Additions
World generation
- New generated structure.
- Located in swamp biomes.
- Spawn witches.
General
NBT format
- Custom items can now be named using NBT data (intended for custom map makers).
- Using the NBT, it is possible to add custom [String] Name to items, as well as a [NBT List / JSON Array] Lore list for that item.
- Added preset "Redstone Ready" with 52 layers of sandstone, 3 layers of stone and 1 layer of bedrock.
Changes
Blocks
- Texture has been altered.
- Beam texture has also been changed.
- Spreading has been nerfed to prevent infinitely spreading fires.
Items
- Can now be used in superflat worlds, if the stronghold generation is enabled.
Mobs
- Now spawn in swamp biomes at low light level.
Gameplay
- Better management.
- The pick block action now works on blocks that are represented as items in the inventory (e.g.: redstone repeater, redstone dust, and tripwire).
- Pressing the 1-9 hotkeys while hovering over an item puts that item into the corresponding hotbar slot.
- If there is already an item in the assigned hotbar slot, the hotbar item and the selected item swap position.
- When in Creative inventory, a full stack of that item is transferred to that hotbar slot.
- In Creative mode, players can now shift-click items between the hotbar and the Survival inventory.
- The left-click action no longer opens doors, pulls levers, pushes buttons or opens trapdoors.
- When in Creative mode, pick block on an item picks up a stack of that item.
General
- Configuration now allows the player to generate trees, strongholds etc.
- Now pumpkins, short grass, ferns, flowers, trees, mineshafts, dungeons, strongholds, lakes, desert wells, ravines and ores spawn on superflat maps.
Fixes
13 bugs fixed
- Fixed the wither's starting explosion not being disabled by the
mobGriefinggamerule[2] - Fixed a few crash bugs related to world generation, map item expansion, and other things.
- Reverted lighting changes that had been introduced in snapshot 12w39a. This change corrected such bugs as:
- The Nether being extremely CPU intensive.
- Map generation taking extremely long.
- Fixed mob AI considering cobblestone walls as blocks of normal height.
- Fixed a few texture oddities with the witch.
- Fixed entities in water producing glitchy water sound.
- Gaining multiple levels at a time no longer plays the leveling up sound over itself as many times as leveled.
- Fixed the "A 64 bit Java installation is recommended for 'Far' render distance (you have 32 bit)" message being covered by the bottom 2 buttons.
- Fixed pets teleporting around randomly.[3]
- Fixed being unable to place paintings larger than 1x2 and them popping off if they have been placed before.
- Fixed destroying blocks under the player with efficiency-enchanted gear.
- Fixed potion spawners crashing the game.[4]
