* X behavior was changed ([#X](https://github.com/apache/beam/issues/X)).
* Yapf version upgraded to 0.43.0 for formatting (Python)
([#34801](https://github.com/apache/beam/pull/34801/)).
* Python: Added JupyterLab 4.x extension compatibility for enhanced notebook
integration ([#34495](https://github.com/apache/beam/pull/34495)).
+* Python: Argument abbreviation is no longer enabled within Beam. If you
previously abbreviated arguments (e.g. `--r` for `--runner`), you will now need
to specify the whole argument
([#34934](https://github.com/apache/beam/pull/34934)).
