The \module{filecmp} module defines the following functions:
-\begin{funcdesc}{cmp}{f1, f2\optional{, shallow\optional{, use_statcache}}}
+\begin{funcdesc}{cmp}{f1, f2\optional{, shallow}}
Compare the files named \var{f1} and \var{f2}, returning \code{True} if
they seem equal, \code{False} otherwise.
Unless \var{shallow} is given and is false, files with identical
\function{os.stat()} signatures are taken to be equal.
-\versionchanged[\var{use_statcache} is obsolete and ignored.]{2.3}
Files that were compared using this function will not be compared again
unless their \function{os.stat()} signature changes.
\end{funcdesc}
\begin{funcdesc}{cmpfiles}{dir1, dir2, common\optional{,
- shallow\optional{, use_statcache}}}
+ shallow}}
Returns three lists of file names: \var{match}, \var{mismatch},
\var{errors}. \var{match} contains the list of files match in both
directories, \var{mismatch} includes the names of those that don't,
the comparison could not be done for some reason.
The \var{common} parameter is a list of file names found in both directories.
-The \var{shallow} and \var{use_statcache} parameters have the same
-meanings and default values as for \function{filecmp.cmp()}.
+The \var{shallow} parameter has the same
+meaning and default value as for \function{filecmp.cmp()}.

-------
+- the filecmp module no longer uses the deprecated use_statcache argument.

- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
extended or overridden by subclasses. Formerly, the subclassed method would
be ignored by the rest of the module. (Bug #1078905).
