Java Edition 20w46a

20w46a is the second snapshot for Java Edition 1.17, released on November 11, 2020, which adds powder snow among other changes.

Blocks

 * Powder snow
 * Entities that walk over it sink into it.
 * Can be picked up and placed with a bucket.
 * Leather boots can be worn to prevent entities from sinking into powder snow blocks.
 * Players can still crouch to descend with leather boots. Wearing leather boots also allows powder snow to be "climbed", like water or scaffolding.
 * Entities in powder snow slowly freeze.
 * Once frozen, damage is slowly dealt to the entity.
 * Wearing leather armor is intended to slow the freeze effect, and a full set of leather armor is intended to stop the freeze effect. However, this feature was not implemented properly.

Items

 * Powder snow bucket
 * Using a bucket on powder snow creates a powder snow bucket.
 * Powder snow buckets can be used to place powder snow.
 * Powder snow buckets can also be filled from cauldrons filled with powder snow.

Command format

 * Modifies the inventory of a block or entity.
 * This command has three forms:
 * – same as old
 * – modifies item (without copying).
 * – modifies item (without copying).
