Java Edition 13w05a

13w05a is the seventh snapshot released for Java Edition 1.5, which adds snow layers.

13w05a was reuploaded shortly after release.

Blocks

 * Snow
 * 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 have 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.

Blocks

 * Beacons
 * Increased 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).


 * 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.


 * Stairs
 * Improved lighting.
 * No longer prevent sprinting.

Items

 * Bonemeal
 * Everything now randomly takes 2-3 uses to fully grow.

Command format

 * Scoreboard
 * 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.
