■Performance improvements, including reduced CPU, RAM & bandwidth requirements.[citation needed]
■Updated pistons to make them less error-prone, thus they also appear to update slower. This also altered the way pistons work, so you might have to adapt your repeater delays and similar.
■For this change, pistons now take 2 redstone ticks (4 game ticks) to expand, but they still retract instantly.
■Added /debug <start|stop> command.
■Signs are stackable up to 16.
■Crafting them now gives 3 signs instead of 1 with the same recipe.
■Creative mode inventory now shows potion effects.
■Boats now drop the boat item when destroyed by a player.
■Gaining experience from mining ore is now different for each type of ore (mining coal ore will give you the least amount while diamond ore & emerald ore will give the most amount of XP)
■Nether Wart can now grow in the Overworld and The End.
Bug Fixes
■Newly added wooden stairs will now burn.
■Fixed /kill not working.
■Fixed powering specific glitched pistons crashing the game.
■Fixed a visual bug causing pistons to be partially invisible or in the wrong location momentarily.
■Fixed being able to place portals in the Nether in locations where they would end up in illegal locations in the overworld.
■Fixed the game crashing when publishing SP worlds with certain language settings.
■Fixed players on minecarts, boats or pigs and spider jockeys not being displayed in the correct location.
■Fixed a bug with dispensers.
■Fixed /say not accepting some strings form the console, often triggering the help dialogue.
■Fixed being able to transmute blocks to certain data values using an orientation-dependent tripwire bug.
■Fixed drinking potions in creative not consuming the potions, but still giving empty bottles.
■Fixed signs sometimes not saving the text when placing them.

Notable Bugs
■All text on the signs is gone upon loading the world, the text is actually still saved but not shown.
■Additionally, pigs show in all spawners. Both have been confirmed fixed for next snapshot.
■The snapshot may give "Internal Server Error" randomly, kicking the player.
■Quickly reconnecting may result in a crash of the Minecraft client.
■When the server is set to spawn-monsters=false The server still naturally spawns them.
■All blocks above coordinate y:192 may become "phantom blocks" and will disappear. They still exist to where you will have glitchy movements when touching the block.
■This is like the bug with the signs. The blocks still exist and will hopefully visibly reappear in the next snapshot.
■When using a Silk Touch pickaxe on a lighted Redstone Lamp, the drop will be a lighted Redstone Lamp, which is not stackable with the normal/not lighted lamps.
■The fishing rod bug still isn't fixed. The line appears to be at the player's feet when viewed from others in SMP.
