Additions

Created when using "Frost Walker" enchantment.
Cannot be obtained in inventory, neither with Silk Touch, pick block nor with commands. (Can only be placed using Template:Cmd, Template:Cmd etc.)
Despawns after a few seconds.
- Despawning takes place in four breaking stages (blockstates: age:0, age:1, age:2, age:3). Still decays with randomTickSpeed set to 0, but a higher number makes it decay faster.
- Despawns faster with a higher light level (doesn't despawn at night).

Minecraft:Brewing stands
- Fuel (byte): Stores how much fuel is remaining in a brewing stand.
  - e.g. /setblock ~ ~1 ~ minecraft:brewing_stand 0 replace {Fuel:127b}.

"Treasure" enchantments.
- Can only be obtained from Minecraft:chest loot, Minecraft:fishing, or Minecraft:trading for enchanted books.
New treasure enchantment: Minecraft:Frost Walker.
- Turns water into Minecraft:frosted ice.
- 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.
- Works while riding mobs.
- Doesn't turn water into frosted ice if an entity is in that spot.
- Works as long as the Minecraft:player is within one block above a solid block.
- Flowing water also turns into frosted ice, making one bucket of water enough to make an infinite water source.
- Cannot be combined with Minecraft:Depth Strider enchantment.
New treasure enchantment: Minecraft:Mending.
- Any experience collected while holding the item repairs it instead of going to the experience bar.
  - Mainhand, offhand, and armor slots all count as held.
  - If multiple held items have the enchantment, one is chosen at random for each XP orb collected.
  - Repairs at a rate of 2 durability per XP.
  - If the amount of repair needed is less than the value of the XP orb, the extra XP goes to the experience bar.
  - Minecraft:Shields cannot be enchanted with Mending using Template:Command or an anvil in Survival.
    - Mending enchantment does affect the shield when using anvil in Creative or NBT commands.

Added the following splashes:
- "Falling with style!"
- "There's no stopping the Trollmaso"
- "Throw yourself at the ground and miss"

Requires Minecraft:blaze powder to be able to use.
- One piece of blaze powder allows for 30 ingredients to be brewed in the brewing stand (tag: Fuel:30b).
  - To be exact, it removes 1 from fuel (1 blaze powder = 30 fuel) every time the Minecraft:player puts an ingredient in (if the player takes it out and puts it back in, it takes another fuel).
- Can be automated by putting a hopper feeding in the side of the block like water bottles.

Nerfed - the player is no longer able to go higher than where they started.
New sneaking animation.
The player can now fit through one block high gaps while gliding.
Horizontal collisions now deal damage, new death message: "Player experienced kinetic energy".

Now slightly faster than sprinting.
- This makes them similar in speed to the old boats, though with less momentum.
Players can now Template:Control items and Template:Control immediately after they stop rowing.
All types of boats are now craftable, except for dark oak boats.<ref>Template:Bug</ref>

Renaming an item does not increase the repair cost for a future repair/rename any more.

Enchantments with maximum level I no longer display the level, e.g. "Infinity" rather than "Infinity I".
When multiple pieces of Thorns armor are worn, one is now chosen at random instead of always using the "bottommost" piece.

15w42a was previously removed from the Minecraft:launcher for some time, but was added back in September 2018.
