[1.0.0] - 2026-06-04

Added

  • Initial release for Minecraft 1.20.1 / Forge 47+
  • Block tag #skylightlanterns:skylight_source — tag any lamp or sky block via datapack or KubeJS
  • Virtual skylight regions beneath tagged sources using a bounded flood-fill (radius, depth, and node cap limits)
  • Server-side SKY light boost so crops, saplings, and Dynamic Trees grow underground
  • Default virtual sky level 14 — enough for Dynamic Trees (≥12) without enabling canSeeSky() (requires 15)
  • MobMixin — undead do not sun-burn inside skylight regions when preventBurning is enabled
  • Optional hostile spawn blocking inside lit regions
  • Server config: config/skylightlanterns-server.toml (maxRadius, maxDepth, nodeCap, skyLevel, attenuateByDepth, preventBurning, blockHostileSpawns)
  • Performance safeguards: per-tick dirty-chunk budget, per-source node cap, no client light-engine rewrites

Technical

  • Mixins: LightEngine#getLightValue (sky engine only), LevelChunk#setBlockState, Mob#isSunBurnTick
  • Does not override canSeeSky() at default settings
