## [0.5.2] ### Fixed - Prevent initial chunk packets from waiting indefinitely with Fluidlogged API. Skip vanilla's redundant random player lighting repair request, which otherwise creates new pending samples before every send attempt. Block/fluid updates and the contextual-light gate used by Thaumcraft crystals remain active.

## [0.5.1] ### Fixed - Wait for pending contextual samples and nearby lighting before initial chunk transmission, including players joining an already-sent chunk. Preserve initial-packet, entity-tracking and Forge chunk-watch event ordering, and cancel deferred sends when players leave. - Rebuild Pulsar lighting after Chocolate Quest Repoured bulk dungeon writes, including the affected neighboring chunks. Delay relight refresh packets until neighboring work has finished. - Include requested absent sections in partial light refreshes even when their light is now default, so stale client light arrays are reset. - Invalidate older lighting caches (version 13); previously saved incorrect CQR lighting is recalculated when its chunks next load. ### Changed - Collect pending contextual light positions in primitive, atomically detached batches, avoiding boxed requests and per-tick set copying/removal. Iterate those batches without boxing and keep callbacks outside the producer monitor. **Full Changelog**: https://github.com/Sumire-Labs/Pulsar/compare/0.5.0...0.5.1

### Changed - Resolve sky source-face exclusions once per queue entry, retaining the encoded direction order and all sided/contextual/fluid behavior. - Specialize block propagation through verified plain air, avoiding generic absorption, emission and sided-flag work after the existing level guards. - Keep a just-active shared worker available for a bounded 5 microseconds for rapid follow-up work, without holding dispatcher or queue monitors. - Claim paired same-chunk light work after the first lane finishes, so later notifications can join the queued partner batch while the existing 5x5 reservation remains held. - Introduce managed Pulsar Config Version 2. Missing or mismatched versions regenerate the whole config with current defaults before settings are loaded; matching versions retain custom settings. - Default server lighting configs to automatic shared-pool sizing (-1), including migration from older configs, and document restart requirements. - Expose dedicated-worker batch time, unload lighting wait time, idle engine cache size and statistics log interval with bounded values and config comments. - Optimize light propagation, source scanning, skylight updates and chunk-map lookups to reduce allocation and redundant work. - Track contextual TileEntity light changes each tick, keeping Mod callbacks on the world thread. - Coalesce client render updates (`features.coalesceClientRenderUpdates`) and alternate sky/block tasks within a shared soft budget (`features.clientLightBudgetMs`, default 2 ms). - Add a configurable shared server lighting pool (`features.experimentalServerLightThreads`, default `-1` selects CPU/3 workers), with nearby-task exclusion and paired sky/block scheduling. - Add opt-in shared-pool range relighting (`experimentalRangeRelight`, default off), with world-wide job exclusion and generation-safe publication. - Update lighting statistics once per world tick, with dimension IDs and more detailed task, client and contextual-sampling timings. - Share a 10 ms lighting wait allowance across chunk unloads per world tick; unfinished lighting is invalidated for the next load. ### Fixed - Fix stale or incorrect skylight after dense edits and changes to opaque or shaped blocks, including across chunk boundaries. - Preserve block light in absent sections when sending full or partial chunks. - Recheck light-relevant block changes and include the center chunk's Fluidlogged capability during initial lighting. - Prevent light-array publication after chunk unload and exclude unfinished lighting from cache saves. Lighting cache version is now 12; older caches are relit when their chunks next load. ### Removed - Remove the Pulsar Colored Lighting Addon backend API and integration hooks. Pulsar now uses its built-in scalar engines. **Full Changelog**: https://github.com/Sumire-Labs/Pulsar/compare/0.4.0...0.5.0

## Fixed - Fixed a bug where multi-blocks were duplicated within the world **Full Changelog**: https://github.com/Sumire-Labs/Pulsar/compare/0.3.1...0.3.2

## [0.3.1] ### Changed - Added Natural Lighting for Thaumcraft 6 Crystal ### Known Issues - Immersive Engineering multiblocks multiply #14 This will be fixed in version 0.3.2 or 0.4.0 (the next release). ### Note I'll be busy for a while, so updates may be on hold for about 1 to 2 weeks. **Full Changelog**: https://github.com/Sumire-Labs/Pulsar/compare/0.3.0...0.3.1

## [0.3.0] ### Changed - Reduced unnecessary lighting work by queuing light checks only for the requested light type (sky light or block light). - Kept batches of updates within a single vertical block column on the incremental skylight update path, avoiding unnecessary full skylight rebuilds. ### Fixed - Fixed water and other liquids losing their configured light attenuation through automatic face-transparency handling. Water now uses its vanilla attenuation of 3 instead of 1. - Fixed weakened skylight propagating downward without further attenuation, including through empty sections. - Fixed swapped block-light and sky-light channels in smooth painting rendering, which could make paintings appear dark near torches at night. The correction applies to both vanilla paintings and JSON Paintings ([#12](https://github.com/Sumire-Labs/Pulsar/issues/12)).
