Ruby 1.9 is Production Ready - The Fastest Ruby Ever

Exciting news people:

Years of hard work reached a crescendo today as Yuki Sonoda announced the release of Ruby 1.9.1, the first stable release of the Ruby 1.9 series of MRI. In effect, 1.9.1 replaces 1.8.7 as the latest stable release of "Matz's" Ruby interpreter although (as we'll cover below) it's not entirely that simple.

We'll be doing a roundup of Ruby 1.9 related links and resources soon here on Ruby Inside, but if you want to get up to speed with what Ruby 1.9 is all about right now, I'd recommend checking out the Migrating to Ruby 1.9 presentation by Bruce Williams, Ruby 1.9: What to Expect by Sam Ruby, and James Edward Gray's Getting Code Ready for Ruby 1.9. Mauricio Fernandez's Changes in Ruby 1.9 is a more exhaustive list and is still pretty good although it was last updated over a year ago.
