 * Add `WatchFilePattern` transform, which can be used as a side input to the RunInference PTransfrom to watch for model updates using a file pattern. ([#24042](https://github.com/apache/beam/issues/24042))
 * Add support for loading TorchScript models with `PytorchModelHandler`. The TorchScript model path can be
   passed to PytorchModelHandler using `torch_script_model_path=<path_to_model>`. ([#25321](https://github.com/apache/beam/pull/25321))
