OpenProject 3.0 has been released with major improvements compared to the prior version 2.4.
You can easily create your own OpenProject sandbox to try out OpenProject 3.0.
We postponed releasing OpenProject 3.0.0 by one week to March 7th 2014.
We have created a project on Crowdin to translate the UI of OpenProject to further languages: https://crowdin.net/project/openproject. Please join!
In our effort to improve performance we switched OpenProject 3.0 to run on Ruby 2.1.
