## Breaking Changes to the API

*   `AdjustContrast` kernel deprecated, new kernel `AdjustContrastv2` takes and
    outputs float only. `adjust_contrast` now takes all data types.
*   `adjust_brightness`'s `delta` argument is now always assumed to be in
    `[0,1]` (as is the norm for images in floating point formats), independent
    of the data type of the input image.
