Many of the things in the changelog are apparently in here.

Thank you for posting that. I was thinking that it would be pretty strange to go to the trouble of coding all this stuff and then not make it available just for April Fools. Some of the features are actually pretty cool.
That's racist. If your trying to be funny, your not. If your trying to be insulting, that also didn't work. If your trying to be racist, you have succeeded.
On topic, I watch a video about this "update" and thought it was serious until I saw the pink wither. To be honest, a lot of these joke features would be wonderful to Minecraft! Like the stained glass, the new stairs I saw, and the pigs exploding into bacon would be quiet funny.
