**This describes proposed changes for a possible Pacemaker 3.0.0 release. Discussion should be directed to the [[ /w/clusterlabs/clusterlabs_mailing_lists/ | users mailing list]].** Pacemaker 3.0 is a proposed major release whose main goal is to remove support for deprecated legacy syntax, in order to improve code maintainability. The expected time frame for the Pacemaker 3.0.0 release would be mid- to late 2024. == Release compatibility == * Rolling upgrades from Pacemaker versions earlier than 2.0.0 would not be supported. (Rolling upgrades from version 2.0.0 and greater should be possible with little to no change.) * Support for connecting to Pacemaker Remote nodes running Pacemaker 1.1.14 or earlier will be dropped. * Cluster nodes running a Pacemaker 1 release will be unable to connect to bundles or Pacemaker Remote nodes running Pacemaker 3.0.0 or later. == Proposed changes == * [[/w/projects/pacemaker/pacemaker_3.0_changes/pacemaker_3.0_configuration_changes/ | Pacemaker 3.0 Configuration Changes]] * [[/w/projects/pacemaker/pacemaker_3.0_changes/pacemaker_3.0_behavioral_changes/ | Pacemaker 3.0 Behavioral Changes]] * [[/w/projects/pacemaker/pacemaker_3.0_changes/pacemaker_3.0_api_changes/ | Pacemaker 3.0 API Changes]]
