Ici, le paramètre `q` sera optionnel, et aura `None` comme valeur par défaut.

/// check | "Remarque"

On peut voir que **FastAPI** est capable de détecter que le paramètre de chemin `item_id` est un paramètre de chemin et que `q` n'en est pas un, c'est donc un paramètre de requête.

///

/// note

**FastAPI** saura que `q` est optionnel grâce au `=None`.

  // whose value of the label with key topologyKey matches that of any node on which any of the
  // selected pods is running.
  // Empty topologyKey is not allowed.
  optional string topologyKey = 3;

  // A label query over the set of namespaces that the term applies to.
  // The term is applied to the union of the namespaces selected by this field
  // and the ones listed in the namespaces field.

### Bug or Regression

- Fix Azure file share not deleted issue when the namespace is deleted ([#97417](https://github.com/kubernetes/kubernetes/pull/97417), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider and Storage]

      if (createNewEntry) {
        try {
          // Synchronizes on the entry to allow failing fast when a recursive load is
          // detected. This may be circumvented when an entry is copied, but will fail fast most
          // of the time.
          synchronized (e) {
            return loadSync(key, hash, loadingValueReference, loader);
          }

- Fix: the volume is not detached after the pod and PVC objects are deleted ([#117339](https://github.com/kubernetes/kubernetes/pull/117339), [@cvvz](https://github.com/cvvz)) [SIG Storage]

forward that traffic to the Waypoint proxy **after** applying any `TRANSPORT` layer policies (i.e. `Authorization`s). Thus, if the destination workload has at least the equivalent of a `STRICT` `PeerAuthentication`, unauthenticated traffic will be rejected before it reaches the Waypoint proxy. If the effective policy is `PERMISSIVE` (the default), the ztunnel will open a vanilla TLS HBONE tunnel (NOTE: this is not mTLS) to the Waypoint proxy and forward the traffic over that connection without presenting...

- Finalizer Protection for Service LoadBalancers (ServiceLoadBalancerFinalizer) has been added as an Alpha feature, which is disabled by default. This feature ensures the Service resource is not fully deleted until the correlating load balancer resources are deleted. ([#78262](https://github.com/kubernetes/kubernetes/pull/78262), [@MrHohn](https://github.com/MrHohn))
