Changelog

Version 2.4.1:

  • Migrate to Mojang Mappings
  • Change some comments in the config file
  • Update to 1.21.11
    • Sky color is now data driven making sky color caching infeasible so it's been removed
    • Lightmap caching remains but no longer directly uses time as a factor, so lightmap_time_change_needed_for_update no longer has any effect
    • These changes don't apply to 1.21.10-
