* Add direct serializer ([#26251](https://github.com/kubernetes/kubernetes/pull/26251), [@caesarxuchao](https://github.com/caesarxuchao))
* Add a NodeCondition "NetworkUnavailable" to prevent scheduling onto a node until the routes have been created  ([#26415](https://github.com/kubernetes/kubernetes/pull/26415), [@wojtek-t](https://github.com/wojtek-t))

Ama dökümantasyon eksikti. Sonra APISpec geliştirildi.

Birçok framework için bir eklentidir (Starlette için de bir eklenti vardır).

Çalışma şekli: Her bir route’u işleyen fonksiyonun docstring’i içine YAML formatında şema tanımı yazarsınız.

Ve OpenAPI şemaları üretir.

Flask, Starlette, Responder vb. için çalışma şekli böyledir.

- One new field "InternalTrafficPolicy" in Service is added.
  It specifies if the cluster internal traffic should be routed to all endpoints or node-local endpoints only.
  "Cluster" routes internal traffic to a Service to all endpoints.
  "Local" routes traffic to node-local endpoints only, and traffic is dropped if no node-local endpoints are ready.

                openStateStartTime.set(0);
            }

            if (newState == State.OPEN) {
                openStateStartTime.set(System.currentTimeMillis());
            }

            // Reset counters based on transition
            switch (newState) {
            case CLOSED:
                failureCount.set(0);
                successCount.set(0);
                halfOpenAttempts.set(0);
                break;

The dependency injection system requires pre-registration of the dependencies and the dependencies are solved based on the declared types. So, it's not possible to declare more than one "component" that provides a certain type.

   * <p>Usage example:
   *
   * {@snippet :
   * ListenableFuture<Integer> fetchCounterFuture = ...;
   *
   * // Falling back to a zero counter in case an exception happens when
   * // processing the RPC to fetch counters.
   * ListenableFuture<Integer> faultTolerantFuture = Futures.catching(
   *     fetchCounterFuture, FetchException.class, x -> 0, directExecutor());
   * }
