Java Edition 15w42a

15w42a, the thirty-third snapshot released for 1.9, introduces two new enchantments and a new block, plus improvements to boats.

Additions

 * Enchanting
 * Frost Walker
 * Can only be found.
 * Creates frost blocks when walking over water.
 * Different tiers:
 * Level I creates a circle of frosted ice around the player with a radius of 2 blocks.
 * Each additional level adds 1 to that radius.
 * There are 2 tiers
 * You need to be on ground to initiate the freezing effect, while submerged in water or while in air, water does not turn into frosted ice.
 * Does not generate frosted ice if there is an entity submerged with that water block, such as a boat or a mob.
 * Flowing water will also turn into frosted ice, making one bucket of water enough to make an infinite water source. (You only need to walk on the same level as the flowing water to turn it into frosted ice and wait until it unfreezes.)
 * Cannot be combined with Depth Strider enchantment.


 * Mending
 * Can only be found.
 * Allows items (armor/tools etc.) to stay durable, at a cost.
 * Any experience collected while holding the item repairs it instead of going to the experience bar.
 * If the tool you are holding cannot be repaired, it will go to the experience bar instead.
 * Repairs at a rate of 2 durability per XPOrb with a  tag. (found out using NBT tags)
 * Multiple items can be repaired at the same time, items held in offhand, mainhand and armor slots will all be repaired.
 * Elytra wings can be repaired infinitely this way.
 * Shields cannot be enchanted with mending using /enchant command or a survival anvil.
 * Mending enchantment does affect the shield when using creative anvil or NBT commands.


 * Blocks
 * Frosted Ice
 * Created when using "Frost Walker" enchantment.
 * Cannot be obtained in inventory, not with silk touch, not with commands. (Can only be placed using /setblock)
 * Despawn after a few seconds.
 * Despawning takes place in four breaking stages (blockstates: ). Still decay with randomTickSpeed set to 0, but a higher number will make them decay faster.

Changes

 * Anvil repairing
 * Renaming an item does not increase the RepairCost for a future repair/rename anymore.


 * Boats
 * Improved speed and handling
 * You can now craft all types of boats.


 * Brewing Stand
 * Requires blaze powder to be able to use
 * One piece of blaze powder allows for 30 ingredients to be brewed in the brewing stand (tag: ).
 * To be exact, it removes 1 from fuel (1 blaze powder = 30 fuel) everytime you put an ingredient in. (If you take it out and put it back in, it takes another fuel)
 * Can be automated by putting a hopper feeding in the side of the block like water bottles


 * Elytra
 * Death message now says that you've experienced too much kinetic energy.
