"Please update your config before Apache Airflow 3.0"

./airflow2.3/lib/python3.8/site-packages/airflow/configuration.py:412:
FutureWarning: The 'log_filename_template' setting in [logging] has the old default value of '{{ ti.dag_id }}/{{ ti.task_id }}/{{ ts }}/{{ try_number }}.log'. This value has been changed to 'dag_id={{ ti.dag_id }}/run_id={{ ti.run_id }}/task_id={{ ti.task_id }}/{% if ti.map_index >= 0 %}map_index={{ ti.map_index }}/{% endif %}attempt={{ try_number }}.log' in the running config, but please update your config before Apache Airflow 3.0.

What is going to change?
What happens if I don't?

Format defined in [logging] log_filename_template will be ignored and I guess something bad happen. Nobody know when or if Airflow 3.0 released and which additional changes happen.

Perfect... that's my answer! Thanks also for the pointers to the relase notes. Don't know why I didn't think of that.

So it is optional and can be configured.... differently.

Now, is there a way to suppress the warning?

I you happy with new format, for example how it looks like

You just need to remove your current value from [logging] log_filename_template

Otherwise you should replace to something other then {{ ti.dag_id }}/{{ ti.task_id }}/{{ ts }}/{{ try_number }}.log
