Passenger 6.0.24

by Camden Narzt

Version 6.0.24 of the Passenger application server has been released. This release adds packages for Ubuntu 24.10 (Oracular), and improves rolling restart performance.

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

Rolling restart improvements

We changed the way we route requests during a Rolling Restart in order to provide better performance and reliability. Instead of picking the least-busy process to route requests to, we now prioritize new processes first. During a rolling restart, this new behavior leads to more efficient utilization of application caches, faster validation of new rollouts, and faster recovery from problematic deployments. Closes GH-2551.
