Before, you'd get an error like:
```
EXCEPTION: Cannot find a differ supporting object ‘[object Object]’ in [users in UsersCmp@2:14]
```
Now, you get:
```
EXCEPTION: Cannot find a differ supporting object ‘[object Object]’ of type 'Object'. Did you mean to bind ngFor to an Array? in [users in UsersCmp@2:14]
```
Add a check in `ReflectionCapabilities#interfaces` which determines if
the passed-in type implements a Lifecycle Interface but does not declare
that it does so.

Closes#6849
BREAKING CHANGE:
`OnPushObserve` was an experimental
feature for Dart and had
conceptual performance problems,
as setting up observables is slow.
Use `OnPush` instead.
BREAKING CHANGE:
In Dart we used to support injecting types with generics. As this feature is hard to implement with the upcoming codegen we are dropping it.
Merge cl/115454020 in G3 with this change.
Closes#7262
This resolves Duplicate Identifier issues seen by many users,
at the expense of more typings installation required in some
cases.
Removes the quickstart hack of placing all needed dependencies
typings files in our distribution. Removes dependencies on
nodejs from angular2/core.
Fixes#5973Fixes#5807Fixes#6266
Angular now depends on es6-promise and es6-collections
(and a handful of manual typings) rather than all of es6-shim.
Fixes#5242
We previously had an undocumented breaking change, this is now
documented in this commit.
Fixes#6817
BREAKING CHANGE:
Transitive typings are no longer included in the distribution.
You may need to install typings in your project using
http://github.com/typings/typings
Users now must rely on getting typings from:
- one of the peerDependencies, such as rxjs, which exposes
typings via the moduleResolution=node mechanism.
(see https://github.com/Microsoft/TypeScript/wiki/Typings-for-npm-packages)
This happens automatically.
- Using --target ES5 now requires manual installation of
es6-promise and es6-collections typings.
- Using some angular APIs may introduce a dependency on eg. nodejs
or jasmine, and those typings need manual installation as well.
Closes#6267
Now, using `ng.probe(element)` in the browser console returns
a DebugElement when in dev mode.
`ComponentFixture#debugElement` also returns a new DebugElement.
Breaking Change:
This is a breaking change for unit tests. The API for the DebugElement
has changed. Now, there is a DebugElement or DebugNode for every node
in the DOM, not only nodes with an ElementRef. `componentViewChildren` is
removed, and `childNodes` is a list of ElementNodes corresponding to every
child in the DOM. `query` no longer takes a scope parameter, since
the entire rendered DOM is included in the `childNodes`.
Before:
```
componentFixture.debugElement.componentViewChildren[0];
```
After
```
// Depending on the DOM structure of your component, the
// index may have changed or the first component child
// may be a sub-child.
componentFixture.debugElement.children[0];
```
Before:
```
debugElement.query(By.css('div'), Scope.all());
```
After:
```
debugElement.query(By.css('div'));
```
Before:
```
componentFixture.debugElement.elementRef;
```
After:
```
componentFixture.elementRef;
```
