# v1.18.0-alpha.4

[Documentation](https://docs.k8s.io)

## Important note about manual tag

Due to a [tagging bug in our Release Engineering tooling](https://github.com/kubernetes/release/issues/1080) during `v1.18.0-alpha.3`, we needed to push a manual tag (`v1.18.0-alpha.4`).

### Structured Logging in Kubelet

* Alpha list paging implementation ([#48921](https://github.com/kubernetes/kubernetes/pull/48921), [@smarterclayton](https://github.com/smarterclayton))
* add reconcile command to kubectl auth ([#51636](https://github.com/kubernetes/kubernetes/pull/51636), [@deads2k](https://github.com/deads2k))

    /**

     * The value is, e.g. true <br>
     * comment: logging
     * @return The value of found property. (NotNull: if not found, exception but basically no way)
     */
    String getLoggingSearchDocsEnabled();

    /**

     * The value is, e.g. true <br>
