Fixed bugs in 25w02a

It's the first snapshot Wednesday of 2025, and we have some fun new features to kick off the new year. This snapshot adds new ambient features to the game, including wildflowers, leaf litter, and falling leaves. Pigs are getting two new variants: you may venture into the colder biomes to find the cold pig, or head for sunnier spots to meet its counterpart – the warm pig! Lodestones are also becoming easier to craft, making them more accessible in the early game. Now you'll only need an iron ingot with your chiseled stone bricks.

Technical Changes

  • The Data Pack version is now 62
  • The Resource Pack version is now 47

Data Pack Version 62

  • Changes to commands
  • Updated data format of Text Components
  • structure_block in the load mode has now a new option: Strict Placement
    • If set to false, the blocks in the placed structure will not trigger block updates, block entity side effects, or shape updates
  • The Owner field of tamed animals is no longer restricted to referencing Players
  • Updated data format of equipment drop chances in entity data
  • Added data-driven registry for pig variants
  • Added pig entity sub-predicate for matching pig variants

Commands

  • Text Components in commands such as /tellraw or /title are now specified with SNBT instead of JSON
  • Text Style in the /scoreboard command when specifying the styled number format is also now specified with SNBT instead of JSON
  • The behavior of setblock and fill commands have changed in how they handle block entity data:
    • If the block entity data is not specified, and the existing block has data, the block entity data will be preserved
    • If the block entity data is specified, the block entity data will be set to the specified value
    • To clear the block entity data explicitly, you must now specify the block entity data as {}
    • The operation is now successful if either the block state changed or the block entity data changed
  • fill, clone, setblock and place template accept a new option: strict
    • If specified, the command will place blocks as-is without triggering block updates and shape updates
  • The replace option in the fill command is no longer terminal, and can be followed with additional options
  • New syntax for commands to use the new strict option, and more flexible use of replace:
    • fill <from> <to> <block> keep
    • fill <from> <to> <block> [replace <filter>]? [strict|destroy|hollow|outline]?
    • clone [from <sourceDimension>]? <begin> <end> [to <targetDimension>]? <destination> [strict]? [[replace|masked|filtered <filter>] [force|move|normal]?]?
    • setblock <pos> <block> [destroy|keep|replace|strict]?
    • place template <template> [<pos> [<rotation> [<mirror> [<integrity> [<seed> [strict]?]?]?]?]?]?

Text Component Data Format

  • Text Components are no longer stored as JSON wrapped by a string
  • The format itself is the same as before, but inlined directly into the outer structure
  • For example, the item component minecraft:custom_name="{\"text\":\"Renamed item\"}" will become minecraft:custom_name={text:'Renamed item'}
  • This includes Text Components passed as arguments to commands such as /tellraw or /title
    • For example, /tellraw @s "\"text\":\"Hello world\"" may become /tellraw @s {text:'Hello world'}
  • Note: in the case where Text Components are embedded in NBT, no distinction exists between boolean and integer types
    • To pass boolean arguments to translations, you must use the string form
  • For Text Components with the nbt type and interpret set to true, Text Components will be parsed from the given NBT directly rather than converting to string and parsing as JSON
  • The format of hover and click events has been updated

Hover Events

  • The hoverEvent field has been renamed to hover_event
  • The legacy value field (which was parsed from a rendered text component) is no longer supported

    • The contents field has been inlined
    • e.g. {action:'show_item',contents:{id:'minecraft:stick',count:2}} becomes {action:'show_item',id:'minecraft:stick',count:2}
    • If contents was specified only as an item id, it is replaced with the full format and inlined
    • e.g. {action:'show_item',contents:'minecraft:stick'} becomes {action:'show_item',id:'minecraft:stick'}
  • For the show_entity action:
    • The contents field has been inlined
    • The id field has been renamed to uuid
    • The type field has been renamed to id
    • e.g. {action:'show_entity',contents:{id:[I;0,0,0,0],type:'minecraft:pig'}} becomes {action:'show_entity',uuid:[I;0,0,0,0],id:'minecraft:pig'}

Click Events

  • The clickEvent field has been renamed to click_event
  • For the open_url action:
    • The value field has been renamed to url
    • The click event will no longer parse if not a valid URI with either https:// or http:// schemes, instead of simply not working
    • e.g. {action:'open_url',value:'https://minecraft.net'} becomes {action:'open_url',url:'https://minecraft.net'}
  • For the run_command action:
    • The value field has been renamed to command
    • The click event will no longer parse if the command contains disallowed characters, instead of simply not working
    • It is no longer required that the specified command field has a / prefix
    • e.g. {action:'run_command',value:'/say Hi'} becomes {action:'run_command',command:'/say Hi'}
  • For the suggest_command action:
    • The value field has been renamed to command
    • The click event will no longer parse if the command contains disallowed characters, instead of simply not working

  • For the change_page action:
    • The value field has been renamed to page
    • The page value now requires a positive integer instead of a string
    • e.g. {action:'change_page',value:'1'} becomes {action:'change_page',page:1}
