- New flag `--show-hidden-metrics-for-version` in kubelet can be used to show all hidden metrics that deprecated in the previous minor release. ([#85282](https://github.com/kubernetes/kubernetes/pull/85282), [@serathius](https://github.com/serathius)) [SIG Node]

    *   Add `tf.keras.layers.AbstractRNNCell` as the preferred implementation
        for RNN cells in TF v2. User can use it to implement RNN cells with
        custom behavior.
    *   Keras training and validation curves are shown on the same plot when
        using the TensorBoard callback.
    *   Switched Keras `fit/evaluate/predict` execution to use only a single
        unified path by default unless eager execution has been explicitly
