#### Security
* Features:

  * Permission to use a PodSecurityPolicy can now be granted within a single namespace by allowing the use verb on the podsecuritypolicies resource within the namespace. ([#42360](https://github.com/kubernetes/kubernetes/pull/42360), [@liggitt](https://github.com/liggitt))

   * it be through separate factory instances or through multiple calls to the same factory,
   * attempting to acquire multiple locks with the same Enum value (within the same thread) will
   * result in an IllegalStateException regardless of the factory's policy. For example:
   *
   * {@snippet :
   * CycleDetectingLockFactory.WithExplicitOrdering<MyLockOrder> factory1 =

            // Ensure atomic cleanup of all resources
            synchronized (this) {
                // Double-check usage count within synchronized block
                if (this.usageCount.get() != 0) {
                    return; // Another thread acquired the session
                }

   * higher value than you need can waste space and time, and a significantly lower value can lead
   * to thread contention. But overestimates and underestimates within an order of magnitude do not
   * usually have much noticeable impact. A value of one permits only one thread to modify the cache
   * at a time, but since read operations and cache loading computations can proceed concurrently,
