 This should contain all the major changes.
 For minor stuff, refer to the commit log of the repository.
 
+0.3.1: (released on 2011-11-09)
+- Fix frustum culling (previous versions have rendered too much stuff that is not actually visible (about 180 degrees, while should have been more like 100.))
+- Add occlusion culling (improves performance a lot)
+- Add “3d clouds” on/off checkbox in main menu
+- Add “opaque water” on/off checkbox
+- Fix some random minor stuff
+- Turn mipmapping off (This makes far-away textures a bit noisier but better looking)
+- Add Command-line signal handler for Windows (contributed by SpeedProg)
+- Fix network layer segmentation fault introduced in 0.3.dev-20111021
+- Fix water-glass and water-lava and lava-glass surfaces
