Overall Optimization: the program now has better memory usage, allowing for less chance of graphical errors to occur on older systems, or when quickly switching between multiple large levels. And, as a result, also has faster startup times.
Updated Audio System: better system for loading audio files allowing for a smaller memory footprint while giving the ability to utilize more sound and music files in-game.
Updated Dynamic Music Engine: the music track selection system has been changed to give the player a wider range of music while playing the game.
Graphical Changes: very slight change to some textures in the dwarven tileset.
