Has a new Butch Cassidy and the Sundance Kid come out?

dvdverdict.com is showing Butch Cassidy and the Sundance Kid :
Special Edition coming out today, Tuesday, May 11th. I
already have this title, but amazon.com is listing the audio
as 5.1 (?). Is this "new" release identical to the previous
release with the exception of the inclusion of a 5.1 sound
option? Thanks!
