A browser tab loads Fulcrum once and then runs that version until somebody reloads it. We've seen shop-floor screens still running a version of Fulcrum more than two months old, which means a shop can sit on behavior we've already changed for weeks after a release.
Every Fulcrum screen now notices when a newer version is out and refreshes itself at a safe moment. Unattended screens — job tracking tablets, time clocks, wall monitors — reload quietly, but only when it's provably safe: nothing open mid-workflow, nothing typed and unsaved, no half-entered quantity. If you're actively working, you get a small banner, and a countdown only in the last few minutes before the deadline.
