# `compute_XY` enables PTX embedding in addition to SASS. PTX
# is forward compatible beyond the current compute capability major
# release while SASS is only forward compatible inside the current
# major release. Example: sm_80 kernels can run on sm_89 GPUs but
# not on sm_90 GPUs. compute_80 kernels though can also run on sm_90 GPUs.

    support. Going forward, we will stop testing on Mac GPU systems. We continue
    to welcome patches that maintain Mac GPU support, and we will try to keep
    the Mac GPU build working.

## Changes to contrib APIs

*   The behavior of RNNCells is now stricter due to the transition towards
    making RNNCells act more like Keras layers.
