+\item A new \function{urandom(\var{n})} function
+was added to the \module{os} module, providing access to
+platform-specific sources of randomness such as
+\filename{/dev/urandom} on Linux or the Windows CryptoAPI. The
+function returns a string containing \var{n} bytes of random data.

+\item Another new function: \function{os.path.lexists(\var{path})}
+returns true if the file specified by \var{path} exists, whether or
+not it's a symbolic link. This differs from the existing
+\function{os.path.exists(\var{path})} function, which returns false if
+\var{path} is a symlink that points to a destination that doesn't exist.
