feature.
*   Full new features (e.g., a new op implementing a cutting-edge algorithm)
    typically will live in
    [tensorflow/addons](https://github.com/tensorflow/addons) to get some
    airtime before a decision is made regarding whether they are to be migrated
    to the core.
*   As every PR requires several CPU/GPU hours of CI testing, we discourage

    *   Add tf_api_version flag. If --define=tf_api_version=2 flag is passed in,
        then bazel will build TensorFlow API version 2.0. Note that TensorFlow
        2.0 is under active development and has no guarantees at this point.
    *   Add additional compression options to TfRecordWriter.
    *   Performance improvements for regex full match operations.
