[1.0.1] - 2026-07-10

Changed

  • Block changes that do not affect opacity or light emission no longer trigger lighting calculations.
  • Optimized region indexing, queue processing, and light section publishing.

Fixed

  • Prevented stale asynchronous lighting results from being published after the source chunk has been unloaded or replaced.
  • Fixed batched block light updates failing to propagate beyond immediately adjacent blocks.
  • The fast batch path now correctly falls back to a full recalculation when light emission decreases or block opacity changes.

This release should give a bit more smooth and better experience in large modpack environments where a lot of stuff with light may do weird stuff. Report any issues on GitHub.
