-* `azurerm_container_group` - previously the value of `PRIVATE_EMPTY` field wouldn't be stored into state file when it is set as empty string in tf config, but the behavior has been updated, and now it would be stored. ([#8096](https://github.com/terraform-providers/terraform-provider-azurerm/issues/8096))
+* `azurerm_container_group` - The `secure_environment_variables` field within the `container` now maps keys with empty values, which differs from previous versions of this provider which ignored empty values [GH-8151]
