CHANGELOG.md

@@ -67,6 +67,9 @@ So your change should look like:
   `obj.pos.x += 1` work again (#1109) - @ErikGXDev
 - Fixed `scale`, `skew`, and `rotate` component transforms not being applied on
   the initial `GameObjRaw.use()` call (e.g. `obj.use(scale(2))`) - @mflerackers
+- Fixed `AreaComp.area.scale` not being set properly and restored support for
+  `Vec2` property mutations on `scale` and `offset` (#1121) - @amyspark-ng,
+  @imaginarny
 - Fixed `isKeyDown` and `isButtonDown` getting stuck on game loosing focus
