credits.txt, earlyplayers.txt and win.txt added to /title/ in minecraft.jar.
Attempting to sleep in a Bed while hostile mobs are nearby will display the message: "You may not rest now, there are monsters nearby"
Crafting tables can now be mined faster with an axe.
Added ending titles.
Mined stairs of any materials will drop a stair block now instead of a block form of its material.
Added "Particles" setting in Video Settings. Has three possible states: "All", rendering all particle effects, "Decreased", rendering half of all particle effects, and "Minimal", rendering no particle effects.
Added Dragon Egg; currently seems to serve no practical purpose, however.
Changes to the mining time of many minerals, including red stone ore, stone brick, nether brick, iron bars, iron door, mob spawners, and obsidian, making their mining times much faster.
'Efficiency' effect on pickaxes now affects all applicable materials, including obsidian, nether brick, etc.
Tools not suited to digging a certain block can be faster than digging by hand, e.g. a pickaxe can dig dirt faster than by hand, but not faster than by shovel.
More minor changes to textures, this time to:
Side texture of Grass, adhering to dirt texture change in previous pre-release
Additionally, the Sun and Moon have square textures again. The phases of the Moon are also square.
More finished Enderdragon boss fight.
"Boss Health" Meter appears on the middle top part of the screen in the same purple hue as the Enderdragon.
Leaves behind a fountain like bedrock structure with the Enderdragon Egg sitting on top and has another Ender Portal to return to the players spawn point/ bed.
Ender Crystal added, an object which sits atop of a bedrock block that is diamond shaped that has 2 squares spinning on their axis with a point at the center that fires a healing beam at the Enderdragon when within range, and can be destroyed with a melee or hit with an arrow, causing an explosion. They appear on all the Obsidian Spikes in The End.
The explosion caused by Ghast Fireballs seems to have a new sound effect(?)
Shooting arrows, using items and hitting mobs no longer uses up items/durability in creative.
Lily Pads are now a solid block.
Ferns, Tall Grass and Lily Pads are now available in the creative inventory.
Unnecessary block versions of Cake and Sugar Cane removed from creative inventory.
Enchantment Tables now take time to mine, instead of one punch.
"Mods and Texture Packs" changed to "Texture Packs".
Repeater clocks no longer get stuck when unloading the chunk.
Placing fences under farmland doesn't stop it from turning back into dirt.
Minecart with Furnace is able to push empty Minecart at any direction. Texture rotates wrong, though.
Baby Sheep from dyed parents are now born dyed as well instead of white.
Notable Bugs: (Complete bug list)
Armor durability seems to be back to being much tougher, akin to 1.8.
Wooden doors cannot be opened directly by clicking.
You lose all experience levels/points after the credits.
Snow Biomes do not generate properly
Redstone Signals can no longer be pushed through glowstone using a repeater. (This is due to glowstone now being considered a transparent block.)
While in F5 Mode, Lilypads will appear grey.
The "Particles" option in Video Settings overlaps the warning when playing on far render distance with 32-bit java.
