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.

Non-mob entities

 * Minecart with command block
 * Now only activates every 4 ticks (2 redstone ticks) when on a powered activator rail.
 * Changed the ID from minecraft:hopper_command_block to minecraft:command_block_minecart.

Command format

 * Syntax
 * Added an alert telling the player to use item names when you spawn item in using its ID, due to soon becoming deprecated.

General

 * Achievements
 * The "Diamonds to you" achievement can now be obtained by throwing a diamond at a zombie with the "CanPickUpLoot" NBT-tag.


 * Main Menu
 * Added an alert in the main menu warning the player of a change in the far future, which will result in Minecraft requiring an OpenGL feature set version of 2.1 or higher.
