CHANGES

TECHNICAL CHANGES

• The Data Pack version is now 19
• A few minor changes to chat component serialization

CHAT COMPONENTS

SERIALIZATION

• Plain-text chat components (text, no sibilings, no stylings) are now always serialized as string instead of {"text': "blah"}
• Chat components now serialize to NBT when sent over network
• Chat components now have an optional type value (allowed values: text, translatable, score, nbt, keybind) to speed up parsing and improve error checking
• id field in show_entity hoverEvent style now also accepts UUID as an array of 4 ints
• Numeric and boolean arguments for translate component are no longer converted to string
• The following JSON component representations are no longer accepted:
  • null
  • []
• Errors in following style fields are no longer silently ignored:
  • color
  • clickEvent
  • hoverEvent
  • hoverEvent[action=show_entity].contents.name
  • hoverEvent[action=show_item].contents.tag

DATA PACK VERSION 19
