There is more changes thant those 4 known changes (ex: the invasion of Naboo was rerendered with different ships, the external view of Palpatine’s office was deleted, the sound was totally remixed) , but it is probably not the point of this discussion.
Ah, forgot about the Naboo invasion. After all these years my memory is a little blurry, but I want to say the view from the window of Theed Palace was re-done? Or are there other shots I’m forgetting about?
Yes, there are other shots. Ex: http://www.framecompare.com/image-compare/screenshotcomparison/1B01NNNU
