 Notes for Windows Users
 =======================
 
 These are just minimal notes.  The manual contains more detailed
 information.
 
 Requirements
 ------------
 
 IPython runs under (as far as the Windows family is concerned):
 
 - Windows XP (I think WinNT/2000 are ok): works well.  It needs:
 
   * PyWin32, the win32 Python extensions from
     http://starship.python.net/crew/mhammond.
 
   * Gary Bishop's readline from 
     http://sourceforge.net/projects/uncpythontools.
     
   * This in turn requires Tomas Heller's ctypes from
     http://starship.python.net/crew/theller/ctypes.
 
 - Windows 95/98/ME: I have no idea. It should work, but I can't test.
 
 - CygWin environments should work, they are basically Posix.
 
-It needs Python 2.2 or newer.
+It needs Python 2.3 or newer.
 
 
 Installation
 ------------
 
 Double-click the supplied .exe installer file.  If all goes well, that's all
 you need to do. You should now have an IPython entry in your Start Menu.
 
 In case the automatic installer does not work for some reason, you can
 download the ipython-XXX.tar.gz file, which contains the full IPython source
 distribution (the popular WinZip can read .tar.gz files). After uncompressing
 the archive, you can install it at a command terminal just like any other
 Python module, by using python setup.py install'. After this completes, you
 can run the supplied win32_manual_post_install.py script which will add
 the relevant shortcuts to your startup menu.
