Request Tracker 4.4 reached end of life in November 2025. I’d been running RT 4.4.4 in a container on one of my Linode servers since 2020, and the upgrade to RT 6.0.2 had been sitting in my backlog for months. It’s the kind of task that’s never urgent until it is. You and I both

Today, I noticed that the WordPress Admin Console was complaining that I was using PHP 7.2 which is getting old.
