I've also changed a few of the items. The items added in 1.4 have dark outlines, and most foods have their outlines once again. The nether star is now blue, to match the beacon, whose beam is now a bright white. Nether brick is now a dark concrete, to avoid completely destroying builds made prior to 1.4.6. An alternate terrain is included which has the default nether brick if you don't like concrete. Item frames are black, and so are command blocks, which are now made of black plastic instead of whatever they were before.
