Phusion Passenger 3.0.19 released

By Hongli Lai on January 10th, 2013

Phusion Passenger is an Apache and Nginx module for deploying Ruby and Python web applications. It has a strong focus on ease of use, stability and performance. Phusion Passenger is built on top of tried-and-true, battle-hardened Unix technologies, yet at the same time introduces innovations not found in most traditional Unix servers. Since mid-2012, it aims to be the ultimate polyglot application server.

Recent changes

Phusion Passenger is under constant maintenance and development. New features will be introduced in Phusion Passenger 4. In the mean time, the Phusion Passenger 3 branch receives bug fixes only.

Phusion Passenger also has an Enterprise version which comes with a wide array of additional features. With the released of the open source Phusion Passenger 3.0.19, Phusion Passenger Enterprise has also been updated at the same time. By buying Phusion Passenger Enterprise you will directly sponsor the development of the open source version.
