Additions:
The biggest addition by far is the new ores and metals.
Authentication updated to use the modern servers.
Skins updated to use modern servers. Alex skins are supported.
Books, a mix of modern and my own code.
The Brick Oven.
A server list for connecting to servers, basically taken from older versions of modern.
A static structure generator. Currently this generates a couple rare surface buildings and some new dungeons, but there will be more in the future.
Shears can now harvest long grass and dead bushes.
Secret music discs.
New background and main menu music.
Quite a few new building blocks.
Cooked eggs.
Blue mushrooms.
Dynamite.
Bookshelves can now contain items.
The seed of a world is displayed on the F3 screen.
Old sounds.
Wrenches.
Telescopes.
FOV Slider.

Changes:
There have been quite a few crafting changes from vanilla.
Massive changes to caves. They just keep on going.
Some of the old textures are added back in.
A new, fuller look for grass.
Zombies now uncommonly drop a leather tunic or leather pants.
Mobs spawned from monster spawners do not drop anything.
Plants in general will grow slower, but not by much. I plan to make this slower yet.
Worlds are saved to "NFCSaves" in the Minecraft directory.
Trees cannot generate with just one log block under the leaves, it needs to be at least 2 now.
As mentioned earlier, stairs and slabs can be placed in various orientations.
