# Developed on main, but applied on Airflow 2.4.3 so there were minor differences that failed the patch.
# - setup.cfg isn't shipped so had to filter that from patch 278fe3f4e8d852c11cdc2e0746ac676d549ccbac
# - Removed " -> list[str]" from patch 70682f45131f640f26a17b6c381e1c874cbad8f0 since that isn't specified in Airflow 2.4.3
# - Fixed the line count in 70682f45131f640f26a17b6c381e1c874cbad8f0 because ...
# - "     :rtype: list[unicode]" is specified in Airflow 2.4.3 but not in main, so had to add that back into patch 70682f45131f640f26a17b6c381e1c874cbad8f0
