- After the user added a duplicate resource operation, Pacemaker configuration became invalid. With this update, pcs does not add the operation and instead informs the user that the same operation already exists.
- The user could not manage Red Hat Enterprise Linux 6 clusters using the pcsd web UI running on a Red Hat Enterprise Linux 7 host. The bug has been fixed, and it is now possible to add or create clusters in this situation. Note that the pcsd web UI is still not available on Red Hat Enterprise Linux 6 hosts.
- After the user displayed the list of STONITH devices or resources, their locations were not included. Now, the list also contains the locations of the devices and resources.
- The "pcs resource describe" command displayed the resource agent description on one line, which made it difficult to read. Now, pcs displays the description as it is defined in the agent.
- After displaying information about a fence agent, pcs showed the description of the options but not the description of the fence agent itself. Now, the fence agent description is displayed as well in this situation.

- Previously, pcs stopped cluster nodes sequentially one at a time, which caused the cluster resources to be moved from one node to another pointlessly. Consequently, the stop operation took a long time to finish. Also, losing the quorum during the process could result in node fencing. With this update, pcs stops the nodes simultaneously, preventing the resources from being moved around pointlessly and speeding up the stop operation. In addition, pcs prints a warning if stopping the nodes would cause the cluster to lose the quorum. To stop the nodes in this situation, the user is required to add the "--force" option.

- The "pcs status --full" command did not output the node attributes and migration summary. Similarly, the "pcs config" command did not display the resource and operation defaults. Both commands have been modified to display this information.
- After the user attempted to ban or clear a clone resource, pcs displayed an error message stating the resource did not exist. With this update, pcs supports banning and clearing clone resources. The "pcs resource ban" command creates a constraint on a cloned resource, and the "pcs resource clear" command removes that constraint.
- When using the User Datagram Protocol unicast (UDPU) transport, the cluster is required to be restarted in order for the node to be added or removed properly. Previously, pcs did not inform the user about this requirement. Now, pcs warns the user to restart the cluster.
- After the user removed a node from a cluster, the cluster could fence the removed node. This update modifies pcs to reload the cluster.conf file after adding or removing a node, thus fixing the bug.
- This update adds support for configuring the Redundant Ring Protocol (RRP) and setting Corosync options. The user can now configure a cluster with RRP and set up corosync options.
- The clufter package is now installed as a pcs dependency. With clufter installed, pcs is able to import CMAN configuration from the cluster.conf file and convert it into Pacemaker configuration.
