 * Both the unnecessary port specification (`:80`) and the absent trailing slash (`/`) cause URI to
 * bucket the two URLs separately. This harms URI's usefulness in collections. Any application that
 * stores information-per-URL will need to either canonicalize manually, or suffer unnecessary
 * redundancy for such URLs.

- Fixed a regression in default configurations, which enabled `PodDisruptionConditions`
  by default, that prevented the control plane's pod garbage collector from deleting
  pods that contained duplicated field keys (environmental variables with repeated keys or
  container ports). ([#121103](https://github.com/kubernetes/kubernetes/pull/121103), [@mimowo](https://github.com/mimowo))

* Finalizers are now honored on custom resources, and on other resources even when garbage collection is disabled via the apiserver flag `--enable-garbage-collector=false` ([#51469](https://github.com/kubernetes/kubernetes/pull/51469), [@ironcladlou](https://github.com/ironcladlou))
