I’m already sold on Passenger and talked it up a bit at RailsConf. Still the list of features coming for version 2 are impressive and should win over some holdouts still using mongrel+nginx and similar setups. Passenger 2.0 will have Rack support, reduced memory usage, fair load balancing, upload buffering, as well as performance and stability improvements. Release Candidate 1 is available now for testing and I may test though I may just wait for 2.0 to be released and upgrade my systems then. More information can be found in the Passenger RC1 Annoucement.

A changelog for the recent versions of Passenger (1.0.3-1.0.5) was recently posted. I decided to do a quick upgrade to 1.0.5 following the steps I’ve used previously. Those steps are documented as follows.
