Libcloud 0.14.1 has been release recently. Among other bug fixes, improvements and new features, this release also includes a brand new compute driver for CloudSigma API 2.0 with an extensive documentation.

If you want to learn more about this new driver, I encourage you to check a guest post I wrote on the CloudSigma blog which shows some examples of how to use this new driver - CloudSigma API v2.0 is now supported in Libcloud.
