        tf.math.invert_permutation.
    *   Add `tf.math.sobol_sample` op.
    *   Add `tf.math.xlog1py`.
    *   Add `tf.math.special.{dawsn,expi,fresnel_cos,fresnel_sin,spence}`.
    *   Add a Modified Discrete Cosine Transform (MDCT) and its inverse to
        `tf.signal`.
*   TPU Enhancements:
    *   Refactor `TpuClusterResolver` to move shared logic to a separate pip
        package.
