Message:

Commits for ticket 770 concerning the display of multiple values for a metadata (like dc.Title) when classified by that metadata. So when the user browses by dc.Title, they no longer merely see a doc listed once for each dc.Title assigned but under the same (first retrieved) dc.Title, but they should now see the doc listed once for each dc.Title assigned to it with a different dc.Title value each time.
