14w11a is the seventeenth snapshot released for 1.8.

Additions

 * Mobs

 * Appearance is similar to a silverfish's appearance, except they are purple and emit ender particles.
 * Endermen are hostile towards them.
 * Will sometimes spawn in place of an Enderman teleporting away.
 * Will despawn after 2 minutes.
 * Will spawn with a 5 percent chance when an Ender pearl lands.
 * Not yet completed - endermites may have something to do with dragon eggs
 * Model will be changed in the next Snapshot

Changes

 * Minecarts
 * Changed minecart physics
 * Minecarts now go faster and farther
 * Improved collision and position handling
 * Minecarts can derail at corners if going too fast, as well as refuse to go uphill
 * Minecart with Furnace
 * They now give a much greater boost to other minecarts
 * When powered, they can move on non-powered rails without decelerating
 * Minecart with TNT
 * Minecart with TNT explosions no longer stack.
 * Mob AI
 * Silverfish will stop occasionally before moving again (similar to most mobs)
 * Slimes seem to jump a bit more randomly
 * Witches, skeletons, zombies, zombie pigmen and creepers now run away from exploding creepers
 * Endermen walk slightly faster
 * Debug screen
 * On the right hand side, a display shows up if you are looking at a block, giving various pieces of information and NBT data about it.
 * Looking at a door and redstone shows you the state of the block
 * Door: which way it is facing, if it is open, which half you are looking at, if it is powered, and what side the hinge is
 * Redstone: power direction (up, down, side, none) for all compass directions (north, south, east, west) and power level
 * Not 100% complete, data for a lot of blocks still missing
 * Blocks
 * Now internally use states instead of metadata
 * Metadata will still be used for a while
 * Block states of the block being looked at will now be displayed on the F3 menu - Examples: redstone, door
 * Internally, metadata no longer needs to be calculated out of the 4 bit data value, instead the values of specified properties can now be easily gotten and set
 * Block models
 * Converted fence gates, brewing stands
 * Lighting now works with models (most models for some users)
 * Graphics
 * Dropped items now face the player in all three directions on fast graphics
