I don't think so, really. There's the change in style, of course, and in every political tendancy there are evolutions in policy over time. And the disappearance of the Soviet Union removed a major funding source and meant Georges Marchais' visits to Moscow wouldn't be repeated by Robert Hue.

The evolution to Euro-communism happened under Marchais, not after him, his statements on Afghanistan (and he in retrospect turns out to have been 100% right about Soviet intervention there) being used notably by the PS for electoral reasons to prove otherwise. Similar evolutions were occuring elsewhere, PCI notably.

The big changes came in the eastern parties, and Gysi is emblematic of this.
