#### kubectl:

- Kubelet now exposes `/debug/flags/v` to allow dynamically setting glog logging level.  For example, to change glog level to 3, you only have to send a PUT request like `curl -X PUT http://127.0.0.1:8080/debug/flags/v -d "3"`.

- Added a path `/header?key=` to `agnhost netexec` allowing one to view what the header value is of the incoming request.

  Ex:
  ```
  $ curl -H "X-Forwarded-For: something" 172.17.0.2:8080/header?key=X-Forwarded-For
  something
  ```

- API servers using the default Google Compute Engine bootstrapping scripts will have their insecure port (`:8080`) disabled by default. To enable the insecure port, set `ENABLE_APISERVER_INSECURE_PORT=true` in kube-env or as an environment variable.
