Tout est basé sur les déclarations de **types Python** standard (grâce à Pydantic). Aucune nouvelle syntaxe à apprendre. Juste du Python moderne standard.

## Version 5.0.0-alpha.5

_2022-02-21_

 *  Fix: Don't include [Assertk][assertk] in OkHttp's production dependencies. This regression was
    introduced in the 5.0.0-alpha.4 release.
 *  Fix: Don't ask `Dns` implementations to resolve strings that are already IP addresses.
 *  Fix: Change fast fallback to race TCP handshakes only. To avoid wasted work, OkHttp will not

* Fixed missing error checking that could cause kubelet to crash in a race condition. ([#60962](https://github.com/kubernetes/kubernetes/pull/60962), [@technicianted](https://github.com/technicianted))
* Bump Heapster to v1.5.2 ([#61396](https://github.com/kubernetes/kubernetes/pull/61396), [@kawych](https://github.com/kawych))

            value = t;

            // In the very unlikely event that nanos is 0, set it to 1;

    reuse pod names (they use generate-name).
  * User-written controllers that reuse names of pod objects should evaluate this change.
  * When deleting an object with `kubectl delete ... --grace-period=0`, the client will
    begin a graceful deletion and wait until the resource is fully deleted.  To force
    deletion immediately, use the `--force` flag. This prevents users from accidentally
