### Deprecation

  It comes with an API change, a new delete option `ignoreStoreReadErrorWithClusterBreakingPotential` has
  been introduced, it is not set by default, this maintains backward compatibility.
  In order to perform an unsafe deletion of a corrupt resource, the user must enable the option for the delete

  Having appropriate QueueingHintFn contributes to reducing useless retries and thus improves the overall scheduler's performance.
  
  **How can I migrate?**
  
  For backward compatibility, nil `QueueingHintFn` is treated as always returning QueueAfterBackoff. 
  So, if you want to just keep the existing behavior, you can register `ClusterEventWithHint` with no `QueueingHintFn` in it. 

    * Add metrics `*_admission_latencies_milliseconds` and `*_admission_latencies_milliseconds_summary` for backward compatible, but will be removed in a future release.

imaginary_lit = (decimal_digits | int_lit | float_lit) "i" .

<p>
For backward compatibility, an imaginary literal's integer part consisting
entirely of decimal digits (and possibly underscores) is considered a decimal
integer, even if it starts with a leading <code>0</code>.

* For Deployment, ReplicaSet, and DaemonSet, selectors are now immutable when updating via the new `apps/v1beta2` API. For backward compatibility, selectors can still be changed when updating via `apps/v1beta1` or `extensions/v1beta1`.

- Dropped the additional rule requirement (cronjobs/finalizers) for roles
  using kubectl create cronjobs to ensure backward compatibility. ([#124883](https://github.com/kubernetes/kubernetes/pull/124883), [@ardaguclu](https://github.com/ardaguclu))
