Ruby 1.9.2 Is Now The Default
June 08, 2011 by Adam Wiggins
Ruby 1.9.2 on Bamboo is now the default for new apps created on Heroku.
As we said back in April: Ruby 1.9.2 as the new gold standard for production Ruby apps. In 2011, we’ve seen more and more developers move to 1.9.2. It’s fast, stable, and sees excellent support throughout the community.
You can always list available stacks with the
heroku stack command; and if you want your new app on Ruby 1.8.7 you can run
heroku create --stack bamboo-ree-1.8.7 to explicitly ask for the older stack.
