20w46a is the second snapshot for Java Edition 1.17, released on November 11, 2020,[1] which adds powder snow among other changes.

Additions

Blocks

Powder snow
  • Entities that walk into it will sink in it.
  • Can be picked up and placed with a bucket.
  • Leather boots can be worn to prevent players 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.
