- SF bug 705231: builtin pow() no longer lets the platform C pow()
raise -1.0 to integer powers, because (at least) glibc gets it wrong
in some cases. The result should be -1.0 if the power is odd and 1.0
if the power is even, and any float with a sufficiently large exponent
is (mathematically) an exact even integer.
+- SF bug 759227: A new-style class that implements __nonzero__() must
+ return a bool or int (but not an int subclass) from that method. This
+ matches the restriction on classic classes.

- The encoding attribute has been added for file objects, and set to
the terminal encoding on Unix and Windows.

Extension modules
-----------------
- the socket module has a new exception, socket.timeout, to allow
timeouts to be handled separately from other socket errors.
+- SF bug 751276: cPickle has fixed to propagate exceptions raised in

+- cPickle Pickler and Unpickler objects now participate in garbage
+ collection.

- mimetools.choose_boundary() could return duplicate strings at times,
especially likely on Windows. The strings returned are now guaranteed
unique within a single program run.
