Additions

Blocks

Emerald ore

• Drops 1 emerald when mined.
• Generates in blobs of up to 10 blocks.

Ender chest

• Crafted with 8 obsidian and 1 eye of ender.
• All ender chests in a world have the same contents, if those contents change it affects the contents of all other ender chests.
• On multiplayer, the ender chest's contents are the same for all players on a server.

Sandstone stairs

• Have the same function and recipe as other stairs, but made of sandstone.

Items

Emerald

• Dropped when mining an emerald ore block.
• Used in villager trading.

Enchanted golden apple

• A second type of golden apple made with blocks of gold.
• After being consumed, the player receives 30 seconds of Regeneration IV, plus Resistance and Fire Resistance for 5 minutes.

World generation

Desert temples

• New generated structure in desert biomes that resemble pyramids.
• Have a TNT trap and loot chests inside.

Desert villages

• Villages that generate in desert biomes now are made of sandstone rather than wood and cobblestone.

Gameplay

Trading

• Villagers buy or sell the player emeralds in exchange for certain items.
• Trade with villagers by right-clicking on them, opening up a GUI with one buying slot and one selling slot.

Command format

Commands

• /seed
  • Displays the current world seed.

Changes

Blocks

Dispensers

• Eject water and lava source blocks from buckets.
• Also take water and lava source blocks if there is an empty bucket inside.

Gravel

• Changed texture.

Locked chest

• Removed old chest texture, causing locked chests to appear as the purple default block.

Items

Buckets

• Now stackable to 16.

Mobs

Passive mobs

• Can be easily pushed around by simply walking, most likely intended to help the player navigate through animal farms more easily.

Non-mob entities

Boats

• Now pass through lily pads without breaking the boat; the lily pad drops as an item instead.

Minecarts

• While sitting inside of a minecart, pushing the directional keys makes it move the direction player is pressing. This only works while the minecart is sitting on rails.

Gameplay

Creative

• Added snow to the Creative inventory.

Singleplayer

• Removed server jar dependency in singleplayer.

Sky

• Stars are more realistic.
  • They are now slightly smaller and slightly brighter.

General

Options

• Improved options menu.

Debug screen

• The F3 menu no longer has the frame time graph.

Trivia

• In this version, when loading a singleplayer world, one needs to put minecraft.zip/server/minecraft_server.jar into .minecraft/server manually to continue loading.
