The feature is disabled if HTTP2_READ_IDLE_TIMEOUT_SECONDS is set to 0. ([#96778](https://github.com/kubernetes/kubernetes/pull/96778), [@caesarxuchao](https://github.com/caesarxuchao))...

    *   `CategoryCrossing`: create new categorical features representing
        co-occurrences of previous categorical feature values
    *   `Hashing`: the hashing trick, for large-vocabulary categorical features
    *   `Discretization`: turn continuous numerical features into categorical
        features by binning their values
*   Improved **image preprocessing** layers: `CenterCrop`, `Rescaling`
