Journey Between Worlds by Sylvia Engdahl is an example of where the author updated the book in a way that works. It's a sci-fi YA novel primarily set on Mars in the future, and was originally published in 1970. When the author rereleased it in 2006, it was with updated descriptions of Mars and updated references to computer technology. The story itself doesn't change, just some minor details that might throw someone out of the story.
