## Announcement A new Cloud Composer release has started on **March 26, 2025**. Get ready for upcoming changes and features as we roll out the new release to all regions. This release is in progress at the moment. Listed changes and features might not be available in some regions yet. ## Announcement All Cloud Composer environment's GKE clusters are set up with **maintenance exclusions** from March 27, 2025 to April 04, 2025\. For more information, see Maintenance exclusions. ## Feature Data lineage in Cloud Composer now uses [OpenLineage](https://airflow.apache.org/docs/apache-airflow-providers-openlineage/stable/guides/user.html). Data lineage support for a specific Airflow operator is now provided by the provider package where the operator is located. See [Supported classes](https://airflow.apache.org/docs/apache-airflow-providers-openlineage/stable/supported%5Fclasses.html) in the `apache-airflow-providers-openlineage` documentation for a list of latest supported operators. For more information about data lineage in Cloud Composer, see [Data lineage with Dataplex](https://cloud.google.com/composer/docs/composer-3/lineage-integration). This feature is gradually rolled out. It will be available in us-west1, us-south1, europe-north1, me-west1, asia-northeast2, asia-southeast2, and africa-south1 regions. We plan to provide this feature in other regions in future releases. ## Fix _(Available without upgrading)_ Fixed an issue with updating maintenance windows when there is an upcoming Cloud Composer 3 infrastructure operation. ## Breaking _(Airflow 2.10.2 and 2.9.3)_ The `apache-airflow-providers-google` package was upgraded to version 14.0.0 in Cloud Composer 2 images and Cloud Composer 3 builds. This package is a new major version where **many previously deprecated Airflow operators are removed**. It is not possible to use these operators in your DAGs. Make sure that you update your DAGs to use up-to-date alternatives of the removed operators.
