Updated pytwitter to 0.4.1 and uploaded to pypi and google code. There's only one change:
- Add POST exceptions for statuses_retweet and report_spam methods.

pytwitter 0.5 will have a few more changes:
- I've done away with POST-only methods. All requests will be POSTed, and if a 400 is returned by the server, the request will be retried as a GET. Not ideal (really the server should reply with a 405), but better than hand-maintaining a list of POST methods.

- Stop using string concatenation to produce URLs and query strings.

- Use the new API URL (api.twitter.com) and support versioning. Mostly meaningless until versions other than '1' exist.

- Some cosmetic changes.
