Fixes
From released versions before 1.8
 * – Mobs treat any layered snow as non-solid
 * – Scoreboard: player does not appear in sidebar after setting initial score to zero
 * – 32000 Command block character limit only works as a 16000 character limit within Minecraft
 * – Knockback distance incorrect, depends on login order

From the 1.8 snapshots
 * – Interacting with invalid villagers crashes the game
 * – Surface dungeons generating without spawner, chests, and most of floor
 * – Leaves, Block of Redstone, TNT and Glowstone cause suffocation damage
 * – Wither destroying barrier block
 * – Mob Dungeon spawning without floor / with broken chests / overwritten spawner
 * – Slime spawning
 * – Leads don't show knot on fence posts and cannot be right clicked
 * – Chest not openable with item frame on, standing too close
 * – Cats and dogs teleporting into leaves and rails, causing them to suffocate
 * – clears sidebar for other scoreboard objectives
 * – Staying outside border makes you unable to move at all
 * – Sliders have incorrect values causing world to never be created
 * – footstep, hugeexplosion and largeexplode particles don't appear
 * – doesn't work on a player that's not on a scoreboard, but also does work
