Java Edition 15w31c

15w31c is the third snapshot for 1.9, and was released to fix some bugs and crashes from 15w31a and 15w31b.

Changes

 * The levitation effect no longer overrides the fall damage reduction of the jump boost effect.
 * Offhand slot can now stack whatever item the player is holding by picking them from the ground.
 * The collision height of the grass path block is now the same as the model height, $15/16$ of a block.
 * The item model of all chest variants were reverted back, to be consistent with the rest of blocks.
 * It is believed the previous change was made to make it easier to distinguish between regular and trapped chests.
 * Subsequent ender dragon deaths no longer produce any more eggs.
 * Re-added the nether fog.
