[Hawkular-dev] RfC: no longer support Ruby 2.0 in Ruby-Gem?

Hey, ManageIQ is using Ruby 2.2.4+ and Ruby 2.0 is pretty old now (Jruby 9.1.x is Ruby 2.3+), so I would like to no longer "support" Ruby 2.0. For the time being that only means that we do not test against 2.0 anymore in Travis. What do people think? What about 2.1 ? Heiko
