Nex and Siondream have been hard at work refactoring the tile-map APIs. You can follow their progress on this branch on Github.
The most noticeable change is the removal of the tiled preprocessor. No longer do you have to preprocess your tilemaps. Other changes include support for both Tiled maps as well as Gleed2D maps. You can also easily create your own maps programmatically or write a loader for your own maps format real quick. We also support isometric tilemaps now and you can change the maps on the fly. Animated tiles are something that Nex may or may not work on.
Check out the tests in the branch linked to above. We’ll go live in a few days, after finishing up some docs and merging into master.
