+### Features
+- [#2378](https://github.com/sanic-org/sanic/pull/2378) Introduce HTTP/3 and autogeneration of TLS certificates in `DEBUG` mode
+    - 👶 *EARLY RELEASE FEATURE*: Serving Sanic over HTTP/3 is an early release feature. It does not yet fully cover the HTTP/3 spec, but instead aims for feature parity with Sanic's existing HTTP/1.1 server. Websockets, WebTransport, push responses are examples of some features not yet implemented.
+    - 📦 *EXTRA REQUIREMENT*: Not all HTTP clients are capable of interfacing with HTTP/3 servers. You may need to install a [HTTP/3 capable client](https://curl.se/docs/http3.html).
+    - 📦 *EXTRA REQUIREMENT*: In order to use TLS autogeneration, you must install either [mkcert](https://github.com/FiloSottile/mkcert) or [trustme](https://github.com/python-trio/trustme).
+- [#2416](https://github.com/sanic-org/sanic/pull/2416) Add message to `task.cancel`
+- [#2420](https://github.com/sanic-org/sanic/pull/2420) Add exception aliases for more consistent naming with standard HTTP response types (`BadRequest`, `MethodNotAllowed`, `RangeNotSatisfiable`)

+- [#2439](https://github.com/sanic-org/sanic/pull/2439) New API for reading form values with options: `Request.get_form` 
+- [#2447](https://github.com/sanic-org/sanic/pull/2447), [#2486](https://github.com/sanic-org/sanic/pull/2486) Improved API to support setting cache control headers
+- [#2453](https://github.com/sanic-org/sanic/pull/2453) Move verbosity filtering to logger
+- [#2475](https://github.com/sanic-org/sanic/pull/2475) Expose getter for current request using `Request.get_current()`
+
+### Bugfixes
+- [#2448](https://github.com/sanic-org/sanic/pull/2448) Fix to allow running with `pythonw.exe` or places where there is no `sys.stdout`
+- [#2451](https://github.com/sanic-org/sanic/pull/2451) Trigger `http.lifecycle.request` signal in ASGI mode
+- [#2455](https://github.com/sanic-org/sanic/pull/2455) Resolve typing of stacked route definitions
+- [#2463](https://github.com/sanic-org/sanic/pull/2463) Properly catch websocket CancelledError in websocket handler in Python 3.7
