The Python FlickrAPI kit has just been released. The new features are:
Using auth_callback=False when authentication is actually required now raises a FlickrError exception.
The implementation uses self.flickr_host so that subclasses can override the API URLs.
Support for short URLs was added.
Of course the Python FlickrAPI kit is completely dynamic, and so it always supports any new FlickrAPI functionality as soon as it is released by the Flickr team.
