## Version 2.7.1

 *  Fix: Don't do a health check on newly-created connections. This is
    unnecessary work that could put the client in an inconsistent state if the
    health check fails.


## Version 2.7.0

_2015-12-13_

  [overwrite of manual edits to GCP Health Checks](https://github.com/kubernetes/ingress/issues/842)
  managed by the GLBC Ingress Controller. This can cause the health checks to start failing,
  requiring you to reapply the manual edits.
  * This issue does not affect clusters that were already running Kubernetes v1.6.4 or higher.
  * This issue does not affect Health Checks that were left in the configuration

    *  -  the `health` plugin now includes the `lameduck` option by default, which waits for a duration before shutting down.
* Kubeadm now includes CoreDNS version 1.6.5 ([#85108](https://github.com/kubernetes/kubernetes/pull/85108), [@rajansandeep](https://github.com/rajansandeep))
    *  - `kubernetes` plugin adds metrics to measure kubernetes control plane latency.
