+On Windows, `mingw` and `mswin` are `ruby-head` builds using the MSYS2/MinGW and the MSVC toolchains respectively.  
 Note that Ruby ≤ 2.3 and the OpenSSL version it needs (1.0.2) are both end-of-life,
 which means Ruby ≤ 2.3 is unmaintained and considered insecure.
 On Windows, Ruby 2.4 uses OpenSSL 1.0.2, which is no longer maintained.
