When did provider begin applying roles/spanner.databaseUser with monitoring.timeSeries.create?

[apaca18]

Question

Google recently added the monitoring.timeSeries.create permission to the predefined IAM role roles/spanner.databaseUser as noted in the Cloud Spanner IAM documentation.

We manage IAM via Terraform (using the hashicorp/google provider), and we're trying to determine as follows:

In which version of the provider was the new permission reflected in role bindings (i.e., when assigning roles/spanner.databaseUser to a service account via Terraform, the account gets monitoring.timeSeries.create)?

Thanks!
