 - Breaking changes
     * This marks the first release of using "transforms as operators". This allows transforms to be used in any operator expression, whereas the previous release required them to be on separate lines. For an example, please see: https://nvidia.github.io/MatX/basics/fusion.html. This also causes a breaking change with transform usage. Converting to the new format is as simple as moving the function parameters. For example: `matmul(C, A, B, stream);` becomes `(C = matmul(A,B)).run(stream);`.
