+- Issue #2235: Added Py3k warnings for types which will become unhashable
+ under the stricter __hash__ inheritance rules in 3.0. Several types
+ which did not meet the rules for hash invariants and were already
+ unhashable in 3.0 have now been explicitly flagged as unhashable in
+ 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
+ xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
+
- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
imported into the module but exposed as part of the module's API.
