  - In 2.2a3, __new__ would only see sequential arguments passed to the
    type in a constructor call; __init__ would see both sequential and
!   positional arguments.  This made no sense whatsoever any more, so
    now both __new__ and __init__ see all arguments.

  Tests
  
  Windows
  
  - Large file support now also works for files > 4GB, on filesystems
!   that support it (NTFS under Windows 2000).

  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.
+ 
+ - regrtest.py is much better integrated with unittest and doctest now,
+   especially in regard to reporting errors.
