 * Added support for "frozen objects" - these are objects, queries, lists, or Realms that have been "frozen" at a specific version. All frozen objects can be accessed and queried as normal, but attempting to mutate them or add change listeners will throw an exception. `Realm`, `RealmObject`, `RealmList`, and `RealmResults` now have a method `freeze()` which returns an immutable version of the object, as well as an `isFrozen` property which can be used to check whether an object is frozen. ([#56](https://github.com/realm/realm-dart/issues/56))
 * You can now set a realm property of type `T` to any object `o` where `o is T`. Previously it was required that `o.runtimeType == T`. ([#904](https://github.com/realm/realm-dart/issues/904))
 * Performance of indexOf on realm lists has been improved. It now uses realm-core instead of the generic version from ListMixin. ([#911](https://github.com/realm/realm-dart/pull/911)).
-* Added support for migrations for local Realms. You can now construct a configuration with a migration callback that will be invoked if the schema version of the file on disk is lower than the schema version supplied by the callback. (Issue [#70](https://github.com/realm/realm-dart/issues/70))

 * Fixed an issue that would cause passwords sent to the server (e.g. `Credentials.EmailPassword` or `EmailPasswordAuthProvider.registerUser`) to contain an extra empty byte at the end. (PR [#918](https://github.com/realm/realm-dart/pull/918))
+* Added support for realm list of nullable primitive types, ie. `RealmList<int?>`. ([#163](https://github.com/realm/realm-dart/issues/163))
