8.0 was the release that had more issues for me, as it was the first
version with all the backend work done to make it capable of running
windows.  for that reason I stayed on 7.4 until 8.1.4 or so was out.

8.2 was a nice incremental upgrade, and I migrated to it around 8.2.3
and have been happy every since.
