Downloads for this preview can be found below, please note that these are not production ready! Use with caution and always make backups!

Opening as a draft now to keep track of TO-DOs 👀

API additions left:

  • supporting dyeable items - postponed
  • custom waypoints
  • custom entities???

Not api, not 26.2; still neat to have more testing:

  • hashed block ids - postponed
  • resolvable data components

26.2 changes:

  • ClientboundSetPlayerTeamPacket changes -> nullable team color!
  • Spectator action packet
  • new clientbound login packet field
  • geysers: particles / sounds / block entity
  • new entity attributes
  • sulfur cube
    • baby sulfur cube size
  • 26.30 based mappings + backwards compat
  • MushroomCow#mobInteract
  • beds are no longer block entities on Java, but are on Bedrock
  • gametests/component hashing
  • automate fabric.mod.json mc version via resource processing
  • Adventure 5.2.0: Needed for modded; needed to bump cloud properly

Mappings:

  • 26.30 -> 26.0 backward mappings
  • new sounds
  • new particles
