Stable version for GKE frontendconfig(Multi cluster Ingress)

[ranganathand]

Currently i am using 

apiVersion: networking.gke.io/v1beta1 for GKE Frontendconfig along with multi cluster ingress.

so what is stable version available for frontend config. i don't see much insight from google documentation, is there any release calendars?

Note: using front end config to configure sslpolicy

Sadly, that’s still the latest version.
