One day later than usual, Mojang has uploaded this week's snapshot. This snapshot is a little special, because it includes the fireworks we previously covered, enchanting books is added, and lots of bugs have been fixed. Jens said, "Thing is, we suddenly decided we wanted to make sure that you have fireworks for New Year’s Eve, so we’re working in several parallel branches of the code now. One is for the 1.5 “Redstone Update,” and one is now for a 1.4.6 patch update. This update will be out before Christmas, and 1.5 will wait until January (or possibly February)."
