I exclusively used the beta site. They dumped all of the data as well. Over 190 alerts I had set up are now gone. In addition to no married segment functionality, you now have to manually create individual alerts for each fare class on a single flight vs. entering them all at once on the beta. Very disappointing all around and a significant reduction in features and functionality going back to the old site.

EDIT to post their response:
