+- doctest refactoring continued.  See the docs for details.  As part of
+  this effort, some old and little- (never?) used features are now
+  deprecated:  the Tester class, the module is_private() function, and the
+  isprivate argument to testmod().  The Tester class supplied a feeble
+  "by hand" way to combine multiple doctests, if you knew exactly what
+  you were doing.  The newer doctest features for unittest integration
+  already did a better job of that, are stronger now than ever, and the
+  new DocTestRunner class is a saner foundation if you want to do it by
+  hand.  The "private name" filtering gimmick was a mistake from the
+  start, and testmod() changed long ago to ignore it by default.  If
+  you want to filter out tests, the new DocTestFinder class can be used
+  to return a list of all doctests, and you can filter that list by
+  any computable criteria before passing it to a DocTestRunner instance.
