Special special edition
As I posted a while back, the original (well, Special Edition thereof) Star Wars trilogy will be heading to DVD this September. And it will be worth the wait, because Lucas has even more changes:

Much work has been done to fix some mistakes about Han Solo. "For some reason, Han was portrayed as a rogue in the original versions. That was never intended," Lucas explained. "We’ve been doing some work to show him as the true hero that he is. For instance, we’ve put in a scene where he saves some cute puppies and kittens from a runaway landspeeder."

Well, I'm glad that's been cleared up. It always did bother me that Solo was just too darn rebellious.
