+`ruby-debug` is the same as `ruby-head` but with assertions enabled (`-DRUBY_DEBUG=1`).  
 On Windows, `mingw` and `mswin` are `ruby-head` builds using the MSYS2/MinGW and the MSVC toolchains respectively.
 
 Ruby 2.2 resolves to 2.2.6 on Windows (last build from RubyInstaller) and 2.2.10 otherwise.
