MAAS 1.7.1

MAAS 1.7.1 Final Release Notes

Minor feature improvements
New CentOS Release support.
Further to the work done in the 1.7.0 MAAS Release, MAAS now supports uploading various versions of CentOS. Previously MAAS would only officially support 6.5.

Power Monitoring for Seamicro 15000, Cisco UCS and HP Moonshot Chassis
Further the work done in the 1.7.0 MAAS release, it now supports power query and monitoring for the Seamicro 15000 Chassis, the Cisco UCS Chassis Manager and the HP Moonshot Chassis Manager.

Node Listing Page and Node Event Log live refresh
The Node Listing page and the Node Event Log now have live refresh every 10 seconds. This allows MAAS to display the latest node status and events without forcing a browser refresh.

IP Address Reservation
The static IP address reservation API now has an optional "mac" parameter. Specifying a MAC address here will link the new static IP to that MAC address. A DHCP host map will be created for the MAC address. No other IPs may be reserved for that MAC address until the current one is released.
