Java Edition 13w39b

13w39b is the ninth snapshot for 1.7.2, and was released to fix some of the bugs and crashes in the 13w39a snapshot.

This version has been removed from the launcher for quite a bit, then it was added back in September 2018.

Changes

 * An alert appears telling you to use item names when you spawn an item in using its ID, as they will soon become deprecated
 * A different alert in the main menu warns you of a change in the far future, which will result in Minecraft requiring at least the OpenGL 2.1 feature set
 * The "Diamonds to you" achievement can be obtained by throwing a diamond at a zombie with the "CanPickUpLoot" NBT-tag
 * Minecart with Command Block only activates every 4 ticks (2 redstone ticks) when on a powered Activator Rail
 * Changed the item name (the name used in place of block and item IDs in the command) of the Minecart with Command Block from minecraft:hopper_command_block to minecraft:command_block_minecart
