Java Edition 14w26a

14w26a is the twenty-ninth snapshot released for 1.8. This snapshot is the first after a decision to release snapshots on Wednesdays rather than on Thursdays.

It is strongly advised to make a backup of a world before using this snapshot, because of block-corrupting problems that were not corrected until 14w26c.

A potential means of recovering corrupted worlds using MCEdit was made available by a Reddit user, on this thread.

Additions

 * Commands
 * Can replace items in any inventory, including the inventories of mobs such as zombies
 * Full syntax:
 * Example:  will give all the zombies iron swords
 * Example:  will put 4 clownfish in the players first hotbar slot
 * Example:  will put a redstone block in the 6th slot of a container 1 block beneath the player
 * Debug Mode world type
 * Useful for resource pack makers
 * Hold and cycle through "World Type" to select it
 * Spectator mode recommended to avoid crashes (you can use creative mode too without any effect on some machines)
 * All possible blocks with all possible data values are generated
 * They are arranged in a grid across height y=70, with a barrier floor at y=60
 * Blocks placed are deleted, and blocks destroyed are restored
 * There is a special generator option preventing this. It is called "debug_all_block_states". If you change this to "flat" or "default" in NBTexplorer, you will be able to interact with the world. Only for a short period though, on most machines there will be lots of lag or the game might crash. (Not recommended to play survival on)
 * Gamerules
 * If set to false, player-run commands will not show a success message

Changes

 * Commands
 * Now has a  argument (sub-command, only works when used with execute)
 * Allows the  command to run only if a block is detected at a specific location relative to the target
 * Example:
 * Now has an  argument
 * Similar to the  argument, but can be used to add (or remove) a certain number of blocks to the world border distance
 * Negative numbers can be used to remove blocks
 * Example:  will shrink the world border width by 75 blocks
 * Block limit changed from 4096 to 32768 blocks
 * Command Blocks
 * X/O button next to "Last output" in commandblock to turn off the last output string
 * Customized world type
 * Has an ocean monument toggle
 * Resources
 * Reworked 3D resources, adding the possibility of new blocks with multiple textures
 * Swampland
 * Changed generation of the marsh-like areas
 * Furnace
 * Empty furnaces will now only accept fuel and empty buckets in the fuel slot
 * Item Frames
 * The wood part of the frame now uses the oak texture rather than the birch texture
 * BlockStates
 * Switched to only/mostly using BlockStates in the code, though not all block combinations are BlockStates yet
 * Block models
 * Instead of specifying uvs, you can now choose textures to be projected onto the model
 * Nether Portal
 * Removed the item form of nether portal blocks.
 * End Portal
 * Removed the item form of end portal blocks.
