  35  *
  36  * By default, external code using Pacemaker headers is allowed to use
  37  * deprecated Pacemaker APIs. If PCMK_ALLOW_DEPRECATED is defined to 0 before
  38  * including any Pacemaker headers, deprecated APIs will be unusable. It is
  39  * strongly recommended to leave this unchanged for production and release
  40  * builds, to avoid breakage when users upgrade to new Pacemaker releases that
  41  * deprecate more APIs. This should be defined to 0 only for development and
  42  * testing builds when desiring to check for usage of currently deprecated APIs.

  48  * The CRM feature set assists with compatibility in mixed-version clusters.
  49  * The major version number increases when nodes with different versions
  50  * would not work (rolling upgrades are not allowed). The minor version
  51  * number increases when mixed-version clusters are allowed only during
  52  * rolling upgrades (a node with the oldest feature set will be elected DC). The
  53  * minor-minor version number is ignored, but allows resource agents to detect
  54  * cluster support for various features.
  55  *
  56  * The feature set also affects the processing of old saved CIBs (such as for
  57  * many scheduler regression tests).
  58  *
  59  * Particular feature points currently tested by Pacemaker code:
  60  *
  61  * >2.1:     Operation updates include timing data
  62  * >=3.0.5:  XML v2 digests are created
  63  * >=3.0.8:  Peers do not need acks for cancellations
  64  * >=3.0.9:  DC will send its own shutdown request to all peers
  65  *           XML v2 patchsets are created by default
  66  * >=3.0.13: Fail counts include operation name and interval
  67  * >=3.2.0:  DC supports PCMK_EXEC_INVALID and PCMK_EXEC_NOT_CONNECTED
