+
+FEATURES:
+* **New Resource:** `google_monitoring_monitored_project` ([#10153](https://github.com/hashicorp/terraform-provider-google/pull/10153))
+* **New Resource:** `google_org_policy_policy` ([#10111](https://github.com/hashicorp/terraform-provider-google/pull/10111))
+
+IMPROVEMENTS:
+* cloudbuild: added field `service_account` to `google_cloudbuild_trigger` ([#10159](https://github.com/hashicorp/terraform-provider-google/pull/10159))
+* composer: added field `scheduler_count` to `google_composer_environment` ([#10158](https://github.com/hashicorp/terraform-provider-google/pull/10158))
