Component versions

Kubernetes: v1.16.10
Etcd: v3.4.9
Calico: v3.11.1

Upgrade notes

An upgrade-in-place has not been tested with this release but is believed to work just fine. There are a handful of known issues with large clusters or clusters that use etcd in ENI mode.

If this is use, it is instead recommended to stand up a new cluster and failover to it, using a backup & recovery strategy, if this is something your team hasn't yet practiced then we recommend investigating Velero.

OS Changes

This release switches the host OS from CoreOS to Flatcar as CoreOS is now EOL. This should be a seemless change and we do not expect to see disruption from the change.
