+## Version 21.12.0
+
+### Features
+- [#2260](https://github.com/sanic-org/sanic/pull/2260) Allow early Blueprint registrations to still apply later added objects
+- [#2262](https://github.com/sanic-org/sanic/pull/2262) Noisy exceptions - force logging of all exceptions

+- [#2277](https://github.com/sanic-org/sanic/pull/2277) Change signal routing for increased consistency
+    - *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.

+- [#2291](https://github.com/sanic-org/sanic/pull/2291) Increase join concat performance

+- [#2302](https://github.com/sanic-org/sanic/pull/2302) Add route context at definition time
+- [#2304](https://github.com/sanic-org/sanic/pull/2304) Named tasks and new API for managing background tasks
+- [#2307](https://github.com/sanic-org/sanic/pull/2307) On app auto-reload, provide insight of changed files
+- [#2308](https://github.com/sanic-org/sanic/pull/2308) Auto extend application with [Sanic Extensions](https://sanicframework.org/en/plugins/sanic-ext/getting-started.html) if it is installed, and provide first class support for accessing the extensions
+- [#2309](https://github.com/sanic-org/sanic/pull/2309) Builtin signals changed to `Enum`
+- [#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
+- [#2327](https://github.com/sanic-org/sanic/pull/2327) Prevent sending multiple or mixed responses on a single request
+- [#2330](https://github.com/sanic-org/sanic/pull/2330) Custom type casting on environment variables
+- [#2332](https://github.com/sanic-org/sanic/pull/2332) Make all deprecation notices consistent
+- [#2335](https://github.com/sanic-org/sanic/pull/2335) Allow underscore to start instance names

+    - `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`
+        - *NOTE:* the `stream()` response method (where you pass a callable streaming function) has been deprecated and will be removed in v22.6. You should upgrade all streaming responses to the new style: https://sanicframework.org/en/guide/advanced/streaming.html#response-streaming
