This has already been released to users and now it will require us to diverge from upstream as we have to bump the version again for the next release. I think that was probably why we used arbitrary version tags here

Hello,
Okay, that was my mistake. I apologize for that. As for the version number, I wrote in the PR that, in my opinion, it reflects the actual original HyperHDR version, so there won't be any further confusion or questions.
According to https://github.com/awawa-dev/HyperHDR/releases/tag/v22.0.0.0beta2, v22.0.0.0beta2 has been released.
I’ll wait for approval before merging it in the future. You can change anything. Please make the necessary corrections.
