in kube-apisever and kube-controller-manager pods. Instead, it shifted to supporting the
  mounting of /etc/pki/ca-trust and /etc/pki/tls/certs. The locations /etc/ca-certificate,
  /usr/share/ca-certificates, /usr/local/share/ca-certificates, and /etc/ssl/certs continued
  to be supported. ([#124361](https://github.com/kubernetes/kubernetes/pull/124361), [@neolit123](https://github.com/neolit123))

* Align the hyperkube image to support running binaries at /usr/local/bin/ like the other server images ([#41017](https://github.com/kubernetes/kubernetes/pull/41017), [@luxas](https://github.com/luxas))

* Portability across systems has been increased by the use of `/usr/bin/env` in all script shebangs. ([#62657](https://github.com/kubernetes/kubernetes/pull/62657), [@matthyx](https://github.com/matthyx))
* You can now use `kubectl api-resources` to discover resources.
