
There's at least one known glitch: in "The Barrens", the game pauses briefly as you move through the location.
It's also possible there may be random glitches in some locations since there was at least one missing item (in the intro) which has been fixed, but it's difficult to determine whether there have been any other random problems that developed.
