Release notes

Sourced from apache-airflow's releases.

Apache Airflow 3.2.1

📦 PyPI: https://pypi.org/project/apache-airflow/3.2.1/ 📚 Docs: https://airflow.apache.org/docs/apache-airflow/3.2.1/ 🛠 Release Notes: https://airflow.apache.org/docs/apache-airflow/3.2.1/release_notes.html 🐳 Docker Image: "docker pull apache/airflow:3.2.1" 🚏 Constraints: https://github.com/apache/airflow/tree/constraints-3.2.1

Significant Changes

• Users who only have read access to DAGs will no longer be able to fetch data from the /dags endpoint, as it now requires additional permissions (DagAccessEntity.RUN, DagAccessEntity.HITL_DETAIL, and DagAccessEntity.TASK_INSTANCE). This change was made because the endpoint returns aggregated data from these multiple entities. Please update your custom user roles to include read access for DAG Runs, Task Instances, and HITL Details if those users should still have access to the /dags endpoint. (#64822)

Improvements

• Allow UI theme config with only CSS overrides, icon only, or empty {} to restore OSS defaults. The tokens field is now optional in the theme configuration. (#64552)
