This release replaces the underlying HTTP client used on the TestClient (requests ➡️ httpx), and as those clients differ a bit on their API, your test suite will likely break. To make the migration smoother, you can use the bump-testclient tool.

Changed

• Replace requests with httpx in TestClient #1376.

Added

• Add WebSocketException and support for WebSocket exception handlers #1263.
• Add middleware parameter to Mount class #1649.
• Officially support Python 3.11 #1863.
• Implement __repr__ for route classes #1864.

Fixed

• Fix bug on which BackgroundTasks were cancelled when using BaseHTTPMiddleware and client disconnected #1715.
