Updated to 1.21.4
Fixed lighting issues.
Special thanks to DarkChroma admin of CatCraft for the support.

CHANGES:

• Now it uses Java 21.
• Every new version will be compiled against a paper version; if you are seeking retro-compatibility, use an older version,
• If the server is running in an incompatible version, it will disable the plugin and log this info.
• Sometimes the "prevent-xray" setting may break the extended view distance. If you experience issues, disable the "prevent-xray" from the config.

Sorry for the delay from the bottom of my heart, I've received a promotion on my current job and my college this semester is 9 disciplines....

This release is about:

• a hotfix to the client disconnect on version 1.20.4, and a warning to not use that version. (see below)
• fixes the lightning errors on 1.21

as usual, please use a paper fork.

Thanks VS.GNOME for reporting.
Let me know if the same occurs on the 1.21...

Added 1.21 support and fixed the known issue of some areas of the extended view being darken.
Again, compiled with paper-nms (mojang mappings) it may or may not work on spigot.

If you encounter issues, please report them on Github.
It may or may not work on spigot, I've compiled for paper.

Added support to paper builds of 1.20.6, spigot not tested yet.
**Known Issue**: The extended chunk light will be the same as when the chunk was first generated until updated, for example, if the chunk were generated at night, it'll be rendered, but darken.

Please do not post your bugs in the review section, I'm not receiving anything to maintain this plugin, so add your issues to the GitHub issues section.

Now it supports 1.19.4, 1.20, 1.20.2 and 1.20.4 (1.20.3 might work, but it's recommended to use 1.20.4)

Some changes happen on the packets of the NMS internals.
Now it supports 1.19.4 ~ 1.20.2

Fixed the bug where the plugin sends all the chunks at once, even the light updates. (that was only on unoptimized clients). Now, the chunks may take a while (actually the normal game tick rate) to load without crashing.

Tweaking the code implementation a little.
Screenshot of it working on version 1.20.1

server render distance: 1
player render distance: 32

Working as expected!

Thanks, SinistersGrin.
