Java Edition 13w05a

13w05a is the seventh snapshot released for 1.5.

Additions

 * Fully implemented multiple snow heights
 * Drops one snowball for every layer of snow
 * Each level of snow has its own height collision
 * The topmost layer of snow does not have collision, so the player is always slightly sunken in the snow
 * Visually, four layers of snow is the same height as a slab. However, five layers of snow has the same collision height as a slab
 * Crafting recipe is 3 snow blocks in a row to create 6 snow layers
 * For each thin layer of snow crafted, the player loses exactly half the snowballs required to produce it

Changes

 * Improved the scoreboard system
 * Added team mechanics including custom name colors, friendly fire options and objective tracking per team instead of per player
 * Added a new display type – displays value below nametags
 * Added a new criterion – health, ranging from 0 to 20
 * Increased beacon range
 * Effects are infinite upwards with the beam.
 * 1 layer: 41 blocks diameter (previously 33)
 * 2 layers: 61 blocks (previously 49)
 * 3 layers: 81 blocks (previously 65)
 * 4 layers: 101 blocks (previously 81)
 * Improved Stairs
 * Improved lighting
 * Stairs no longer prevent sprinting
 * Rebalanced bonemeal
 * Everything now usually takes 2–3 uses to fully grow, but it's random
 * Comparator
 * Now uses the 8s bit on block 149 to represent its powered state, rather than a separate block ID, 150. Block 150 is deprecated.
