Some notes:
Almost all int x, int y, int z parameters have been changed to BlockPos class
ForgeDirection has been removed, replaced by net.minecraft.util.EnumFacing.
All FML classes have moved from packet cpw.mods.fml to net.minecraftforge.fml
Fluid Rendering has been disabled for the time being, to be re-evaulated and a test mod created for it.
Minecraft now uses a Model based system for rendering blocks and Items. The intention is to expand the model format to better suit modder's needed once it is evaulated.
As such, The model loaders from Forge have been removed, to be replaced by expanding vanilla's model format.
Metadata has been extracted out in Minecraft to IBlockState, which holds a list of properties instead of magic number metadata. DO NOT listen to the fearmongering, you can do EVERYTHING with block states you could previously with metadata.
Stencil Bits are disabled entirely by for the main Display, Modders must enable and recreate the FrameBuffer if they wish to use Stencil Bits.
You can see it's not working by requesting the ore IDs from lapis, and you'll see the name "dye" is missing (and that's the one registered using the wildcard).
Fixed it by inverting the order of the item stack parameters.
If recipe is multiple levels of inheritance from Object and not categorized, cls=cls.getSuperclass(); needs to be repeated more than once. It must therefore be moved to inside the while loop.
Block placement/interaction
Tesselator crash due to wrong mapping
Missing isreplaceable check in world.canPlaceAt
Small foratting/logging cleanup
Temporarly commented out efficancy changes till I implement it.
