"Rapunzel" -er... "Tangled"

I noticed today, on my daily perusal through Disney-related websites, that Rapunzel has been removed from the Walt Disney Animation Studios website. I ALSO noticed that on the Walt Disney Animation Studios Facebook that in a caption to new art from the movie, the movie was called "Tangled".
Not sure why the name changed, haven't heard or read anything official...or unofficial for that matter!
Here's the new image, I enjoy it greatly:


Click the image to go to the Walt Disney Animation Studio Facebook and read the caption for this picture written by Roy Conli, the producer of "Disney's next animated film". Perhaps it was between names when he wrote that?
