Trivia

 * This is the only version in which the player is able to truly hold blocks, rather than items corresponding to blocks. Endermen are the only mob to have this ability in normal versions.
 * When a spawner is picked up and placed back down, it will lose its block data and become a pig spawner.
 * With the help of a tamed horse, the player can shift - right click it and they will see their inventory. The player can put items in the slots with the help of offhand.
 * Despite the snapshot's name, the player can still move items to the offhand, and, therefore, carry two blocks at a time.
 * Placing offhand items in creative mode does not consume the item, as usual, even though a main hand item is consumed in creative mode.
 * The player's usual  data is still accessible using commands like, , and , but, apart from the armor slots and offhand, this data doesn't do anything.
 * Using the command will always place items into the players hands. If the command is used while the player is already holding something, the new item will be thrown onto the ground (and place itself if it is a block).
 * The command will claim that   even if the player is holding something, if they had empty   data.
 * The command reveals that the hand slot is using the NBT tag , which is the same tag as for items held by Endermen and which will always be a   if the target player is holding something that is not a normal block.
 * In creative mode, loading saved hotbars still modifies this data.
 * Picking up mobs modifies the player's  data, which is usually always empty.
 * Certain blocks, like fire, end or nether portal blocks, and end gateways, do not display properly when held or thrown — these are invisible in first person, and in some cases also in third person or also when thrown.
 * Blocks that do not normally have an item form can now be placed directly, like portal blocks.
 * Using to place a   with an ID that represents a block will cause it to display the block as if misaligned on the vertical axis, rotated so that the top points south, and with its faces culled to match what would be culled if it were a normal block, e.g.  for a "grass" block.
