 - Optimized sprite processing decreasing the startup time of voxygen (and long freezes when trying
   to enter the world when this hasn't finished).
 - Metadata added to music files. Listen to the soundtrack more easily!
+- Overhauled caves: they're now a multi-layer network spanning the entire world
 
 ### Removed
 - Removed the options for single and cumulated damage.
