FYI: I'm contacting the repo owner to see if I can help maintain.

[devnexen]

ah right I did not see your ticket sorry.

[JohnTitor]

Well, I didn't mention it on the issue so it's not your fault :)

So, the initial thought on the original PR was that the values on mach.h were often updated/deprecated and versioning here didn't fit it. Are they still updated often?

[devnexen]

Not necessarily very often but still occur yes.
