## 0.41.0

* Upgrade required Starlette to `0.12.9`, the new range is `>=0.12.9,<=0.12.9`.
    * Add `State` to FastAPI apps at `app.state`.
    * PR [#593](https://github.com/tiangolo/fastapi/pull/593).
* Improve handling of custom classes for `Request`s and `APIRoute`s.
    * This helps to more easily solve use cases like:

- Fixed a startup probe race condition that caused main containers to remain stuck in "Initializing" state when sidecar containers with startup probes failed initially but succeeded on restart in pods with restartPolicy=Never. ([#134801](https://github.com/kubernetes/kubernetes/pull/134801), [@yuanwang04](https://github.com/yuanwang04)) [SIG Node and Testing]...

### Bug or Regression

- Fix missing delete events on informer re-lists to ensure all delete events are correctly emitted and using the latest known object state, so that all event handlers and stores always reflect the actual apiserver state as best as possible ([#115900](https://github.com/kubernetes/kubernetes/pull/115900), [@odinuge](https://github.com/odinuge)) [SIG API Machinery]

  - The `export` query parameter for list API calls, deprecated since v1.14, will be removed in v1.18.
  - The `series.state` field in the events.k8s.io/v1beta1 Event API is deprecated and will be removed in v1.18 ([#75987](https://github.com/kubernetes/kubernetes/pull/75987), [@yastij](https://github.com/yastij))

  `Why?' said the Caterpillar.

  Here was another puzzling question; and as Alice could not
think of any good reason, and as the Caterpillar seemed to be in
a VERY unpleasant state of mind, she turned away.

  `Come back!' the Caterpillar called after her.  `I've something
important to say!'

  This sounded promising, certainly:  Alice turned and came back
again.
