yuqian90 opened a new pull request #7331: [AIRFLOW-6657] Deprecate branch operator URL: https://github.com/apache/airflow/pull/7331 Everything that can be done by deriving from ``BaseBranchOperator`` can also be done using ``BranchPythonOperator`` with more concise and readable code. E.g. ``LatestOnlyOperator`` can be implemented from ``BranchPythonOperator`` easily. The test tasks in ``test_branch_operator.py`` are also better implemented using ``BranchPythonOperator`` like the ones in ``tests/operators/test_python.py`` The changes in this PR to ``LatestOnlyOperator`` does not require additional testing because there's already a ``test_latest_only_operator.py`` that works fine after the change. --- Issue link: WILL BE INSERTED BY [boring-cyborg](https://github.com/kaxil/boring-cyborg) Make sure to mark the boxes below before creating PR: [x] - [ ] Description above provides context of the change - [ ] Commit message/PR title starts with `[AIRFLOW-NNNN]`.
