+## Version 21.12.1 🔷
+
+_Current LTS version_
+

+- [#2355](https://github.com/sanic-org/sanic/pull/2355) Add config.update support for all config values

+    - *BREAKING CHANGE*: If you were manually routing signals there is a breaking change. The signal router's `get` is no longer 100% determinative. There is now an additional step to loop thru the returned signals for proper matching on the requirements. If signals are being dispatched using `app.dispatch` or `bp.dispatch`, there is no change.

+- [#2313](https://github.com/sanic-org/sanic/pull/2313) Support additional config implementation use case
+- [#2321](https://github.com/sanic-org/sanic/pull/2321) Refactor environment variable hydration logic

+
+### Deprecations and Removals
+- [#2306](https://github.com/sanic-org/sanic/pull/2306) Removal of deprecated items
+    - `Sanic` and `Blueprint` may no longer have arbitrary properties attached to them
+    - `Sanic` and `Blueprint` forced to have compliant names
+        - alphanumeric + `_` + `-`
+        - must start with letter or `_`
+    - `load_env` keyword argument of `Sanic`
+    - `sanic.exceptions.abort`
+    - `sanic.views.CompositionView`
+    - `sanic.response.StreamingHTTPResponse`

+    - 🚨 *BREAKING CHANGE*: The old `sanic.worker.GunicornWorker` has been **removed**. To run Sanic with `gunicorn`, you should use it thru `uvicorn` [as described in their docs](https://www.uvicorn.org/#running-with-gunicorn).
+    - 🧁 *SIDE EFFECT*: Named background tasks are now supported, even in Python 3.7
+- [#2357](https://github.com/sanic-org/sanic/pull/2357) Parse `Authorization` header as `Request.credentials`
+- [#2361](https://github.com/sanic-org/sanic/pull/2361) Add config option to skip `Touchup` step in application startup

+### 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).
