* Large refactor, improvement, and simplification of param extraction from *path operations*.
    * Fix/add support for list *query parameters* with list defaults. New documentation: [Query parameter list / multiple values with defaults](https://fastapi.tiangolo.com/tutorial/query-params-str-validations/#query-parameter-list-multiple-values-with-defaults).

- Fix non-recursive list returning "resource version too high" error when consistent list from cache is enabled ([#123674](https://github.com/kubernetes/kubernetes/pull/123674), [@serathius](https://github.com/serathius)) [SIG API Machinery]

- Kube-apiserver: `gzip` compression switched from level 4 to level 1 to improve large list call latencies in exchange for higher network bandwidth usage (10-50% higher). This increases the headroom before very large unpaged list calls exceed request timeout limits. ([#112299](https://github.com/kubernetes/kubernetes/pull/112299), [@shyamjvs](https://github.com/shyamjvs))

- The list of validated docker versions has changed. 1.11.1 and 1.12.1 have been removed. The current list is 1.13.1, 17.03, 17.06, 17.09, 18.06, 18.09. ([#72823](https://github.com/kubernetes/kubernetes/pull/72823), [#72831](https://github.com/kubernetes/kubernetes/pull/72831))
