Hello Team,
We are currently configured Nginx controller 1.5.1 in our AKS environment and are planning to upgrade to the latest version. I found below information from the official documentation and not able to find any information regarding the support period.
Could you please let me know if we upgrade ingress controller to 1.6.4 , when it will go out of support ?

Please provide me with any documentation showing the EOL of versions v1.6.4 and latest versions.
