Comment:

 Comparing the state isn't too hard - you could probably do so from a
 status plugin that's similar to the MailNotifier.

 What's tricky is to define "previous build" - is that ordered by time, or
 by commit history?  If you're using a non-monotonic version control system
 (e.g., git with unordered sha1's), how do you determine "previous"?  Even
 with svn, if you have a build for r10010 and r10012, do you wait for a
 potential r10011 to arrive before comparing?  What about parallel builds
 where r10012 is on a faster slave and finishes before r10010?  What if two
 builds by a particular builder are for different branches?  If you take
 that into account, what happens if the previous build on a branch has been
 purged from the status history?

 If all of these questions have simple answers for your install of
 Buildbot, then this should be fairly straightforward for you.  For the
 reasons outlined above, such a thing is unlikely to be included in
 Buildbot itself (although I would be happy to see a reference to it
 somewhere on the wiki!)
