* FAB provider 1.2.1 only affected Airflow 2.9.3 (earlier and later versions of Airflow are not affected)

* FAB provider 1.2.0 affected all versions of Airflow.

Users who run Apache Airflow 2.9.3 are recommended to upgrade to Apache Airflow Providers FAB version 1.2.2 which fixes the issue.

Users who run Any Apache Airflow version and have FAB provider 1.2.0 are recommended to upgrade to Apache Airflow Providers FAB version 1.2.2 which fixes the issue.

Also upgrading Apache Airflow to latest version available is recommended.

Note: Early version of Airflow reference container images of Airflow 2.9.3 and constraint files contained FAB provider 1.2.1 version, but this is fixed in updated versions of the images.
