What are different possible values for POSIX::uname() release number on Windows?

Question

I want to determine which version of Windows I'm on using POSIX::uname. I know it returns 6.2 on Windows 2012. I found a table of these values, Windows version and corresponding release number but I can't find it anymore. I've been searching the documentation, and I'm not able to run uname on every operating system to test it right now. Does anyone have a link or know which numbers correspond to which version of Windows?

On Windows, POSIX::uname obtains its information from GetVersionEx whose parameter's documentation contains a table.

The Win32 module provides more user-friendly calls.
