| Limited support versions will be supported with security and critical bug fix only. |
| EOL versions will not get any fixes nor support. |
| We **highly** recommend installing the latest Airflow release which has richer features. |

| |
| Support for Python and Kubernetes versions |
| `````````````````````````````````````````` |
| |
| As of Airflow 2.0 we agreed to certain rules we follow for Python and Kubernetes support. |
| They are based on the official release schedule of Python and Kubernetes, nicely summarized in the |
| `Python Developer's Guide <https://devguide.python.org/#status-of-python-branches>`_ and |
| `Kubernetes version skew policy <https://kubernetes.io/docs/setup/release/version-skew-policy>`_. |
| |
| 1. We drop support for Python and Kubernetes versions when they reach EOL. We drop support for those |
| EOL versions in main right after EOL date, and it is effectively removed when we release the |
| first new MINOR (Or MAJOR if there is no new MINOR version) of Airflow |
| For example for Python 3.6 it means that we drop support in main right after 23.12.2021, and the first |
| MAJOR or MINOR version of Airflow released after will not have it. |
| |
| 2. The "oldest" supported version of Python/Kubernetes is the default one. "Default" is only meaningful |
| in terms of "smoke tests" in CI PRs which are run using this default version and default reference |
| image available in DockerHub. Currently ``apache/airflow:latest`` and ``apache/airflow:2.0.2`` images |
| are both Python 3.6 images, however the first MINOR/MAJOR release of Airflow release after 23.12.2021 will |
| become Python 3.7 images. |
| |
| 3. We support a new version of Python/Kubernetes in main after they are officially released, as soon as we |
| make them work in our CI pipeline (which might not be immediate due to dependencies catching up with |
| new versions of Python mostly) we release a new images/support in Airflow based on the working CI setup. |
