+# changelog
+
+This file contains highlights of what changes on each version of the observe
+package.
+
+#### Pub version 0.10.0-dev
+  * package:observe no longer declares @MirrorsUsed. The package uses mirrors
+    for development time, but assumes frameworks (like polymer) and apps that
+    use it directly will either generate code that replaces the use of mirrors,
+    or add the @MirrorsUsed declaration themselves. For convinience, you can
+    import 'package:observe/mirrors_used.dart', and that will add a @MirrorsUsed
+    annotation that preserves properties and classes labeled with @reflectable
+    and properties labeled with @observable.
