A warning

This snapshot should be considered "fairly experimental, dude". From a scale of 1-10 where 1 is experimental and 10 is stable, this is a tentative 3.

Back up your worlds before trying them in this snapshot. Don't expect worlds played in this snapshot to work in future snapshots. Don't expect worlds played in last weeks snapshot to work in this weeks snapshot.

Resource packs

They broke in last weeks snapshot, but we forgot to update the format number so they didn't warn you in game. We've fixed that and now every outdated resource pack will warn you if you try to use it.
