Hello Saorlan,

The biggest patches include changes in terrain. The latest patch has all the terrain heights increased and all zones modified to add more detail and special areas.

Other large patches have included creatures or revised animations and textures (we revised all textures for better memory usage at one point).

Changes to things like the crafting system or other features are small patches, as most of the data is already patched out. For example all of the data for buildings, boulders and caves, that will be seen in game soon, were patched out a while ago.
