scale clients have been modified to accept `context.Context` as a first argument. Signatures of Create, Update, and Patch methods have been updated to accept CreateOptions, UpdateOptions and PatchOptions respectively. Signatures of Delete and DeleteCollection methods now accept DeleteOptions by value instead of by reference. Generated clientsets with the previous interface have been added in new "deprecated" packages to allow incremental migration to the new APIs. The deprecated packages will be removed...

### API Machinery

* The Namespace API object no longer supports the deletecollection operation. ([#46407](https://github.com/kubernetes/kubernetes/pull/46407), [@liggitt](https://github.com/liggitt))

- Kube-apiserver: bugfix DeleteCollection API fails if request body is non-empty ([#113967](https://github.com/kubernetes/kubernetes/pull/113967), [@sxllwx](https://github.com/sxllwx)) [SIG API Machinery]

  abstract ImmutableCollection<E> delegateCollection();

  @Override
  public boolean contains(@CheckForNull Object target) {
    // The collection's contains() is at least as fast as ImmutableList's
    // and is often faster.
    return delegateCollection().contains(target);
  }

  @Override
  public int size() {
    return delegateCollection().size();
  }

  @Override

  abstract ImmutableCollection<E> delegateCollection();

  @Override
  public boolean contains(@CheckForNull Object target) {
    // The collection's contains() is at least as fast as ImmutableList's
    // and is often faster.
    return delegateCollection().contains(target);
  }

  @Override
  public int size() {
    return delegateCollection().size();
  }

  @Override

    super(backingSet, backingList);
  }

  @Override
  ImmutableSortedSet<E> delegateCollection() {
    return (ImmutableSortedSet<E>) super.delegateCollection();
  }

  @Override
  public Comparator<? super E> comparator() {
    return delegateCollection().comparator();
  }

  // Override indexOf() and lastIndexOf() to be O(log N) instead of O(N).

- Kube-apiserver: DELETECOLLECTION API requests are now recorded in metrics with the correct verb. ([#113133](https://github.com/kubernetes/kubernetes/pull/113133), [@sxllwx](https://github.com/sxllwx)) [SIG API Machinery]

- Fixed a bug where dry-run is not honored for pod/eviction sub-resource. ([#76969](https://github.com/kubernetes/kubernetes/pull/76969), [@apelisse](https://github.com/apelisse))

- DeleteOptions parameters for deletecollection endpoints are now published in the OpenAPI spec. ([#77843](https://github.com/kubernetes/kubernetes/pull/77843), [@roycaihw](https://github.com/roycaihw))

- Fixed the regression that introduced 34s timeout for DELETECOLLECTION calls ([#115341](https://github.com/kubernetes/kubernetes/pull/115341), [@tkashem](https://github.com/tkashem))
- Fixed two regressions introduced by the `PodDisruptionConditions` feature (on by default in 1.26):
