PropertyChangeRecord from 0.18.0.toObservableList and toObservableMap, better typed versions of toObservable.Fix generic type error that occurs when using ChangeNotifier with a subclass of ChangeRecord. Previously, calling notifyChanges() on class Foo with ChangeNotifier<CustomChangeRecord> {} would throw a type error. Now, the changes stream emits a custom ChangeRecords class that implements the List interface. This change is backwards compatible.
Support Dart 2 stable.
Bump and widen dev dependencies on build packages.
Update implementations of the cast() and the deprecated retype() methods.
retype() method on List and Map is deprecated and will be removed.cast() method should do what the retype() method did.Added ObservableList.castFrom, similar to List.castFrom.
Changed ObservableList's cast and retype function to create a forwarding instance of ObservableList instead of an instance of List.
Added ObservableMap.castFrom, similar to Map.castFrom.
Fixed a bug where ObservableMap's cast and retype function would create a new empty instance instead of a forwarding instance.
UnimplementedError.toObservable(deep: false) to be shallow again.Maps, for better compatibility with Dart 2.toObservable().ObservableList.from() to take Iterable, not Iterable<T>. This matches List.from() and avoids some unnecessary cast failures.Version 0.21.0 reverts to version 0.17.0+1 with fixes to support Dart 2. Versions 0.18, 0.19, and 0.20 were not used by the package authors and effectively unsupported. This resolves the fork that happened at version 0.18 and development can now be supported by the authors.

PropertyChangeMixin, which does not work in dart2jsThis is a larger change with a goal of no runtime changes for current customers, but in the future Observable will become a very lightweight interface, i.e.:
abstract class Observable<C extends ChangeRecord> { Stream<List<C>> get changes; }
