Hi, Andrew!

Just following up; have you had a chance to consider this question?

I'm also thinking a fourth option could be:

d. Don't try to get close to the known-problems page of old.  Just use
   the latest stable release.  If you run into a problem, check the bug
   reports for the next milestone in the series and commits for the next
   release to see if the problem has already been fixed and apply an
   appropriate patch if so.

Thanks!

Lewis
