Java Edition 16w39a

16w39a is the seventh snapshot released for 1.11.

Blocks

 * Observer
 * Ported from the Pocket and Windows 10 editions.
 * May have slight behavior differences due to how redstone works in the Java edition compared to Pocket and Windows 10 Edition.
 * Outputs a redstone signal when it detects a block update.
 * Normal BUDS still remain.


 * Shulker Box
 * Crafted in a Crafting Table as a single column, with a Chest in the middle row and a Shulker Shell both above and below the chest.
 * In this snapshot, there is a bug making you unable to craft it in the right and left columns.
 * Works similar to a chest, but keeps its content when broken.
 * If it has any content inside, it will drop itself in Creative mode as well.
 * Can not be placed inside another Shulker Box.
 * When hovered over in your inventory, it will show up to 5 slots of its content.
 * Breaks when being pushed by a piston.
 * Uses the same opening and closing animations as the Shulker.
 * Can be placed on different sides of a block to open in different directions.
 * When opening, its hitbox changes from 1 block to 1.5 blocks in its opening direction.
 * Because of this, it will not open if there is a block of any kind within the closest half-block area in its opening direction.
 * Can be dyed in any of the available dye colors.
 * Dyed Shulker Boxes have a slightly darker bottom part than the normal one.
 * In this snapshot, there is a bug with obtaining the dyed versions, so currently it is only possible to get them through Creative or commands.
 * Dispensers will place the block on the ground.
 * Can be mined with anything, but is mined faster with a pickaxe.
