A small update porting all the way to 1.21.1!

Changes

Item Behaviour Components

• Renamed minecraft:record to minecraft:playable_song.
  • This makes it consistent with minecraft:playable and describes the behaviour better.
  • The term 'song' is used due to the new Jukebox songs that were added in 24w21a.
  • Its value is now an id pointing to a Jukebox song instead of containing the song data itself.
  • This value can be changed for individual item stacks in the minecraft:jukebox_song data component.

So if you had this:

{
  "minecraft:record": {
    "description_key": "item.minecraft.music_disc_cat.desc",
    "duration": 3700,
    "output_signal": 2,
    "sound_event": "minecraft:music_disc.cat"
  }
}

You must now use this instead:

{
  "minecraft:playable_song": "minecraft:cat"
}

With the following Jukebox song:

{
  "comparator_output": 2,
  "description": {
    "translate": "jukebox_song.minecraft.cat"
  },
  "length_in_seconds": 185.0,
  "sound_event": "minecraft:music_disc.cat"
}

Item Modifiers

• Reverted minecraft:set_potion to its vanilla state.
  • This has been replaced by the minecraft:set_random_potion item modifier.
• Added minecraft:set_random_potion.
  • This change is made for future compatibility with 26.1 snapshot 1.
  • Fields:
    • conditions: The conditions for the item modifier to apply.
    • options: An optional potion, list of potions or hash-prefixed potion tag. The possible potions to pick from. If not specified, will pick from every potion available.
