1.2.6 (Bug-fix Update Pt. 5)	December 3, 2010	Added /kill command for SMP, which deals 1,000 points damage to the player. Added small lakes and rare lava pools, both on the surface and randomly in caves. In SMP, Players connecting to a server or respawning are invulnerable for three seconds. Bug Fixes: Items no longer get used when opening chests (i.e. food being eaten, lava being poured out, etc.) Breaking a boat in a certain fashion no longer causes it to drop 4 times the normal amount. Patched client to prevent duplicated entities. The join server page now remembers the port as well as the IP. Fixed a bug where joining a server on a specific port caused the client to forget all keybindings. Fixed a crash bug when destroying the vehicle from under a player.
1.2.5 (Bug-fix Update Pt. 4)	December 1, 2010	Bug Fixes: SMP Fixes: Fixed a memory leak bug in the server. Riding carts and boats now works properly when you travel long distances.

New bugs: Difficulty is reset to Normal upon updating Players and mobs spawn duplicates.
1.2.4_01	November 30, 2010	Bug Fixes: Minecraft can spawn all mobs, not just creepers. A player no longer gets snowballs when entering a SMP server. New Bugs: Doors in SMP often open either the top or bottom half instead of acting as a whole.
1.2.4 (Bug-fix Update Pt. 3)	November 30, 2010	The SMP join server screen now remembers the latest entered IP. Bug Fixes Leaving sneak mode no longer rapidly plays all the step sounds that it silenced during the sneak. SMP Fixes: Swords and other weapons now deal damage properly. Added proper hurt animations and sounds to mobs and players. Fixed dead players logging in as invisible ghosts. Made arrows visible and deal damage. No more infinite free arrows. Hoes now produce proper Seeds. Creepers now animate before exploding Explosions animate properly. Server logging now appends to server.log rather than overwriting it. Buttons, levers, and pressure plates animate properly when activated Fixed minecarts and pigs moving twice as fast as they should when ridden. Increased chunk saving frequency on the server. You can now see sneaking players. Names of sneaking players aren’t visible through walls, and are visible a much shorter distance. New Bugs: The only aggressive mob that is able to spawn are Creepers A player receives snowballs when entering a SMP server as a result of left-in debug code
1.2.3_04 (Bug-fix Update Pt. 2)	November 26, 2010	Bug Fixes: Fixed all known SMP player respawn bugs. Fixed vanishing mobs.
1.2.3_02	November 25, 2010	Fixed most of SMP player respawn bugs, including the ghost bug.
1.2.3_01	November 24, 2010	Template:1.2.3 01 Fixed single player mode. Fixed infinite looping by disabling leaf decay.
1.2.3 (Bug-fix Update Pt. 1)	November 24, 2010	Re-introduced leaf decay New server configuration settings: pvp, true by default. If this is set to false, players can’t hurt other players. spawn-monsters, true by default. Set to false to remove all monsters. spawn-animals, also true by default.

Damage now correctly given for falling damage, drowning, burning Made eating food restore health Implemented respawning for dead players Visible hurt animations for players and mobs Visible fire on players and mobs Fixed the block re-spawning bug in SMP Players traveling in boats and minecarts long distances now receive terrain updates in SMP New Bugs: Single player mode is completely broken Leaf decay causes infinite looping, causing the game to freeze. Mobs in multiplayer are much harder to kill than in single player mode. Mobs are sometimes invisible and thus invincible, and can still attack players. When a player dies, their newly-respawned body does not appear to other players. These "ghost" players were unable to pick up items, though otherwise able to interact with the world normally from their perspective. This was fixed with the ghosting player log back onto the server or by editing the player's .dat file.
1.2.2	November 10, 2010	Pressing F4 on your keyboard will spawn a Nether portal Lava flows further in The Nether Zombie Pigmen forgive the player after time Main Menu now has texture-pack selection menu for easy texture-pack switching.

However reloading the world will cause you to fall in lava. In SMP, Boats and Minecarts are indestructible without the use of TNT. In SMP, hitting sheep will drop cloth, but it can't be picked up. However, casting with a fishing rod will knock obtainable cloth, but the sheep will still appear woolen. Getting out of a boat in SMP is difficult and buggy Pressing F4 will spawn Nether Portals (later fixed)

In 3rd person mode (F5), pressing F1 will create a view looking back at the player's own face. Bug Fixes: Fixed bugs in SMP Redstone performance updated Door animation fixes Several performance bugs fixed Rails no longer cause a crash New Bugs: Leaf decay is broken. Going higher than 62 meters above sea level in SMP causes the character to be stuck to the sky. Save file size is calculated incorrectly after you visit the Nether, usually to 0.0MB Fake chunks now render after 32,000,000 blocks away from spawn. On rare occasions, an item will not appear in the inventory when picked up and no more of this item will show up in the inventory. This can be fixed by closing the client.

1.0.6_01	July 17, 2010	Fixed stuttering after death bug Leaves decay again when not connected to either the ground or to a tree trunk Tweaked monster and animal spawning a bit. The game probably is quite a bit more difficult now. Boats can be placed on land, and won’t break if you hit land unless you’re going above a certain speed Boats spawn water splash particles only when going fast enough to break Boats turn much nicer New Bugs: If you stand on your boat underwater, the boat does not rise anymore and you will stay still underwater.

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. Breaking a minecart or a boat while inside will cause you to fall through one block of ground.

1.0.3	July 6, 2010	The pathfinder now works for hills. Except for spiders. Generally more convincing mob idling behavior. They’ll stand still more, looking around at their surroundings Monster sounds Ambient cave noises
1.0.2_01	July 6, 2010	Redstone torch, not gates, only signal into blocks above them or next to them Redstone dust won't connect through solid blocks diagonally down Art tweaks to the dust Walking on red dust no longer breaks it. Red dust now gives off particles.
