So, today I came across interesting message about passenger. It is application server, I guess for python support? Code: [ E 2025-11-13 09:05:14.7129 3695723/T5 age/Cor/SecurityUpdateChecker.h:521 ]: A security update is available for your version (6.0.17) of Phusion Passenger(R). We strongly recommend upgrading to version 6.1.0. Of course I headed to passenger website and deployed appropriate repo: https://www.phusionpassenger.com/do..._upgrade/standalone/install/oss/bookworm.html And that's upgraded passenger to latest version. My question: is there any necessity to keep passenger around if I do not offer python code hosting?
