Perhaps part of the confusion between you and Chris is that you should never have had the sentence <require'stdlib'> in any version of J that used the the standard profile. This bad sentence happened to have no effect in J6, but that doesn't meet it deserves special treatment in J7. I think the fix is for you to remove this bad sentence from all your scripts and then move forward.
