Created a new issue for one of the newer features tied to this CAPI release:

• Add support for MachinePool Machines in CAPP #680

More detail from the upstream 1.5 release:

• MS preflight checks to improve cluster stability (behind feature gate).
• Support for concurrent MachineDeployment upgrades in classy clusters.
• Support for add-on providers in clusterctl.
• Performance improvements when using CAPI at scale, new dev-tools and a new in-memory infrastructure provider for scale testing.
• MachinePool Machines improve MachinePool observability.
  clusterctl plugins allow custom code to be called from clusterctl.
• More metrics have been enabled through a custom Kube State Metrics config, and example Grafana, Prometheus and other observability tool configurations have been added to the repo.
• Cluster controller now avoids double rollouts during Kubernetes upgrades of classy clusters.

ClusterAPI Add-on Provider support can assist in how templates are offered. For example:

• [feat]: add cluster template, use CAAPH to install cilium for the CNI linode/cluster-api-provider-linode#96
• Use CAAPH to install Helm charts in e2e tests kubernetes-sigs/cluster-api-provider-azure#3736
