Perhaps Maastricht might be a better place to draw the line. But it's not like the changes at Lisbon were trivial; for example, changing unanimous voting to majority was a qualitative change in the character of the organization. My argument is that the GP by lanevorockz was pretty obviously referring to Lisbon, and that the reply by HugoDaniel seemed quite disingenuous in that light.
But the treaty of Lisbon changed almost nothing in reality. At least, not enough to warrant the birth of "Modern EU"
