Cluster API v1.12.0 introduces two major features: in-place updates and chained upgrades. In-place updates allow changes to existing machines without deletion and recreation, automatically choosing between immutable rollouts and in-place mechanisms based on the change type. Chained upgrades enable jumping multiple Kubernetes minor versions in a single operation (e.g., v1.33 to v1.35), with Cluster API orchestrating intermediate steps automatically. Both features maintain extensibility through runtime hooks while reducing friction in cluster lifecycle operations. The release emphasizes simplicity—users just update specs and Cluster API handles the optimal execution path.
