airflow3-removal (AIR301)

Derived from the Airflow linter.

Fix is sometimes available.

What it does

Checks for uses of deprecated Airflow functions and values.

Why is this bad?

Airflow 3.0 removed various deprecated functions, members, and other values. Some have more modern replacements. Others are considered too niche and not worth continued maintenance in Airflow.

Example

from airflow.utils.dates import days_ago


yesterday = days_ago(today, 1)

Use instead:

from datetime import timedelta


yesterday = today - timedelta(days=1)
