- If upgrading Cluster Federation components from 1.3.x, please ensure your cluster name is a valid DNS label (#30956, @nikhiljindal)

## Changelog since v1.5.5

### Other notable changes

* kube-up (with gce/gci and gce/coreos providers) now ensures the authentication token file contains correct tokens for the control plane components, even if the file already exists (ensures upgrades and downgrades work successfully) ([#43676](https://github.com/kubernetes/kubernetes/pull/43676), [@liggitt](https://github.com/liggitt))

    /**
     * Ensures tree connection is established with optimized connection reuse.
     * @return active tree handle
     * @throws CIFSException if connection fails
     *
     */

     * Sum per-segment modCounts to avoid mis-reporting when elements are concurrently added and
     * removed in one segment while checking another, in which case the table was never actually
     * empty at any point. (The sum ensures accuracy up through at least 1<<31 per-segment
     * modifications before recheck.) Method containsValue() uses similar constructions for
     * stability checks.

- Kubeadm: Ensured waiting for `apiserver` uses a local client that doesn't reach to the control plane endpoint and instead reaches directly to the local API server endpoint. ([#134265](https://github.com/kubernetes/kubernetes/pull/134265), [@neolit123](https://github.com/neolit123))...

// This implementation of the PUT operation adds an object to a bucket
// while reading the object from another source.
// Notice: The S3 client can send secret keys in headers for encryption related jobs,
// the handler should ensure to remove these keys before sending them to the object layer.
// Currently these keys are:
//   - X-Amz-Server-Side-Encryption-Customer-Key
//   - X-Amz-Copy-Source-Server-Side-Encryption-Customer-Key

        /* JCIFS will build a composite list of shares if the target host has
         * multiple IP addresses such as when domain-based DFS is in play. Because
         * of this, to ensure that we query each IP individually without re-resolving
         * the hostname and getting a different IP, we must use the current addresses
         * IP rather than just url.getHost() like we were using prior to 1.2.16.
