*   You can now use a new supported service annotation for AWS clusters, `service.beta.kubernetes.io/aws-load-balancer-ssl-negotiation-policy`, which lets you specify which [predefined AWS SSL policy](http://docs.aws.amazon.com/elasticloadbalancing/latest/classic/elb-security-policy-table.html) you would like to use.

* kubernetes-worker juju charm: Added support for setting the --enable-ssl-chain-completion option on the ingress proxy.

  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))

* Mount additional paths required for a working CA root, for setups where /etc/ssl/certs doesn't contains certificates but just symlink. ([#59122](https://github.com/kubernetes/kubernetes/pull/59122), [@klausenbusk](https://github.com/klausenbusk))
