An updated version of Python client library is available from
http://code.google.com/p/google-api-adwords-python-lib/. This release
includes some major updates and a bunch of bug fixes. Some of the
notable ones are (for a full list see ChangeLog):

  - Added support for v12.
  - Control of error handling was passed to end user. On error, an
exception will be raised instead of terminating the script. Thanks to
Don (donspauldingii) for reporting this bug and submitting a patch for
it.
  - Added support for non-ASCII characters. If you see any weird
warnings, add a "# -*- coding: UTF-8 -*-" line right below the
shebang. This should take care of any discrepancies with encoding.

Thanks to everyone who reported bugs and feature requests at
http://code.google.com/p/google-api-adwords-python-lib/issues/list.
