What's new

1.12.2

  • Baubles is bridged to Curios (with Curios installed): bauble items become curios, BaublesApi and the Baubles capability are views over the Curios slots; Botania and other Baubles mods load without the legacy Baubles jar.
  • Container GUIs opened from blocks work again (Mekanism machines and others).
  • Mod armor can be worn in every slot, and armor and weapon stats apply.
  • Immersive Engineering, Tinkers' Construct, Quark, Botania and CodeChickenLib initialise on the client.
  • Custom registries are filled in Forge's order (sorted by name, object holders refilled after each).
  • Fixed: a stack overflow when Quark's greener grass wrapped the vanilla grass colour; Scape and Run: Parasites' toxic cloud crashing.
  • Many more legacy APIs implemented (entities, rendering, world generation, GUIs, Forge events).

1.7.10 and 1.12.2

  • Tinkers' custom heart rows are skipped so the vanilla hearts show.
  • World.loadedEntityList is built once per tick (low TPS with Portal Gun).
