### `shutdown` event

To add a function that should be run when the application is shutting down, declare it with the event `"shutdown"`:

{* ../../docs_src/events/tutorial002.py hl[6] *}

Here, the `shutdown` event handler function will write a text line `"Application shutdown"` to a file `log.txt`.

    @PreDestroy
    public void shutdown() {
        repositorySystemProvider.get().shutdown();
    }

### 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).
