[Release] DataStax Python Driver 3.21.0 for Apache Cassandra

[Alan Boudreault]

Hi,

Today we've released Python Driver 3.21.0 for Apache Cassandra. This release marks
an important milestone: the unification of the OSS and DSE drivers (including
the Graph Extension).

For more details about this unified driver, please refer to our blog post:

https://www.datastax.com/blog/2020/01/better-drivers-for-cassandra

- For existing cassandra-driver users, there is no noticeable change except a
  new dependency: geomet which is required for DSE geo types.

- For dse-driver users: make sure to follow our upgrading guide to migrate your
  applications to this new driver: https://docs.datastax.com/en/developer/python-driver/latest/upgrading/


In addition, this release also includes other new features: wheel binaries for faster installation,
Python 3.8 support, the Twisted+Evenlet cloud support and asynchronous queries execution with
the Graph Fluent API.


You can find the new docs for these releases here:
