I get excited about play testing new content and reporting any problems for you guys...
Anyway, I'm going over the issue tracker. Apparently today, the bug where going between dimensions changes your selected item slot is fixed. A side effect is it also retains which slot you had when logging in and out of a server. Also, apparently the Wither accidentally destroying it's own Nether Star through some means like having shot as it died, so the shots land on the star, was fixed. Also, boats will now place in the direction you place them instead of in the same direction, forcing you to turn. Also, that bug where you get glitched leave blocks that don't stack was fixed. And pressing 1-9 to take items out of the furnace will give XP as intended. And tree leaves no longer repalce slabs when grown off a tree.
