0.22.1+5

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.

0.22.1+3

Update implementations of the cast() and the deprecated retype() methods.

• The retype() method on List and Map is deprecated and will be removed.
• The cast() method should do what the retype() method did.

0.22.1+2

Widen dependency on the quiver package.

0.22.1+1

Fixes for Dart2 runtime type errors.

0.22.1

0.22.1

• 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.

0.22.0

0.22.0

• 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.

0.21.3

• Support Dart 2 collection methods where previously threw UnimplementedError.

0.21.2

• Fix toObservable(deep: false) to be shallow again.
• Remove use of Maps, for better compatibility with Dart 2.

Breaking Changes

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.

Reverted Changes

(From 0.20.1)

• Revert add Observable<List|Set|Map>.unmodifiable for immutable collections
• Revert add Observable<List|Set|Map>.EMPTY for empty immutable collections
  • This can be used as an optimization for libraries that always need to return
    an observable collection, but don't want to allocate a new instance to
    represent an empty immutable.

(From 0.20.0)

• Revert add ObservableSet, SetChangeRecord, and SetDiffer

(From 0.19.0)

• Revert refactor and deprecate ObservableMap-specific API
  • ObservableMap no longer emits #keys and #values change records
  • ObservableMap.spy is deprecated, becomes .delegate instead
• Revert Potentially breaking: ObservableMap may no longer be extended

Revert considered deprecated to be notified of length changes.

(From 0.18.0)

• Revert refactor and deprecate ObservableList-specific API
  • ObservableList.applyChangeRecords
  • ObservableList.calculateChangeRecords
  • ObservableList.withLength
  • ObservableList.deliverListChanges
  • ObservableList.discardListChanges
  • ObservableList.hasListChanges
  • ObservableList.listChanges
  • ObservableList.notifyListChange
• Revert potentially breaking: ObservableList may no longer be extended

Revert considered deprecated to be notified of length, isEmpty and
isNotEmpty PropertyChangeRecords on ObservableList
