 ## New Features / Improvements
 
-* X feature added (Java/Python) ([#X](https://github.com/apache/beam/issues/X)).
 * The Python SDK now type checks `collections.abc.Collections` types properly. Some type hints that were erroneously allowed by the SDK may now fail. ([#29272](https://github.com/apache/beam/pull/29272))
 * Running multi-language pipelines locally no longer requires Docker.
   Instead, the same (generally auto-started) subprocess used to perform the
   expansion can also be used as the cross-language worker.
-* Framework for adding Error Handlers to composite transforms added in Java ([#29164](https://github.com/apache/beam/pull/29164))
