New Bugs:
Upon dying the framerate slowly drops to an unplayable rate. The game will no longer save after death, causing you to see yourself dead whenever you load the save. The only workaround is to modify the save file with a tool like NBTedit.
Breaking a minecart while inside will cause you to fall through one block of ground.
If you are riding your boat while the boat is above a block you fall through one block of ground
Destroying Snow blocks yields 4-6 Snowballs. Allowing for infinite amounts of snow (as blocks only take 4 snowballs to make)
boat bug
Cacti blocks generate in winter maps.
