+- wsgiref now implements and validates PEP 3333, rather than an experimental
+  extension of PEP 333.  (Note: earlier versions of Python 3.x may have
+  incorrectly validated some non-compliant applications as WSGI compliant;
+  if your app validates with Python <3.2b1+, but not on this version, it is
+  likely the case that your app was not compliant.)
