Managed Service for Apache Airflow Releases Stability and Build Updates
Google Cloud has begun rolling out a new release for its Managed Service for Apache Airflow (Cloud Composer) on August 10, 2026. This update enhances web server stability in Gen 3 environments by aligning worker calculations with recent Airflow versions and introduces new Airflow build images for both Gen 3 and Gen 2. Key changes include the blocking of the `[api]rbac_bindings` configuration option for specific Airflow versions.
