Pacemaker 2.1 Changes

'''Pacemaker 2.1 is in the early planning stages. No timeline has been determined for when 2.1.0 would be released.'''

Pacemaker 2.1 is a minor Pacemaker release that preserves backward compatibility for rolling upgrades from Pacemaker 1.1.11 or later. As with Pacemaker 2.0, corosync 2 or later is supported as the underlying cluster layer; rolling upgrades are possible if the cluster layer stays at the same corosync major version (2 or 3).

The proposed changes fall into these categories:


 * Pacemaker 2.1 Configuration Changes
 * Pacemaker 2.1 Tool Changes
 * Pacemaker 2.1 API Changes
