# 1.0.0-M2.1

## Highlights

Significant changes for views being used within nd4j and samediff via the create\_view op allow for users to directly leverage views in combination with graph operations reducing allocations and allowing for increased performance.

Cuda 11.4 and 11.6 added. Add nd4j-cuda-11.4 and nd4j-cuda-11.6 to your dependencies.

New Onnx ops support added (<https://github.com/eclipse/deeplearning4j/pull/9663>):
