+ \item A new type object, \class{basestring}, has been added.
+ Both 8-bit strings and Unicode strings inherit from this type, so
+ \code{isinstance(obj, basestring)} will return \constant{True} for
+ either kind of string. It's a completely abstract type, so you
+ can't create \class{basestring} instances.
+
+ \item Most type objects are now callable, so you can use them
+ to create new objects such as functions, classes, and modules. (This
+ means that the \module{new} module can be deprecated in a future
+ Python version, because you can now use the type objects available
+ in the \module{types} module.)
+ % XXX should new.py use PendingDeprecationWarning?
+ For example, you can create a new module object with the following code:
+
+ \begin{verbatim}
+ >>> import types
+ >>> m = types.ModuleType('abc','docstring')
+ >>> m
+ <module 'abc' (built-in)>
+ >>> m.__doc__
+ 'docstring'

+ \item The \module{socket} module now supports timeouts. You
+ can call the \method{settimeout(\var{t})} method on a socket object to
+ set a timeout of \var{t} seconds. Subsequent socket operations that
+ take longer than \var{t} seconds to complete will abort and raise a
+ \exception{socket.error} exception.
+
+ (The original timeout implementation was by Tim O'Malley. Michael
+ Gilfix integrated it into the Python \module{socket} module, after the
+ patch had undergone a lengthy review. After it was checked in, Guido
+ van~Rossum rewrote parts of it. This is a good example of the free
