The documentation for each of these specifies the guarantees it
makes concerning synchronization.

Other packages that provide synchronization abstractions
should document the guarantees they make too.

// len(s) == 0, an empty slice is returned. Every element of the returned slice is
// non-empty. Unlike [SplitFunc], leading and trailing runs of code points
// satisfying f(c) are discarded.

// FieldsFunc makes no guarantees about the order in which it calls f(c)

    *   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.
    *   Replace tf.GraphKeys.VARIABLES with `tf.GraphKeys.GLOBAL_VARIABLES`.
