@@ -18,7 +18,6 @@ Performance optimizations across rendering, audio, and entity systems!
 - Renderer: column-level frustum culling and compact visible-chunk lists skip thousands of empty iterations per frame; lightweight second-pass render path avoids redundant checks
 - Sound engine: filesystem probe results are now cached, eliminating repeated file-existence checks every time a sound plays; sounds are pre-decoded for smoother playback
 - Entity movement: reduced `shared_from_this()` overhead by caching the shared pointer; `dynamic_pointer_cast` replaced with a raw pointer cast guarded by `instanceof`
-- Lighting: `checkLight()` is now skipped when tile light properties haven't changed, avoiding unnecessary light recalculations
 - Chunk updates: early-out for non-dirty chunks in the update loop; scaled recheck period at high render distances
 - Threading: entity query locking consolidated at the `Level` layer on all platforms for consistent thread safety
 - Block breaking: server now skips redundant tile-update packets when a block is successfully destroyed
