About Istios version choice

I have a question about the Istio version. My Kubernets version is V1.11. What is the most recommended Istio version? I think it is Istio version v1.1 on the official website.

It is recommended that you update both kubernetes and Istio. Istio 1.1 has not been supported for some time and does contain many known vulnerabilities. It is advised that you do upgrade.

Based on your suggestion, what version of Kubernetes and Istio should I use?

minimum Kubernetes 1.16 and Istio 1.7 as support for istio 1.6 is now end of life
