Keep in mind:

- If you’re adding a dependency with OS mentioned in an artifact name (`darwin`, `mac`, `osx`, `linux`, `windows`), remember to add them to 
  `implicitDependencies` configuration or update `resolveDependencies` task if needed. `resolveDependencies` should resolve all dependencies

## Deprecations

*   TensorFlow 1.1.0 will be the last time we release a binary with Mac GPU
    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.
