### Feature

- A new client side metric `rest_client_request_retries_total` has been added that tracks the number of retries sent to the server, partitioned by status code, verb and host ([#108396](https://github.com/kubernetes/kubernetes/pull/108396), [@tkashem](https://github.com/tkashem))

- The scheduler retries gated Pods more appropriately, giving them a backoff penalty too. ([#126029](https://github.com/kubernetes/kubernetes/pull/126029), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling]

                A `Lifespan` context manager handler. This replaces `startup` and
                `shutdown` functions with a single context manager.

                [FastAPI docs for `lifespan`](https://fastapi.tiangolo.com/advanced/events/).

### Feature

- A defaultpreemption plugin is registered and enabled in scheduler which replaces the legacy hard-coded Pod preemption logic. ([#92049](https://github.com/kubernetes/kubernetes/pull/92049), [@Huang-Wei](https://github.com/Huang-Wei)) [SIG Scheduling and Testing]

  - If all QueueingHintFn return QueueSkip, it puts this pod back to the unschedulable pod pool
  
  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. 

- Promoted `generateName` retries to beta, and made the `NameGenerationRetries` feature gate
  enabled by default.
