Looking at the bug reports forum, it looks like there aren't too many bugs reported for 7.3b5 so far. However, once 7.3b5 goes into public beta, then the bugs can be tracked down more easily.

One bug that went unnoticed from 7.3b4 is that the search page still shows "Maximum date range is 4". This has already been posted at the bug reports forum:
