Is Rails version 3.1.1 compatible with Ruby version 2.3?

I am in a situation where I need to update several API-connected gems that are no longer supported by my current version of Ruby. (1.9.3) The Rails release notes for Rails version 3.1.1 state that Rails 3.1 requires Ruby 1.8.7 or higher but it's hard to tell if that includes versions of Ruby which might have been updated more recently than the release notes.

Am I good to update to 2.3 on my Rails 3.1.1 app?
