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.

World generation

 * Debug mode world type
 * Useful for resource pack makers.
 * Hold and cycle through "World Type" to select it.
 * Spectator mode recommended to avoid crashes (creative mode can also be used 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 the player changes this to "flat" or "default" in NBTexplorer, the player 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).

Command format

 * 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.

 * Gamerules
 * If set to false, player-run commands will not show a success message.
 * If set to false, player-run commands will not show a success message.

Blocks

 * General
 * Switched to only/mostly using blockstates in the code, though not all block combinations are blockstates yet.


 * Command blocks
 * X/O button next to "Last output" in command block to turn off the last output string.


 * 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.


 * Stems
 * Changed model from Attached Stem 14w25a.png to Attached Stem JE2.png

World generation

 * Customized world type
 * Has an ocean monument toggle.


 * Swampland
 * Re-added marsh-like areas which were removed in after initially being introduced in.

Command format

 * 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:.
 * Block limit changed from 4096 to 32768 blocks.
 * 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.
 * Similar to the  argument, but can be used to add (or remove) a certain number of blocks to the world border distance.

General

 * Block models
 * Instead of specifying uvs, the player can now choose textures to be projected onto the model.


 * Resources
 * Reworked 3D resources, adding the possibility of new blocks with multiple textures.

Trivia

 * 14w26a was previously removed from the launcher for some time, but was added back in September 2018.
