The new features are:
An isometric engine that supports two different isometric grids, units, and transitions on the tiles.
A gui module with some various and simple widgets
An image module that adds some new resize transformations, animated images, and loading functions.
A pixelperfect library that supports fast, perfect collisions, hitmasks can be gotten form surfaces or animated images.
A font module that just makes fonts easier to deal with.
The current isometric engine is fast enough for turn based stuff, but other-wise you would need too small of maps or too small of a screen to be able to do real-time stuff very well. So there are some speed/memory patches planned for the near-future.
Any bug reports would be greatly appreciated.
