Java Edition 13w39b

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

This version was previously removed from the launcher for some time, but was added back in September 2018.

Changes

 * Added an alert telling the player to use item names when you spawn item in using its ID, due to soon becoming deprecated
 * Added an alert in the main menu warning the player of a change in the "far future", which will result in Minecraft requiring a OpenGL feature set version of 2.1 or higher
 * The "Diamonds to you" achievement can now be obtained by throwing a diamond at a zombie with the "CanPickUpLoot" NBT-tag
 * A minecart with command block now 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
