Recent Items bug
We have just upgraded SDP from 7610 to 8004 and found a change / bug. When looking at the lists of requests, on the left side there is Recent Items. If that is expanded and we click on a ticket either via the recent items or the main list, that recent items list is no longer expanded. As such we are constantly having to expand it manually. This was not the case on 7610.
Since our upgrade when from 7610 to 7611 to 8000 to 8004 at the same time, I can't tell you which upgrade level made that change.
