You’ve been lucky 🙂 there are a couple of sites I have that I cannot update to ACF5 because I’m using a some of the addons in the WP repo that haven’t been updated. Pretty popular ones so I’m hoping that will change when ACF5 is officially released. Not sure what I’ll do if they aren’t. I’d say that I’ll end up doing it myself but that all depends on time… until some future WP core update breaks ACF4, then it’ll be a mad scramble 😛
