- Fix /readyz to return error immediately after a shutdown is initiated, before the --shutdown-delay-duration has elapsed. ([#88953](https://github.com/kubernetes/kubernetes/pull/88953), [@tkashem](https://github.com/tkashem)) [SIG API Machinery]

## 0.93.0 (2023-03-07)

### Features

* ✨ Add support for `lifespan` async context managers (superseding `startup` and `shutdown` events). Initial PR [#2944](https://github.com/tiangolo/fastapi/pull/2944) by [@uSpike](https://github.com/uSpike).

Now, instead of using independent `startup` and `shutdown` events, you can define that logic in a single function with `yield` decorated with `@asynccontextmanager` (an async context manager).
