Passenger 6.0.25

by Camden Narzt

Version 6.0.25 of the Passenger application server has been released. This release fixes an issue where Bundler would try to re-exec the process name instead of the script, and adds a config option to allow reverting to previous routing behaviour, in order to mitigate possible performance regressions.

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

Allow using old routing algorithm

Passenger 6.0.25 adds a config option to allow reverting to previous routing behaviour, in order to mitigate possible performance regressions. This flag is temporary and will become a no-op and will eventually be removed once the routing performance regression has been fixed. Closes GH-2579.

  • Nginx: passenger_old_routing on;
