Good afternoon, we have received quite a few emails and posts asking when we plan to update Ruby to 1.9.3+. Our Ruby on Rails support is powered by Passenger. Currently you can only use one Ruby interpreter. That means that everyone gets the same version of Ruby. It’s not feasible to force all customers to update their applications to support 1.9.3 at this time.

That being said, Passenger 3.2 promises support for more than one version of Ruby at a time. It’s not released yet and it’s timeline isn’t 100% clear. A preview release was pushed out last week, we hope to begin testing it soon. When a stable version is released that we feel comfortable deploying you will begin seeing support for more than one version of Ruby.

You can read more about the upcoming Passenger release here and here.
