PyMongo 3.0 brings a large number of API changes. Be sure to read the changes listed below before upgrading from PyMongo 2.x

Warning: PyMongo no longer supports Python 2.4, 2.5, or 3.1. If you must use PyMongo with these versions of Python the 2.x branch of PyMongo will be minimally supported for some time.

See the full changelog for more information.

If you're not sure what version of PyMongo you're running, consider using the generic tag.
