What it does

Improves the performance of light updates in Minecraft the same way Starlight did.

Why should it be in the modpack

• Contains all the performance improvements from Starlight with additional bug fixes.
• Optionally allows for parallel light updates, bringing significant performance improvement in high-speed world generation and heavy light updates scenarios.

Why shouldn't it be in the modpack

Untested, may be unstable, may not provide any noticeable benefit to the client / the integrated server running in singleplayer on the client.

Additional details

No response

This mod is meant for large servers, where generating many chunks at the same time is common and the CPU has many cores.
I don't think it has any impact on the client

Starlight (the original mod this one forked) was discontinued upon the release of Minecraft 1.20 because Mojang already implemented these improvements, hence this does not make sense to re-add.

I think it would still have benefits on the integrated server

The base Starlight is still 100% faster than vanilla, allowing the chunk system to scale beyond 24 threads.
The performance of vanilla lighting engine is still a bottleneck for high-performance chunk generation.
