## Latest
* Migrate control plane from self-hosted to static pods ([#536](https://github.com/poseidon/typhoon/pull/536))
* Run `kube-apiserver`, `kube-scheduler`, and `kube-controller-manager` as static pods on each controller
* `kubectl` edits to `kube-apiserver`, `kube-scheduler`, and `kube-controller-manager` are no longer possible (change)
* Remove [bootkube](https://github.com/kubernetes-incubator/bootkube), self-hosted pivot, and `pod-checkpointer`
* Update CoreDNS from v1.5.0 to v1.6.2 ([#535](https://github.com/poseidon/typhoon/pull/535))
* Update etcd from v3.3.15 to [v3.4.0](https://github.com/etcd-io/etcd/releases/tag/v3.4.0)
* Recommend updating `terraform-provider-ct` plugin from v0.3.2 to [v0.4.0](https://github.com/poseidon/terraform-provider-ct/releases/tag/v0.4.0)

#### In-place Edits
Typhoon uses a self-hosted Kubernetes control plane which allows certain manifest upgrades to be performed in-place. Components like `apiserver`, `controller-manager`, `scheduler`, `flannel`/`calico`, `coredns`, and `kube-proxy` are run on Kubernetes itself and can be edited via `kubectl`. If you're interested, see the bootkube [upgrade docs](https://github.com/kubernetes-incubator/bootkube/blob/master/Documentation/upgrading.md).
Typhoon uses a static pod Kubernetes control plane which allows certain manifest upgrades to be performed in-place. Components like `kube-apiserver`, `kube-controller-manager`, and `kube-scheduler` are run as static pods. Components `flannel`/`calico`, `coredns`, and `kube-proxy` are scheduled on Kubernetes and can be edited via `kubectl`.
In certain scenarios, in-place edits can be useful for quickly rolling out security patches (e.g. bumping `coredns`) or prioritizing speed over the safety of a proper cluster re-provision and transition.
