Heroku is fully behind Ruby 1.9.2 as the new gold standard for production Ruby apps. Over the past few months, we’ve seen more and more developers move to the Bamboo 1.9.2 stack. It’s fast, stable, and increasingly sees excellent support throughout the community.
In February, we said that we’d be reviewing the state of 1.9.2 support with the eventual goal of switching the default for new Ruby apps on Heroku from 1.8.7 to 1.9.2. Today, we’re announcing the date of that switchover.
As of June 1st, 2011, all new Ruby applications on Heroku will be run on Ruby 1.9.2 by default. (Existing applications won’t be affected, and you can always create a new application on 1.8.7 by running heroku create --stack bamboo-ree-1.8.7.)
But there’s no need to wait till June – get started with a Ruby 1.9.2 app on Heroku today with the following command:
$ heroku create --stack bamboo-mri-1.9.2
