# Version 0.4.0¶

## What’s new in 0.4.0¶

• New operator to automate inference with the newly introduced MONAI Bundle

### MONAI Bundle Inference Operator¶

The new operator, MONAI Bundle Inference Operator, is intended to automate the inference with a MONAI Bundle in TorchScript with the following functionalities:

• Parse the model metadata and extra configuration data in the TorchScript file

• Instanciate MONAI transforms and inferer objects per bundle configuration data

• Convert input/output of the operator to and from model network input

• Support named model and can be used in a multi-model application

The example spleen segmentation application was accordingly updated to demonstrate the use of this new operator with the newly published Spleen CT Segmentation Bundle.

More details are in the tutorial.
