airflow3-removal (AIR302)

Derived from the Airflow linter.

Fix is sometimes available.

This rule is unstable and in preview. The --preview flag is required for use.

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 to be maintained 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)
