Version 6.0.3 of the Passenger application server has been released. As you may have noted this release took much longer than usual and delayed support for Ubuntu 19.04, we have our CI system back up and running, and can cut releases again.

Passenger 6, introduced Generic Language Support, or: the ability to support any and all arbitrary apps.

Specify Spawn Dir Location

Passenger 6.0.3 adds an option to specify the app spawn directory during startup, which is specifically useful for CageFS users. Contributed by @plmnikulin.

- Apache: `PassengerSpawnDir`
- Nginx: `passenger_spawn_dir`

This addition closes issue GH-2145.

Updates & improvements

  • [Nginx] The preferred PCRE version is now 8.43 (previously 8.42).

  • Adds Ubuntu 19.04 "Disco" packages, and removes Ubuntu 18.10 "Cosmic" and Ubuntu 14.04 "Trusty" packages.

  • Changes minimum supported macOS version to 10.12 Sierra.

  • Improves container detection and fixes a compilation warning in GCC 8+. Closes GH-2186.

  • Allowed externally specifying an app instance to send a request to. Contributed by Mark R. James (@mrj).

  • Fixed an incompatibility with sending requests to specific app instances, when using the rails web-console gem. Contributed by Mark R. James (@mrj).

  • Fixed a regression (introduced in 5.1.9) where some hooks were not called. Closes GH-2103. Contributed by Mark R. James (@mrj).

  • Fixes compilation with clang 8 (latest macOS update) by updating vendored boost library from 1.67 to 1.69.

What's next?

You may have noticed we didn't add packages for Debian Buster in this release. We have to make some changes to our buildbox first and didn't want to further delay this release until that was done. A release supporting Debian Buster (and CentOS 8 if it's out by then) will be released shortly.
