Mutation means the same thing now as it did back then. What has changed is that we now understand how it works. The concept of punctuated equilibrium was introduced in 1972. It is the leading theory based on present understanding. I'm not sure what you mean by "less defensible."

That a hypothesis that has no feasible molecular basis can be called "leading" is a mark of the bankruptcy of Darwinian evolutionary theory.

Punctuated equilibrium still involves gradual Darwinian change, but over very short periods of time compared to the long periods where the species is adapted as well as it can be (without major, unlikely changes) to its present environment.

I'm hoping that gradually over a very short period of time folks will realize the contradiction in terms that is called "punctuated equilibrium". It has no feasible molecular basis. Without such, it might as well be fairy dust for its explanatory power. But gradual fairy dust, that operates over very short periods of time.

The pertinent question remains: at the molecular level, how?
