We have our clusters configured to use Custom CA Trusts, per the Hashicorp docs this parameter is not available with 4.x versions of the provider, this was based on the request from Microsoft:

“In order to provide a more reliable experience when using the Azure Provider, Microsoft has requested that the AKS resource only use a stable API version. Starting in version 4.0 of the AzureRM provider, Microsoft and HashiCorp have agreed to switch to the AKS stable APIs. This means that some preview features that are exposed in 3.x will no longer be available in 4.x. The following properties will no longer be available in 4.x:”

We are currently using version 3.x of the provider and have no immediate need to upgrade the provider from 3.X -> 4.X, however as this is a potential showstopper in the future, can we get confirmation that once out of preview the feature will be available through a future terraform release and there will be no breaking changes therefore allowing it to continue to function as normal for customers

Would you have any timeline on when Custom CA Trusts will move out of preview? 😊
