I don't know if you guys care/know but they added cocoa plants, writable books, a large biome option(world type) and merged ssp and smp. I just think it's epic because I've been waiting to write in books forever.
Alot of it seems really good, I'm curious to see exactly how they'll implement the ssp and smp merge with the mod api they've been promising to give us
Merging the two game modes isn't exactly something that makes sense, they should of been merged to start with. What this does mean is that everything from now on is automatically tested for Multiplayer. Remember when SMP first came out and half the crap didn't work. Nope not any more.
All the bug fixes are fantastic though, Although they should of been fixed a lot earlier.
