## Summary `include_examples` was silently removed from `DagBag.__init__` and `DagBag.collect_dags()` in a minor version bump (3.1.8 -> 3.3.0), breaking any code that constructs `DagBag` directly with this argument — a common pattern in custom scripts and DAG validation tests — with a `TypeError: __init__() got an unexpected keyword argument 'include_examples'`. This wasn't mentioned in the 3.3.0 release notes and violates semver expectations for a minor release. ## Root Cause Example DAGs are now loaded via the DAG bundle system (`DagBundlesManager`) instead of `DagBag` scanning `airflow.example_dags` directly. That architectural change is reasonable on its own, but the `include_examples` parameter was removed outright instead of being deprecated, so any caller passing it — whether `True` or `False` — hits a hard crash instead of a warning. ## Fix Restores `include_examples` to `DagBag.__init__` and `DagBag.collect_dags()`, along with `BundleDagBag`'s guard against `include_examples=True`. When the parameter is omitted (the common case), behavior is unchanged and no warning is emitted. When passed explicitly, it still works as it did pre-3.3.0 but now emits a `DeprecationWarning` pointing callers to the new DAG bundle system instead of crashing. Added `TestDagBagIncludeExamples` in `test_dagbag.py` covering the omitted, explicit-True, explicit-False, and `BundleDagBag` cases.
