What version are you running?
Review Board 2.0.18

What's the URL of the page containing the problem?
The dashboard

What steps will reproduce the problem?
1. Mark a review as ShipIt
2. Upload a new diff to the review

What is the expected output? What do you see instead?

When a new diff is updated, it's really unexpected that the old ShipIt count would remain, as this wrongfully implies that reviewers have approved of the new diff, when in fact they have not necessarily even seen it. It might mean that a committer could merge the packages into the master repository without realizing that the latest version hasn't been reviewed.

What operating system are you using? What browser?
Fedora 22, Firefox/Chrome

Since 3.0 it is possible to revoke ShipIts. I added this to my extension. After someone posts an update it will revoke any previous ShipIt.
