After you have tests, then you can upgrade the **FastAPI** version to a more recent one, and make sure that all your code is working correctly by running your tests.

If everything is working, or after you make the necessary changes, and all your tests are passing, then you can pin your `fastapi` to that new recent version.

## About Starlette

You shouldn't pin the version of `starlette`.

	// setProfLabel operations, not just the most recent one. This
	// is important because profBuf.read will observe different
	// labels set by different setProfLabel operations on
	// different goroutines, so it needs to synchronize with all
	// of them (this wouldn't be an issue if we could synchronize
	// on &getg().labels since we would synchronize with each
	// most-recent labels write separately.)
