API mismatch Cassandra and Pycassa versions

Hi All,

I was trying to connect to cassandra using the pycassa module. Looks like
there is a API cersion mismatch. Any ideas where I can get the right version
of the APIs?

I am using:
INFO 22:11:50,860 Cassandra version: 0.7.0-beta2
INFO 22:11:50,861 Thrift API version: 17.1.0

Error message on python prompt:

[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.

Hmm, I thought the Thrift API was moved to 18 before beta2 was released.

I'll make a matching release for pycassa in just a moment.  Thanks for the
notice.

By the way, there is a pycassa specific mailing list,
pycassa-discuss@googlegroups.com
