 Tests
 
+- The "classic" standard tests, which work by comparing stdout to
+  an expected-output file under Lib/test/output/, no longer stop at
+  the first mismatch.  Instead the test is run to completion, and a
+  variant of ndiff-style comparison is used to report all differences.
+  This is much easier to understand than the previous style of reporting.

+- The unittest-based standard tests now use regrtest's test_main()
+  convention, instead of running as a side-effect of merely being
+  imported.  This allows these tests to be run in more natural and
+  flexible ways as unittests, outside the regrtest framework.
