  /// Thread safety:
  /// The iterator and timestamp fields should only be accessed while holding
  /// the block-cache-wide mu_ instance variable. The state variable should only

/// be used without recompilation in the widest range of TensorFlow versions.

/// The header is divided into sections, as follows:
///   1. Opaque plugin private data structures and wrappers for type safety;
///   2. Function tables for plugin functionality;
///   3. Versioning metadata;
///   4. Plugin registration API and the DSO entry point.

*   Extend `tf.contrib.distributions.bijector` API to handle some non-injective
    transforms.
*   Java:
    *   Generics (e.g., `Tensor<Integer>`) for improved type-safety (courtesy
        @andrewcmyers).
    *   Support for multi-dimensional string tensors.
    *   Support loading of custom operations (e.g. many in `tf.contrib`) on
        Linux and OS X
