Hi,

The Ruby website says "Support for Ruby 1.9.3 has ended"

https://www.ruby-lang.org/en/news/2015/02/23/support-for-ruby-1-9-3-has-ended/

But sup github page still recommends 1.9.3.

https://github.com/sup-heliotrope/sup/wiki/Installation%3A-General-Process

I have tried ruby 2.2.1. But sup can not be correctly installed.

Could anybody let me know which version of Ruby is currently recommend to 
use with sup?

Regards,
Peng
