Changelog v0.11.0

v0.11.0

Released 13th July 2026.

This version introduces a major breaking change: the public blocking transaction API has been removed in favour of owner-safe scheduling APIs. See the v0.11.0 Migration Guide before upgrading. It also adds nether and End portals, shulker boxes, bamboo blocks, candles and a world-owned redstone engine.

Changes

player

• Implemented a client input lock system for selectively restricting player input
• Natural regeneration now matches vanilla behaviour

server

world/mcdb/leveldat

Breaking Changes

world

• Removed the public blocking transaction API (World.Exec and ExecFunc) in favour of owner-safe scheduling APIs:
  • World, EntityHandle and Player now expose Do() and DoAfter() for fire-and-forget scheduling
  • world.Call(), world.CallEntity(), world.CallRef() and player.Call() schedule work and await a result
  • Added world.EntityRef[T] and player.Ref for owner-safe entity handles, created via world.NewEntityRef() and player.NewRef()
  • Added Tx.Defer() and Tx.DeferErr() for scheduling follow-up work from within a transaction
  • Scheduling calls return a world.Task, exposing Wait(), Done(), Err(), Cancel() and OnDone()
  • Added world.RethrowPanic() and world.PanicError for surfacing panics raised inside scheduled tasks
  • See the v0.11.0 Migration Guide for a full before/after walkthrough of updating existing code
