Changes

 * The ability to select multiple resource packs at once.
 * Resource packs at the top take precedence over those below.
 * Allows for non-manual merging of textures from multiple packs, a sound pack and a different texture pack, etc.
 * Flint and Steel is now a shapeless recipe.
 * A Creeper will explode after igniting it with a flint and steel.
 * Several lighting issues fixed.
 * A lot fewer "black spots" in the terrain generator.
 * Torch bugs in strongholds and mineshafts have been fixed.
 * Rewrite of several option screens.
 * A completely new options menu.
 * A new "Select Resource Pack" menu.
 * Rewrote Key Config.
 * Function and sprint keys can be changed.
 * By default, sprinting can be activated by holding down the left control key. In Creative mode, this can also be done while flying.
 * The original sprinting controls (double-tap forward or double-tap backward while holding down forward) still function.
 * Smooth mouse, formerly available by pressing F8, will now use F4 by default.
 * The volume of in game music, Jukebox and Note Block music, hostile mobs, passive mobs, players, weather, blocks/environment, and the master volume can now all be modified separately.
 * Written Books can now be cloned the same way maps can, but by using Book and Quills instead of Empty Maps

 * Item Frames
 * Now drop the item inside them when punched, then drop themselves if they are punched when empty
 * Will display the name of the item they hold (if it is custom named) when looked at up close
 * Sugar Cane changes color depending on biome (Texture is unchanged, adding biome color makes it appear different)
 * Rewrite of the achievements and statistics system
 * Now ties in with the scoreboard system - added 744 new objective criteria that were previously tracked with statistics and achievements
 * Are now per world/server
 * Achievements screen can now be zoomed in and out using the mouse wheel.
 * Achievements don't appear on the achievements screen if more than five achievements need to be achieved first (i.e. "DIAMONDS!" doesn't appear until "Getting Wood" is achieved).
 * Data for a block, item, or mob doesn't appear in their respective tab in the Statistics screen unless the player has crafted/placed/mined that block, crafted/used/depleted that item, or killed/was killed by that mob.
 * New achievements: Repopulation, Adventuring Time, The Beginning?, The Beginning., and Beaconator
 * New statistics: Distance by Horse, Junk Fished, and Treasure Fished
 * New scoreboard functions
 * Can now use statistics to create objectives; anything that statistics can track can be used as an objective (can also track achievements)
 * This is the reason why statistics/achievements were changed to be stored per world/server
 * The /give command can now give items to players with custom names and lore
 * It can also give enchanted items.
 * Example: /give  {display:{Name:"",Lore:["",""]},ench:[0:{id: ,lvl: }]}
 * It can also give items with custom NBT tags, such as SkullOwner to obtain the Head of a specific player
 * This removes the necessity to use an NBT editing program to obtain these items.
 * Attribute modifiers have been added to the /give command (not completely investigated as of yet).
 * Example: To give a diamond sword with +50 Attack Damage to the nearest player, use the command /give @p 276 1 0 {AttributeModifiers:[0:{AttributeName:"generic.attackDamage",Name:"generic.attackDamage",Amount:50,Operation:0,UUIDLeast:894654,UUIDMost:2872}]}
 * This enables the possibility of additional attributes to items using commands without the use of an NBT editing program.
 * Command blocks now show what command it ran recently.
 * The /time set day command now sets the time to 1000 instead of 0
 * Increased fog distance
 * Weighted Pressure Plates now output a signal relative to the amount of entities on them, always starting at 1 signal strength if any entities are present

 * Stone is generated more frequently than in the previous versions, even outside of Extreme Hills+ Biomes.
 * Biomes have been put into four main categories
 * Snow-covered

 * Medium
 * Dry/warm
 * Biomes will attempt to avoid getting placed next to a biome that is too different to itself
