- Bug #1115886: os.path.splitext('.cshrc') gives now ('.cshrc', '').
+- unittest now verifies more of its assumptions. In particular, TestCase
+ and TestSuite subclasses (not instances) are no longer accepted in
+ TestSuite.addTest(). This should cause no incompatibility since it
+ never made sense with ordinary subclasses -- the failure just occurred
+ later, with a more cumbersome exception.

- Patch #787789: allow to pass custom TestRunner instances to unittest's
main() function.
