I'd like to know whether it is yet safe and production-ready to upgrade to Ruby 1.9. It seems to come with some benefits.
The gems I'm using include RSpec, RSpec-Rails, Cucumber, Webrat, Capistrano, Nokogiri, and MySQL.
On my server, I deploy on Passenger.
One thing I'm curious about is Ruby Enterprise Edition. I already run this on my server, but I don't think they have a 1.9 version yet, do they? So is it better to stay with this and Ruby 1.8.6, or to upgrade to Ruby 1.9?
Thanks in advance.
