Claude Opus 4.8 shipped today. Here's the upgrade decision tree the announcement skipped — and three workloads that should stay on 4.7.

Opus 4.8 dropped a few hours ago. The announcement is, predictably, all benchmark deltas and SWE-bench numbers. The decision teams actually have to make this week is not 'is 4.8 better than 4.7' — it is 'which of my running workloads should move, which should stay, and what is the regression risk on the ones I move'. Here is the upgrade decision tree I am giving my own team, with three workload types I am explicitly keeping on 4.7 until at least mid-July.
