+Removed ``conf`` from the Task template context
+
+The ``conf`` variable, which provided access to the full Airflow configuration
(``airflow.cfg``), has been
+removed from the Task (Jinja2) template context for security and simplicity.
If you
+need specific configuration values in your tasks, retrieve them explicitly in
your DAG or task code
+using the ``airflow.configuration.conf`` module.
+
+For users retrieving the webserver URL (e.g., to include log links in task or
callbacks), one of the
+most common use-case, use the ``ti.log_url`` property available in the
``TaskInstance`` context instead.
+
+Example:
+
+.. code-block:: python
+
+ from airflow.providers.standard.operators.python import PythonOperator
+ from airflow.providers.smtp.notifications.smtp import SmtpNotifier
+
+
+ def my_task_callable(ti):
+ log_url = ti.log_url # Retrieve the log URL
+
+
+ with DAG("my_dag", schedule_interval="@daily") as dag:
+ task = PythonOperator(
+ task_id="my_task",
+ python_callable=my_task_callable,
+ on_failure_callback=SmtpNotifier(
+ from_email="[email protected]",
+ to="[email protected]",
+ subject="Task {{ ti.task_id }} failed",
+ html_content="Task <b>{{ ti.task_id }}</b> failed. Log URL: {{
ti.log_url }}",
+ ),
+ )
