## edge-20.9.1 This edge release contains an important proxy update that allows linkerd to continue to operate normally in HA during node outages. We're also adding full Kubernetes 1.19 support! * Improved the proxy's error handling for DNS errors encountered when discovering control plane addresses, which can be common during installation, before all components have been started * The destination and identity services had to be made headless in order to support that new controller discovery (which now can leverage SRV records) * Use SAN fields when generating the linkerd webhook configs; this completes the Kubernetes 1.19 support which enforces them * Fixed `linkerd check` for multicluster that was spuriously claiming the absence of some resources * Improved the injection test cleanup (thanks @zhouhao3!) * Added ability to run the integration test suite using a cluster in an ARM architecture (thanks @aliariff!)
