Minor bug fix release.

Fixes #25

Minor release that adds minimum paramiko library version requirement.

This release brings a slew of updates and new functionality including a new user facing, simplified API.

Changes:

• New user facing API - #14
• Native SSH tunneling support. Removes the need for ProxyCommand to be set in ~/.ssh/config and no longer uses the 'ssh' binary to perform tunelling. #12
• Allow for overriding timeout setting of SSH clients - #16
• In tests, the python 2.6 target has been re-enabled to ensure python 2.6 support is not broken without realising.
• Many more tests, documentation updates and cleanup

Superseeded by 0.70 as 0.7 is < than 0.61..

Bug fix release for #11.

This version adds

• ProxyCommand support - Issue #6
• Reading existing ProxyCommand configuration in ~/.ssh/config - Issue #6
• SSH agent forwarding - Issue #8

Please note that SSH agent forwarding is now enabled by default, a change from previous versions.

If this is not desirable for you then set forward_ssh_agent=False when creating a ParallelSSHClient object.
