When the IAM condition will be available in google provider

We are trying to use the IAM conditions for our gcp usecase using Terraform. Currently the IAM condition is available only in the “google-beta” provider. Is there any time line for when it will be available in google provider?

Code snippet :
resource “google_project_iam_member” “project” {
project = “your-project-id”
role = “roles/editor”
member = “user:jane@example.com

condition {
title = “expires_after_2019_12_31”
description = “Expiring at midnight of 2019-12-31”
expression = “request.time < timestamp(“2020-01-01T00:00:00Z”)”
