Since sp614x cannot develop or maintain these releases, we want to help prevent bug reports as much as possible. Because of this, I have put in a lot of places that it is not official. Like this download page and the installer. I also changed "HD_U" to "HD_K".
The K in "HD_K" stands for Kai, which is my cat's name.

Q:
A: I decompile OptiFine's source code and port OptiFine to some of the latest snapshots. I use an entirely different code-base than sp614x, and I cut a few corners which allows me to update OptiFine quicker. This is probably the best way to properly port OF to a new snapshot release every week.
Q:
A: It is possible for me to port to the latest major release, though, I have decided to *not* do that. I am not wanting to take control of OptiFine, so, that is sp614x's job, not mine.
Q:
A: It supports both NeoForge and Forge. Though, due to some limitations, it requires to download a seperate jar file. It will end with "-neoforge.jar" (Only supported for versions 1.20.2 and up!)
NeoForge and Forge do not release versions for snapshots, so it only works on full releases. But, I have opted into still releasing both builds, just in case.
