## 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))

    // Setting a low transfer speed ensures that stream discarding will time out.

    transferKind.setBody(builder, "ABCDE\nFGHIJKLMNOPQRSTUVWXYZ", 1024)

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

     * 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.

// 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

- Kubeadm: ensure that Pods from the upgrade preflight check `CreateJob` are properly terminated after a timeout. ([#127333](https://github.com/kubernetes/kubernetes/pull/127333), [@yuyabee](https://github.com/yuyabee)) [SIG Cluster Lifecycle]

     * build</a>.)

     * <p>Be careful when targeting an older SDK than you are building against (most commonly when
     * building for Android): Ensure that any object you pass implements the interface not just in
     * your current SDK version but also at the oldest version you support. For example, <a

        /* 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.
