Don't apply WordPress major releases on day one — the "x.0.1 rule" and a calibration framework

The companion to the seven things to check before a WordPress major upgrade is the question that comes right after: when do you actually apply it? A new WordPress major drops today. Do you ship it to production tonight? Tomorrow? In a week? Hold for the next scheduled monthly maintenance? This call tends to live in tribal knowledge, but a few clear axes combined together give you a calibration framework you can apply every time without re-deciding from scratch. Here are five axes worth using. Premise — majors are not security patches The first thing to anchor: a major upgrade is not a security patch . WordPress ships security fixes via minor releases ( 6.4.1 → 6.4.2 , 6.5.0 → 6.5.1 — the second-digit bumps ). Those are same-day apply by default . Major releases ( 6.4 → 6.5 , eventually some 6.x → 7.0 ) carry new features and API changes; they aren't released to be applied immediately for security reasons. Without this distinction, the felt urgency of " we have to apply this for security " pushes you to rush majors that should wait. Minors immediately, majors by judgment — that separation is the first rule worth writing down. Axis 1 — wait for x.0.1 For essentially every major release, x.0.1 (the first patch release) lands within 1–3 weeks and absorbs the critical bugs that surfaced after launch. Past examples have included things like "the admin goes white under specific settings," "a particular theme breaks the block editor," "DB migration stalls in specific environments." Nobody hit these on launch day; they emerged as the world started using it for days or weeks. Just waiting for x.0.1 instead of x.0 sidesteps most of those launch-window bugs. For the first few weeks after a major lands, the world's WordPress installations are effectively running the beta test . Being downstream of the people who hit the mines is the rational position for a maintenance practice. Axis 2 — wait until major plugin vendors update "Tested up to" The thing that breaks most after a majo
