Apache Airflow 2.7.0

Significant Changes

Remove Python 3.7 support (#30963)

As of now, Python 3.7 is no longer supported by the Python community. Therefore, to use Airflow 2.7.0, you must ensure your Python version is either 3.8, 3.9, 3.10, or 3.11.

Old Graph View is removed (#32958)

The old Graph View is removed. The new Graph View is the default view now.

The trigger UI form is skipped in web UI if no parameters are defined in a DAG (#33351)

If you are using dag_run.conf dictionary and web UI JSON entry to run your DAG you should either:

• Add params to your DAG <https://airflow.apache.org/docs/apache-airflow/stable/core-concepts/params.html#use-params-to-provide-a-trigger-ui-form>_
• Enable the new configuration show_trigger_form_if_no_params to bring back old behaviour

The "db init", "db upgrade" commands and "[database] load_default_connections" configuration options are deprecated (#33136).

Instead, you should use "airflow db migrate" command to create or upgrade database. This command will not create default connections. In order to create default connections you need to run "airflow connections create-default-connections" explicitly, after running "airflow db migrate".

In case of SMTP SSL connection, the context now uses the "default" context (#33070)

The "default" context is Python's default_ssl_contest instead of previously used "none". The default_ssl_context provides a balance between security and compatibility but in some cases, when certificates are old, self-signed or misconfigured, it might not work. This can be configured by setting "ssl_context" in "email" configuration of Airflow.

Setting it to "none" brings back the "none" setting that was used in Airflow 2.6 and before, but it is not recommended due to security reasons ad this setting disables validation of certificates and allows MITM attacks.

Disable default allowing the testing of connections in UI, API and CLI(#32052)

For security reasons, the test connection functionality is disabled by default across Airflow UI, API and CLI. The availability of the functionality can be controlled by the test_connection flag in the core section of the Airflow configuration (airflow.cfg). It can also be controlled by the environment variable AIRFLOW__CORE__TEST_CONNECTION.

The following values are accepted for this config param:

1. Disabled: Disables the test connection functionality and disables the Test Connection button in the UI.

This is also the default value set in the Airflow configuration. 2. Enabled: Enables the test connection functionality and activates the Test Connection button in the UI.

3. Hidden: Disables the test connection functionality and hides the Test Connection button in UI.
