The first Passenger 5 beta was released about 3 weeks ago. This major new version brought many changes, such as performance improvements, better tools for application-level visibility and a new HTTP JSON API for accessing Passenger’s internals.

Beta 1 was not considered production ready. In the past 3 weeks we’ve been working hard to fix bugs. The result is beta 2, which fixes 8 issues.

• Fixed handling of multiple Set-Cookie headers. Closes GH-1296.
• passenger-config system-metrics now works properly if the agent is installed in ~/.passenger. Closes GH-1304.
• Documentation enhancements by Igor Vuk. Closes GH-1318.
• Fixed some crasher bugs.
• [Standalone] User switching is now correctly disabled.
• [Standalone] Fixed the --thread-count parameter.
• [Apache] IPs set by mod_remoteip are now respected. Closes GH-1284.
• [Apache] Fixed support for gzipped chunked responses. Closes GH-1309.

Installing or upgrading

Here’s a quickstart:

gem install passenger --pre -v 5.0.0.beta2
cd /path-to-your-app
passenger start

Please note:

• 5.0.0 beta 2 is a beta release. There are still major bugs open and we do not recommend using it in production yet.
• There are no Homebrew or Debian packages for this release, because this release is still in beta!
• There is also a 5.0.0 beta 2 release of Phusion Passenger Enterprise available. Please refer to the Customer Area.
