Core and builtins
-----------------
+- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
+ allows calling unicode() on exceptions classes directly to succeed.
+
- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
Also make sure that every exception class has __module__ set to
'exceptions'.
