* including any Pacemaker headers, deprecated APIs will be unusable. It is
* strongly recommended to leave this unchanged for production and release

* The CRM feature set assists with compatibility in mixed-version clusters.
* The major version number increases when nodes with different versions
* would not work (rolling upgrades are not allowed). The minor version
* number increases when mixed-version clusters are allowed only during
* rolling upgrades (a node with the oldest feature set will be elected DC). The
* minor-minor version number is ignored, but allows resource agents to detect
* cluster support for various features.
*
* The feature set also affects the processing of old saved CIBs (such as for
* many scheduler regression tests).
*
* Particular feature points currently tested by Pacemaker code:
*
* >2.1: Operation updates include timing data
* >=3.0.5: XML v2 digests are created
* >=3.0.8: Peers do not need acks for cancellations
* >=3.0.9: DC will send its own shutdown request to all peers
* XML v2 patchsets are created by default
* >=3.0.13: Fail counts include operation name and interval
* >=3.2.0: DC supports PCMK_EXEC_INVALID and PCMK_EXEC_NOT_CONNECTED
* >=3.19.0: DC supports PCMK__CIB_REQUEST_COMMIT_TRANSACT
