What is your definition of "release code" ? Sticker "Version x.0" on box (as opposed to "x.99") ? :-)
I think that customers are interested only whether software works as expected or not,
which frequently has nothing to do with whether code is labelled as beta or release
(generally; I am not speaking about IB/FB now).
