 ENHANCEMENTS:
 
+* backend/azurerm: updating the dependencies for the Azure Backend ([#26721](https://github.com/hashicorp/terraform/pull/26721))
 * config: A `required_providers` entry can now contain `configuration_aliases` to declare additional configuration aliases names without requirring a configuration block [GH-27739]
 * config: Terraform will now emit a warning if you declare a `backend` block in a non-root module. Terraform has always ignored such declarations, but previously did so silently. This is a warning rather than an error only because it is sometimes convenient to temporarily use a root module as if it were a child module in order to test or debug its behavior separately from its main backend. ([#26954](https://github.com/hashicorp/terraform/issues/26954))
 * cli: The family of error messages with the summary "Invalid for_each argument" will now include some additional context about which external values contributed to the result. ([#26747](https://github.com/hashicorp/terraform/issues/26747))
