Phusion Passenger 4.0.1 released

[Hongli Lai]

After a period of being in beta, we’re proud to announce the first
stable release of the Phusion Passenger 4 series. The 4.x series is a
huge improvement over the 3.x series: during the development of 4.0,
we’ve introduced a myriad of changes which we’ve covered in past beta
preview articles:

* Support for multiple Ruby versions, support for Python WSGI,
multithreading, evented core similar to Nginx and Node.js, real-time
response buffering, improved zero-copy architecture, better error
diagnostics. (http://phusion.us5.list-manage.com/track/click?u=9798cf0716b767b7c062d0f6f&id=624a9cffaf&e=58db089fc0)
* JRuby and Rubinius support.

* Out-of-Band Work.

* Support for the Rack socket hijacking API.

* Improved stability and test suite

.

The beta period took a while because we wanted to ensure that the
first stable release is indeed rock solid. People tend to say that one
should skip “x.0.0″ releases and wait until “x.0.1″ for the first bug
fixes. But we’re confident enough about the stability of the 4.x
series that we gave this first release the version number 4.0.1.


** Changes in 4.0.1
------------------------------------------------------------

Compared to 4.0.0 RC 6, the following changes have been introduced:
* Fixed a crasher bug in the Deployment Error Resistance feature.
* Fixed a bug in PassengerDefaultUser and PassengerDefaultGroup.
* Fixed a bug which could cause application processes to exit before
they’ve finished their request.
* Fixed some small file descriptor leaks.
* Bumped the preferred Nginx version to 1.4.0.
* Editing the Phusion Passenger Standalone Nginx config template is no
longer discouraged.
* Improved documentation.
