What changes were made in Star Wars Special Edition?

In 2004, in addition to an extensive and comprehensive hi-definition digital cleanup and restoration job by Lowry Digital, the original trilogy films were changed once again for their release on DVD on September 21. In these new versions of the films, a few changes which had been made for the 1997 Special Editions were removed. Even more changes were made to the films, however. With this release, Lucasfilm created a new high-definition master of the films, which will be used in future releases as well.
