Fuel 3.1 with Integrated graphical and command line controls
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

In earlier releases, Fuel was distributed as two packages – “Fuel Web” for 
graphical workflow, and “Fuel library” for command-line based manipulation.  
Starting with this 3.1 release, we’ve integrated these two capabilities into a 
single offering, referred to simply as Fuel.  If you used Fuel Web, you’ll see 
that capability along with its latest improvements to that capability in the the 
Fuel User Interface (UI), providing a streamlined, graphical console that enables 
a point-and-click experience for the most commonly deployed configurations.  
Advanced users with more complex environmental needs can still get command-line 
access to the underlying deployment engine (aka “Fuel Library”).
  
Option to deploy Red Hat Enterprise Linux® OpenStack® Platform
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Mirantis Fuel now includes the ability to deploy the Red Hat Enterprise Linux 
OpenStack Platform (a solution that includes both Red Hat Enterprise Linux and 
the Red Hat OpenStack distribution).  During the definition of a new environment, 
the user will be presented with the option of either installing the Mirantis 
provided OpenStack distribution onto CentOS powered nodes or installing the Red 
Hat provided OpenStack distribution onto Red Hat Enterprise Linux powered nodes.

.. note:: A Red Hat subscription is required to download and deploy Red Hat 
    Enterprise Linux OpenStack Platform.  
	
Mirantis OpenStack Health Check 
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

New in this release is the Mirantis OpenStack Health Check which can be accessed 
through a tab in the Fuel UI.  The OpenStack HealthCheck is a battery of tests 
that can be run against an OpenStack deployment to ensure that it is installed 
properly and operating correctly.  The suite of tests exercise not only the core 
components within OpenStack, but also the added packages included in the Mirantis 
OpenStack distribution.  Tests can be run individually or in groups.  A full list 
of available tests can be found in the documentation.

Ability to deploy properly in networks that are not utilizing VLAN tagging
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

In some environments, it may not be possible or desired to utilize VLANs to 
segregate network traffic. In these networks, Fuel can now be configured through 
the Fuel UI to disable the need for VLAN tagging.  This configuration option is 
available through the Network Settings tab.

Integrated ability to connect to remote nodes via SSH
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The ability to connect to a remote node via SSH is now available from the machine 
details screen.  SSH key management is automatically handled by Fuel, so the user 
need only click on she SSH Console button to connect.

Improved High Availability resiliency
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

To improve the resiliency of the Mirantis OpenStack High Availability reference 
architecture, Fuel now deploys all HA services under Pacemaker, a scalable 
cluster resource manager developed by Clusterlabs.  Additional options in the 
Fuel Library have also been added to Corosync to enable more granular tuning.
