### [`v0.93.0`](https://togithub.com/tiangolo/fastapi/releases/tag/0.93.0)
[Compare Source](https://togithub.com/tiangolo/fastapi/compare/0.92.0...0.93.0)
##### Features
- ✨ Add support for `lifespan` async context managers (superseding `startup` and `shutdown` events). Initial PR [#2944](https://togithub.com/tiangolo/fastapi/pull/2944) by [@uSpike](https://togithub.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).
For example:
```Python
from contextlib import asynccontextmanager
from fastapi import FastAPI
def fake_answer_to_everything_ml_model(x: float):
return x * 42
ml_models = {}
@asynccontextmanager
async def lifespan(app: FastAPI):
### Load the ML model
ml_models["answer_to_everything"] = fake_answer_to_everything_ml_model
yield
### Clean up the ML models and release the resources
ml_models.clear()
app = FastAPI(lifespan=lifespan)
@app.get("/predict")
async def predict(x: float):
result = ml_models["answer_to_everything"](x)
return {"result": result}
```
**Note**: This is the recommended way going forward, instead of using `startup` and `shutdown` events.
