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

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 and currently doesn't work.^[2]

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.

/item

• Modifies the inventory of a block or entity.
  • This command has three forms:
    • /item <target> replace <item stack> [<count>] – same as old /replaceitem
    • /item <target> modify <modifier> – modifies item (without copying).
    • /item <target> copy <source> [<modifier>] – copies item for source to target(s), optionally applying modifier
  • Possible sources and targets: entity <selector> <slot> or block <x> <y> <z> <slot>
  • For example, /item block ~ ~ ~ container.0 copy entity @s enderchest.0 will copy first item from player's enderchest to first slot of container player is currently standing on.

Item modifiers

• Reuse functions syntax of a loot table to describe item modification in /item command.
• The function part of loot tables can now be defined as separate data pack resource in item_modifiers directory.
  • Such files can contain a single function (i.e single JSON object) or an array of functions.

Loot tables

• Rolls, set_damage, and possibly other parameters now require "type:uniform" (or other valid values for "type") when using min-max for numbers. set_count has had the same requirement for a few versions.
  • THESE CHANGES BREAK MOST EXISTING CUSTOM LOOT TABLES! MC-206118
• New condition: value_check
  • Checks range of value.
  • Parameters:
    • value – see "New value providers" section (currently combination of random generators and score)
    • range – min/max range
• New function: set_enchantments
  • Modifies enchantments on item.
  • Parameters:
    • enchantments – map of enchantment id to level value (can be score or random number)
    • add – if true, change will be relative to current level. If false, level will be replaced with current value (default behavior)
• New value providers: score
  • Returns scaled scoreboard value.
  • Parameters:
    • score – scoreboard name
    • target – same as target in score predicate
    • scale – scaling factor (float)

Tags

  • Contains snow and powder snow.
  • Blocks in this tag create snow stepping noises while the player walks in them.

Cauldrons

• Can now be filled with powder snow during snowfall.
• Using a bucket on a cauldron filled with powder snow empties the cauldron and creates a powder snow bucket.
• Can also be filled with powder snow by using a powder snow bucket on it.
