## 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).

- Fix /readyz to return error immediately after a shutdown is initiated, before the --shutdown-delay-duration has elapsed. ([#88911](https://github.com/kubernetes/kubernetes/pull/88911), [@tkashem](https://github.com/tkashem)) [SIG API Machinery]

    not reload checkpoints for evaluation.
*   `RunConfig` now sets device_filters to restrict how workers and PS can
    communicate. This can speed up training and ensure clean shutdowns in some
    situations. But if you have jobs that require communication between workers,
    you will have to set custom session_options in your `RunConfig`.
