-### 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
-- [#2264](https://github.com/sanic-org/sanic/pull/2264) Optional `uvloop` by configuration

-- [#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.

-- [#2309](https://github.com/sanic-org/sanic/pull/2309) Builtin signals changed to `Enum`

-    - `Sanic` and `Blueprint` forced to have compliant names
