Version 2.1.0
-------------
Ganeti 2.1 brings many improvements with it. Major changes:
- Added infrastructure to ease automated disk repairs
- Added new daemon to export configuration data in a cheaper way than
using the remote API
- Instance NICs can now be routed instead of being associated with a
networking bridge
- Improved job locking logic to reduce impact of jobs acquiring multiple
locks waiting for other long-running jobs
Detailed implementation details can be found in the Ganeti 2.1 design
document.

- Added new command to list physical volumes on nodes (``gnt-node
physical-volumes``) and to modify them (``gnt-node modify-volume``)
- Added new ssconf files with master candidate IP address
(``ssconf_master_candidates_ips``), node primary IP address
