From 4e29ca0c4093133838eda852879b23ed4fad56b5 Mon Sep 17 00:00:00 2001

Subject: Add :ssl_min_version and :ssl_max_version options

Replace :ssl_version option with these two new options. These provide
access to OpenSSL::SSL::SSLContext#{min,max}_version=, which is the
recommended way to specify SSL/TLS protocol versions.
