<a name="4.0.0-rc.1"></a>
# [4.0.0-rc.1](https://github.com/angular/angular/compare/4.0.0-beta.8...4.0.0-rc.1) (2017-02-24)

We are excited to share 4.0.0-RC.1 with the community. This is a feature-complete pre-release of 4.0.0. Upgrade to get to know the new features to be released in 4.0.0, and to help us validate the release.

It’s important to note that this release has been tested extensively. All Angular applications within Google use the master branch of Angular, so every commit is tested and validated at scale prior to any release.

## We Need Your Help
Please give this RC a try and test it with your projects! We have spent a significant amount of time working to ensure that this release is backwards compatible and will work with your existing code, but you may have use cases we haven’t anticipated. If you are broken by this release, let us know so that we can look into it right away. We are also looking for feedback related to the ergonomics of any newly added APIs.

## What’s New

### View Engine
We’ve made changes under to hood to what AOT generated code looks like. These changes should reduce the size of the generated code for your components by more than half in some cases. Read the [Design Doc](https://docs.google.com/document/d/195L4WaDSoI_kkW094LlShH6gT3B7K1GZpSBnnLkQR-g/preview) for the View Engine updates.


### Enhanced `*ngIf` syntax
Our template binding syntax now supports a couple helpful changes. You can now use an if/else style syntax, and assign local variables such as when unrolling an observable.

```
<ng-template #loading>Loading...</ng-template>
<div *ngIf="userObservable | async; else loading; let user">
  {{ user.name }}
</div>
```


### Animation Package
We have pulled Animations into their own package. This means that if you don’t use Animations, this extra code will not end up in your production bundles. This also allows you to more easily find documentation and to take better advantage of autocompletion. If you do need animations, libraries like Material will automatically import the module (once you install it via NPM), or you can add it yourself to your main NgModule.


### TypeScript 2.1
We’ve updated Angular to a more recent version of TypeScript. This will improve the speed of `ngc` and you will get better type checking throughout your application.


### StrictNullChecks
Angular is now compliant with [TypeScript’s StrictNullChecks](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-2-0.html). This means that you can enable StrictNullChecks in your project, if desired.


### Universal
Universal, the project that allows developers to run Angular on a server, is now up to date with Angular again, and has been adopted by the Angular team. This release now includes the results of the work from the Universal team over the last few months. The majority of the Universal code is now in platform-server. To learn more about this change, take a look the new [`renderModuleFactory`](https://github.com/angular/angular/blob/56f232cdd70a352cb9151bc7cfe8981bc2710ea6/modules/%40angular/platform-server/src/utils.ts#L63-L72) method, or Rob Wormald’s [Demo Repository](https://github.com/robwormald/ng-universal-demo/). More documentation is forthcoming.


<a name="flat-es-modules-esm"></a><!-- legacy anchor link, keep it here -->
### Flat ES Modules (Flat ESM / FESM)
We now ship flattened versions of our modules ("rolled up" version of our code in the EcmaScript Module format, see [example file](https://github.com/angular/core-builds/blob/85cbe3f8d6107af033b0f8b56456c181cbcb5eb7/%40angular/core.js)). This format should help tree-shaking, help reduce the size of your generated bundles, and speed up build, transpilation, and loading in the browser in certain scenarios.


### ES2015 Builds
We now also ship our packages in the ES2015 Flat ESM format. This option is experimental and opt-in (configure your webpack to resolve ["es2015" property](https://github.com/angular/core-builds/blob/dc0c8d828a8bae6591d2b9c77974271481af818c/package.json#L7) in package.json over the regular ["module" property](https://github.com/angular/core-builds/blob/dc0c8d828a8bae6591d2b9c77974271481af818c/package.json#L6)).


## Known Issues

The following is a list of known issues that will be fixed in the next rcs.

- Source maps are missing in npm packages
- Generated bundles will be larger temporarily while we validate new code paths and remove old ones
- angular.io docs have not been updated to reflect API changes in 4.0
- legacy UMD bundles don't have correct RxJS mappings when running in ES5 mode without a module system


## Installing RC.1
We have two main ways to update. If you have an existing project, you should be able to run:

On Linux/Mac: `npm install @angular/{common,compiler,compiler-cli,core,forms,http,platform-browser,platform-browser-dynamic,platform-server,router,animations}@next --save`
On Windows: `npm install @angular/common@next @angular/compiler@next @angular/compiler-cli@next @angular/core@next @angular/forms@next @angular/http@next @angular/platform-browser@next @angular/platform-browser-dynamic@next @angular/platform-server@next @angular/router@next @angular/animations@next --save`


Then run whatever `ng serve` or `npm start` command you normally use, and everything should work.

*Please ensure that you are using Typescript v2.1.6 or higher.*

*If you rely on Animations* you’ll also need to install the animations package `@angular/animations` and import the new `BrowserAnimationsModule` from `@angular/platform-browser/animations` in your root NgModule. Without this, your code will compile and run, but animations won’t activate.
Imports from `@angular/core` were deprecated, use imports from the new package `import { trigger, state, style, transition, animate } from '@angular/animations';`.

## What's next?
We have [three more release candidates scheduled](https://github.com/angular/angular/blob/master/docs/RELEASE_SCHEDULE.md) before our planned GA the week of March 22. In the meantime we'll be looking for your feedback, fixing bugs and working on docs.

### Performance Improvements

* distribute smaller bundled code and include es2015 bundle ([de795ea](https://github.com/angular/angular/commit/de795ea))


### BREAKING CHANGES

* core: Because all lifecycle hooks are now interfaces the code that uses 'extends' keyword will no longer compile. Introduced by ([ee747f7](https://github.com/angular/angular/commit/ee747f7)).

  To migrate the code follow the example below:

  Before:
  ```
  @Component()
  class SomeComponent extends OnInit {}
  ```
  After:
  ```
  @Component()
  class SomeComponent implements OnInit {}
  ```

  Based on our research we don't expect anyone to be affected by this change.

* `RootRenderer` cannot be used any more, use `RendererFactoryV2` instead. Introduced by ([ccb636c](https://github.com/angular/angular/commit/ccb636c)).

  Note: `Renderer` can still be injected/used, but is deprecated.

Note: the 4.0.0-rc.0 release on npm accidentally omitted one bug fix, so we cut rc.1 instead. oops :-)

### DEPRECATIONS

* core: `KeyValueDifferFactory` and `IterableDifferFactory` no longer have `ChangeDetectorRef` as
  a parameter. It was not used and has been there for historical reasons. If you call
  `DifferFactory.create(...)` remove the `ChangeDetectorRef` argument. Introduced by ([#14311](https://github.com/angular/angular/pull/14311)).


### BREAKING CHANGES

* common: Classes that derive from `AsyncPipe` and override
`transform()` might not compile correctly. The much more common use of `async` pipe in
templates is unaffected. We expect no or little impact on apps from this change, file an issue if we break you. Introduced by ([#14367](https://github.com/angular/angular/issues/14367)) ([4da7925](https://github.com/angular/angular/commit/4da7925)).

  * Mitigation: Update derived classes of `AsyncPipe` that override `transform()` to include the type parameter overloads.

### Performance Improvements

* use abstract keyword where possible to decrease file size. ([#14112](https://github.com/angular/angular/issues/14112)) ([670b680](https://github.com/angular/angular/commit/670b680))

### BREAKING CHANGES

* common: A definition of `Iterable<T>` is now required to correctly compile
Angular applications. Support for `Iterable<T>` is not required at
runtime but a type definition `Iterable<T>` must be available.

`NgFor`, and now `NgForOf<T>`, already supports `Iterable<T>` at
runtime. With this change the type definition is updated to reflect
this support.

Migration:
- add "es2015.iterable.ts" to your tsconfig.json "libs" fields.

Part of #12398
* upgrade: Previously, `upgrade/static/downgradeInjectable` returned an array of the form:

```js
['dep1', 'dep2', ..., function factory(dep1, dep2, ...) { ... }]
```

Now it returns a function with an `$inject` property:

```js
factory.$inject = ['dep1', 'dep2', ...];
function factory(dep1, dep2, ...) { ... }
```

It shouldn't affect the behavior of apps, since both forms are equally suitable
to be used for registering AngularJS injectable services, but it is possible
that type-checking might fail or that current code breaks if it relies on the
returned value being an array.

### Features

* **build:** optionally build an ES2015 distro ([#13471](https://github.com/angular/angular/issues/13471)) ([be6c95a](https://github.com/angular/angular/commit/be6c95a))

### DEPRECATIONS

* `OpaqueToken` is now deprecated, use `InjectionToken<T>` instead.
* `Injector.get(token: any, notFoundValue?: any): any` is now deprecated
  use the same method which is now overloaded as
  `Injector.get<T>(token: Type<T>|InjectionToken<T>, notFoundValue?: T): T;`

### BREAKING CHANGES

* core: - Because `injector.get()` is now parameterize it is possible that code
  which used to work no longer type checks. Example would be if one
  injects `Foo` but configures it as `{provide: Foo, useClass: MockFoo}`.
  The injection instance will be that of `MockFoo` but the type will be
  `Foo` instead of `any` as in the past. This means that it was possible
  to call a method on `MockFoo` in the past which now will fail type
  check. See this example:

```
class Foo {}
class MockFoo extends Foo {
  setupMock();
}

var PROVIDERS = [
  {provide: Foo, useClass: MockFoo}
];

...

function myTest(injector: Injector) {
  var foo = injector.get(Foo);
  // This line used to work since `foo` used to be `any` before this
  // change, it will now be `Foo`, and `Foo` does not have `setUpMock()`.
  // The fix is to downcast: `injector.get(Foo) as MockFoo`.
  foo.setUpMock();
}
```

### Note ###

Due to regression in the 2.3.0 release that was fixed by [#13464](https://github.com/angular/angular/pull/13464),
components that have been compiled using 2.3.0 and published to npm will need to be recompiled and republished.

The >=2.3.1 compiler will issue is the following error if it encounters components compiled with 2.3.0:
`Unsupported metadata version 2 for module ${module}. This module should be compiled with a newer version of ngc`.

We are adding more tests to our test suite to catch these kinds of problems before we cut a release.

### Code Refactoring

* **core:** remove `…Metadata` for all decorators and use the decorator directly. ([63e15ff](https://github.com/angular/angular/commit/63e15ff))


### PEER-DEPENDENCY UPDATES ###

* **core**: zone.js@0.6.21
* **core**: rxjs@5.0.0-beta.12


### BREAKING CHANGES

* core: - all `…Metadata` classes have been removed. Use the corresponding decorator
  as constructor or for `instanceof` checks instead.

  * Before: `new ComponentMetadata(…)`
  * After: `new Component(…)`
- Note: `new Component(…)` worked before as well.

### PEER-DEPENDENCY UPDATES ###

* **core**: zone.js@0.6.17
* **core**: rxjs@5.0.0-beta.11
* **core**: reflect-metadata dependency is now optional when in AOT mode
* **compiler-cli**: typescript@2.0.2


### BREAKING CHANGES

* npm packages: code in ESM (ES6 Modules) format is now published at the default location in the npm package with `package.json`'s `main` entry pointing to an UMD bundle (primarily for node, and webpack 1 users).

  If you are using SystemJS to load Angular, you should adjust your SystemJS configuration to point to the UMD bundles (present in the npm package).

  Please see this [example SystemJS config](https://github.com/angular/quickstart/blob/3b7452cc444c49c139ea39523ced0468c2362c16/systemjs.config.js#L17-L34).

* testing config: due to zone.js peer-dependency upgrade, the order in which various zone specs are loaded has changed.

  Please see this [example Karma config](https://github.com/angular/quickstart/blob/3b7452cc444c49c139ea39523ced0468c2362c16/karma.conf.js#L31-L38).

* core: `Type` is now `Type<T>` which means that in most cases you have to
use `Type<any>` in place of `Type`.

  We don't expect that any user applications use the `Type` type directly.

* core: Previously inconsistently named APIs SanitizationService and DomSanitizationService were renamed to Sanitizer and DomSanitizer

* core: previously deprecated @Component.directives and @Component.pipes support was removed.

  All the components and pipes now must be declared via an NgModule. NgModule is the basic compilation block passed into the Angular compiler via Compiler#compileModuleSync or #compileModuleAsync.

  Because of this change, the Compiler#compileComponentAsync and #compileComponentSync were removed as well - any code doing compilation should compile module instead using the APIs mentioned above.

  Lastly, since modules are the basic compilation unit, the ngUpgrade module was modified to always require an NgModule to be passed into the UpgradeAdapter's constructor - previously this was optional.

* core: deprecated ComponentResolver was removed. Please use ComponentFactoryResolver instead.

* core: animations defined using an at-symbol prefix that are not property bound are now invalid.

  ```html
  <!-- this is now invalid -->
  <div @flip="flipState"></div>

  <!-- change that to -->
  <div [@flip]="flipState"></div>
  ```

* core: Animations that are not bound using the at-symbol
prefix using `animate-` must now be preixed using `bind-animate-`.

```html
<!-- this is now invalid -->
<div animate-flip="flipState"></div>

<!-- is valid now -->
<div bind-animate-flip="flipState"></div>
```

* core: These forms of providers are no longer accepted:
  ```
  bind(MyClass).toFactory(...)
  new Provider(MyClass, toFactory: ...)
  ```

  We now only accept:
  ```
  {provide: MyClass, useFactory: ...}
  ```

* core: previously deprecated NgZoneError has been removed

* core: Exceptions are no longer part of the public API. We don't expect that anyone should be referring to the Exception types.

  ```
  ExceptionHandler.call(exception: any, stackTrace?: any, reason?: string): void;
  ```
  change to:
  ```
  ErrorHandler.handleError(error: any): void;
  ```

* core: deprecated DynamicComponentLoader was removed; see deprecation notice for migration instructions.

* core: deprecated SystemJsComponentResolver and SystemJsCmpFactoryResolver have been removed.

* core: previously deprecated coreBootstrap and coreLoadAndBootstrap have been removed.

* core: all previously deprecated ApplicationRef apis have been removed.

* core: deprecated PlatformRef#registerDisposeListener, #disposed, #dispose() - follow deprecation instructions to upgrade

* core: deprecated disposePlatform was removed; see deprecation notice for migration instructions.

* core: deprecated DirectiveMetadataType#properties and DirectiveMetadataType#events were removed; see deprecation notice for migration instructions.

* core: deprecated lockRunMode was removed; see deprecation notice for migration instructions.

* core: deprecated DebugNode#inject was removed, see deprecation notice for migration instructions.

* core: deprecated Query and ViewQuery  were removed; see deprecation notice for migration instructions.

* core/testing: deprecated TestComponentBuilder was removed, please use TestBed instead

* compiler: Previously deprecated`#` and `var` are not supported any more in expressions within templates, use `let`:
  - `var-<name>` cannot be used any more on templates, use `let-<name>`
  - `var-<name>` cannot be used any more to create a reference, use `ref-<name>`

* http: any code which relies on the fact that a newly created Headers object is referencing an existing Headers map is now broken, but that should normally not be the case since this behavior is not documented and not in accordance with the spec.

* http: previously deprecated HTTP_PROVIDERS and JSONP_PROVIDERS were removed; see deprecation notice for migration instructions.

* platform-browser-dynamic: `CACHED_TEMPLATE_PROVIDER` is now renamed to `RESOURCE_CACHE_PROVIDER`

  Before:

  ```js
  import {CACHED_TEMPLATE_PROVIDER} from '@angular/platform-browser-dynamic';
  ```

  After:

  ```js
  import {RESOURCE_CACHE_PROVIDER} from '@angular/platform-browser-dynamic';
  ```

* common: previously deprecated NgSwitchWhen directive was removed, use NgSwitchCase instead

* common: previously deprecated ReplacePipe was removed

* upgrade: deprecated UpgradeAdapter#addProvider was removed, see deprecation notice for migration instructions.

* forms: deprecated `provideForms()` and `disableDeprecatedForms()` functions have been removed. Please import the `FormsModule` or the `ReactiveFormsModule` from @angular/forms instead.

* forms: deprecated forms APIs in @angular/common have been removed. Please update to the new forms API in @angular/forms. See angular.io for more information.

* webworkers: web worker platform is now exported via separate packages.

  Please use @angular/platform-webworker and @angular/platform-webworker-dynamic

### BREAKING CHANGES

* core:

  ## Bootstrap changes
  ```
  import {NgModule} from '@angular/core';

  @NgModule({
    declarations: […], // directives, components, and pipes owned by this NgModule
    imports: [BrowserModule],
    providers: […], // additional providers
    bootstrap: [MainComponent],
  })
  class MyAppModule {}

  // Ahead of Time compile
  import {platformBrowser} from ‘@angular/platform-browser’;

  platformBrowser().bootstrapModuleFactory(MyAppModuleNgFactory);

  // JIT compile long form
  import {platformBrowserDynamic} from ‘@angular/platform-browser-dynamic’;

  platformBrowserDynamic().bootstrapModule(MyAppModule);
  ```
* browser:
  - short form bootstrap does no longer allow
    to inject compiler internals (i.e. everything
    from `@angular/compiler`). Inject `Compiler` instead.
* core:
  - `ApplicationRef.waitForAsyncInitializers` is deprecated. Use
  `AppInitStatus.donePromise` / `AppInitStatus.done` instead.
* core:
  - `ApplicationRef.registerBootstrapListener` is deprecated. Provide a multi
  provider for the new token `APP_BOOTSTRAP_LISTENER` instead.
* core:
  - `ApplicationRef.dispose` is deprecated. Destroy the module that was
    created during bootstrap instead by calling `NgModuleRef.destroy`.
  - `ApplicationRef.registerDisposeListener` is deprecated.
    Use the `ngOnDestroy` lifecycle hook for providers or
    `NgModuleRef.onDestroy` instead.
  - `disposePlatform` is deprecated. Use `destroyPlatform` instead.
  - `PlatformRef.dipose()` is deprecated. Use `PlatformRef.destroy()`
    instead.
  - `PlatformRef.registerDisposeListener` is deprecated. Use
    `PlatformRef.onDestroy` instead.
  - `PlaformRef.diposed` is deprecated. Use `PlatformRef.destroyed`
    instead.
* testing:
  * `withProviders`, use `TestBed.withModule` instead
  * `addProviders`, use `TestBed.configureTestingModule` instead
  * `TestComponentBuilder`, use `TestBed.configureTestModule` / `TestBed.override...` / `TestBed.createComponent` instead.
* core:
  - ES5 users can no longer use the `View(…)` function to provide `ViewMetadata`.
  This mirrors the removal of the `@View` decorator a while ago.
* core:
  - `bootstrapModule` and `bootstrapModuleFactory` have been moved to be members of `PlaformRef`.
    E.g. `platformBrowserDynamic().bootstrapModule(MyModule)`.
* core:
  - By default, Angular will error during parsing
  on unknown properties,
  even if they are on elements with a `-` in their name
  (aka custom elements). If you application is using
  custom elements, fill the new parameter `@NgModule.schemas`
  with the value `[CUSTOM_ELEMENTS_SCHEMA]`.

  E.g. :
  ```
    @NgModule({
      declarations: [MyComponentThatUsesAWebComponent],
      imports: [BrowserModule],
      schemas: [CUSTOM_ELEMENTS_SCHEMA],
      bootstrap:  [MyComponentThatUsesAWebComponent],
    })
    export class MyAppModule{}
  ```
* core:
  - `coreLoadAndBootstrap` and `coreBootstrap` can't be used any more (without migration support).
    Use `bootstrapModule` / `bootstrapModuleFactory` instead.
  - All Components listed in routes have to be part of the `declarations` of an NgModule.
    Either directly on the bootstrap module / lazy loaded module, or in an NgModule imported by them.
* core:
  - `ApplicationRef.run` is deprecated. Use `NgZone.run` directly
  - `ApplicationRef.injector` is deprecated. Inject an `Injector` or
    use `NgModuleRef.injector` instead
  - `ApplicationRef.zone` is deprecated. Inject `NgZone` instead.
* testing: `TestInjector` is now renamed to `TestBed`

  Before:

  ```js
  import {TestInjector, getTestInjector} from '@angular/core/testing';
  ```

  After:

  ```js
  import {TestBed, getTestBed} from '@angular/core/testing';
  ```
* http: The behavior in this commit is the same as before PR 7260 : the objects sent with the request are converted to a string, therefore there is no need for the user to take care of the serialization.
* platform-browser: The following API was never intended to be public and is removed:

  ```js
  import {verifyNoBrowserErrors} from '@angular/platform-browser/testing_e2e';
  ```

  Consider using Protractor's console plugin: https://github.com/angular/protractor-console-plugin
* ICU:

  "{" is used a a delimiter for ICU messages then it could not be used in text nodes.
  "{" should be escaped as "{{ '{' }}"

  Before:

      <span>some { valid } text</span>

  After:

      <span>some { invalid } text<span> <!-- throw parse error -->
      <span>some {{ '{' }} valid } text</span>
* core: (deprecations)

  - Instead of `coreBootstrap`, create an `@NgModule` and use `bootstrapModule`.
  - Instead of `coreLoadAndBootstarp`, create an `@NgModule` and use `bootstrapModuleFactory`.
  - Instead of `bootstrapWorkerApp`, create an `@NgModule` that includes the `WorkerAppModule` and use `bootstrapModule` with the `workerAppPlatform()`.
  - Instead of `bootstrapWorkerUi`, create an @AppModule that includes the `WorkerUiModule` and use `bootstrapModule` with the `workerUiPlatform()` instead.
  - Instead of `serverBootstrap`, create an @AppModule and use `bootstrapModule` with the `serverDynamicPlatform()` instead.
  - Instead of `PLATFORM_PIPES` and `PLATFORM_DIRECTIVES`, provide platform directives/pipes via an `@NgModule`.
  - Instead of `ComponentResolver`:
    - use `ComponentFactoryResolver` together with `@NgModule.entryComponents` or `ANALYZE_FOR_ENTRY_COMPONENTS` provider for dynamic component creation.
    - use `NgModuleFactoryLoader` for lazy loading.
  - Instead of `SystemJsComponentResolver`, create an `@NgModule` and use `SystemJsNgModuleLoader`.
  - Instead of `SystemJsCmpFactoryResolver`, create an `@NgModule` and use `SystemJsNgModuleFactoryLoader`
* core:
  - `lockRunMode` is deprecated and no more needed.
* animations:
  - animation trigger expressions within the template that are assigned as
  an element attribute (e.g. `@prop`) are deprecated. Please use the
  Angular2 property binding syntax (e.g. `[@prop]`) when assigning
  properties.

  ```ts
  // this is now deprecated
  <div @trigger="expression"></div>

  // do this instead
  <div [@trigger]="expression"></div>
  ```

* forms:

  We have removed the deprecated form directives from the built-in platform directive list, so apps are not required to package forms with their app. This also makes forms friendly to offline compilation.

  Instead, we have exposed three modules:

  OLD API:
  - `DeprecatedFormsModule`

  NEW API:
  - `FormsModule`
  - `ReactiveFormsModule`

  If you provide one of these modules, the default forms directives and providers from that module will be available to you app-wide.  Note: You can provide both the `FormsModule` and the `ReactiveFormsModule` together if you like, but they are fully-functional separately.

  **Before:**
  ```ts
  import {disableDeprecatedForms, provideForms} from @angular/forms;

  bootstrap(App, [
    disableDeprecatedForms(),
    provideForms()
  ]);
  ```

  **After:**

  ```ts
  import {DeprecatedFormsModule} from @angular/common;

  @NgModule({
    declarations: [MyComponent],
    imports: [BrowserModule, DeprecatedFormsModule],
    bootstrap:  [MyComponent],
  })
  export class MyAppModule{}
  ```
* testing:
  - Application providers can no longer inject compiler internals (i.e. everything
  from `@angular/compiler`). Inject `Compiler` instead. This reflects the
  changes to `bootstrap` for module support (3f55aa609f60f130f1d69188ed057214b1267cb3).
  - Compiler providers can no longer be added via `addProviders` / `withProviders`.
    Use the new method `configureCompiler` instead.
  - Platform directives / pipes need to be provided via
    `configureModule` and can no longer be provided via the
    `PLATFORM_PIPES` / `PLATFORM_DIRECTIVES` tokens.
  - `setBaseTestProviders()` was renamed into `initTestEnvironment` and
    now takes a `PlatformRef` and a factory for a
    `Compiler`.
  - E.g. for the browser platform:

    BEFORE:
    ```
    import {setBaseTestProviders} from ‘@angular/core/testing’;
    import {TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
        TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS} from ‘@angular/platform-browser-dynamic/testing’;

    setBaseTestProviders(TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
        TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS);
    ```

    AFTER:
    ```
    import {TestBed} from ‘@angular/core/testing’;
    import {BrowserDynamicTestingModule, platformBrowserDynamicTesting} from ‘@angular/platform-browser-dynamic/testing’;

    TestBed.initTestEnvironment(
        BrowserDynamicTestingModule,
        platformBrowserDynamicTesting()
        );

    ```
  - E.g. for the server platform:

    BEFORE:
    ```
    import {setBaseTestProviders} from ‘@angular/core/testing’;
    import {TEST_SERVER_PLATFORM_PROVIDERS,
        TEST_SERVER_APPLICATION_PROVIDERS} from ‘@angular/platform-server/testing/server’;

    setBaseTestProviders(TEST_SERVER_PLATFORM_PROVIDERS,
        TEST_SERVER_APPLICATION_PROVIDERS);
    ```

    AFTER:
    ```
    import {TestBed} from ‘@angular/core/testing’;
    import {ServerTestingModule, serverTestingPlatform} from ‘@angular/platform-browser-dynamic/testing’;

    TestBed.initTestEnvironment(
        ServerTestingModule,
        serverTestingPlatform()
        );
    ```

  Related to #9726
* ngUpgrade: UpgradeAdapter.addProvider are now deprecated in favor of passing in an NgModule into the adapter's constructor

  Before:

  ```
  let upgradeAdapter = new UpgradeAdapter();
  upgradeAdapter.addProviders([myProvidersArray);
  ```

  After:

  ```
  @NgModule({
    providers: myProvidersArray
  })
  class MyModule {}

  let upgradeAdapter = new UpgradeAdapter(MyModule);
  ```

  * ngModel: `ngModel` is now always asynchronous when updating. This means that in tests, instead of calling `ComponentFixture.detectChanges`, you'll need to use `ComponentFixture.whenStable`, which is asynchronous.

  Before:

  ```js
      let fixture = TestBed.createComponent(InputComp);
      fixture.detectChanges();

      let inputBox = <HTMLInputElement> fixture.debugElement.query(By.css('input')).nativeElement;
      expect(inputBox.value).toEqual('Original Name');
  ```

  After:
  ```js
      let fixture = TedBed.createComponent(InputComp);
      fixture.whenStable().then(() => {
        let inputBox = <HTMLInputElement> fixture.debugElement.query(By.css('input')).nativeElement;
        expect(inputBox.value).toEqual('Original Name');
     });
  ```

### BREAKING CHANGES

* http: The changes to Http's URLSearchParams serialization now
  prevent encoding of these characters inside query parameters
  which were previously converted to percent-encoded values `@ : $ , ; + ; ? /`

  The default encoding behavior can be overridden by extending
  QueryEncoder, as documented in the URLSearchParams service.
* Previously multiple template bindings on one element
  (ex. `<div *ngIf='..' *ngFor='...'>`) were allowed but most of the time
  were leading to undesired result. It is possible that a small number
  of applications will see template parse errors that should be fixed by
  nesting elements or using `<template>` tags explicitly.
* DomEventsPlugin and KeyEventsPlugin previously exported from core are no longer public - these classes are implementation detail.

  Previously deprecated BROWSER_PROVIDERS was completely removed from platform-browser.
* core/testing compiler/testing: `TestComponentBuilder` is now imported from `@angular/core/testing`. Imports
  from `@angular/compiler/testing` are deprecated.

  Before:

  ```
  import {TestComponentBuilder, TestComponentRenderer, ComponentFixtureAutoDetect} from '@angular/compiler/testing';
  ```

  After:
  ```
  import {TestComponentBuilder, TestComponentRenderer, ComponentFixtureAutoDetect} from '@angular/core/testing';
  ```
* common/testing: MockLocationStrategy was intended to be internal only and is now removed
  from the `@angular/common/testing` public api.

  Use `SpyLocation` from `@angular/common/testing` for location testing.
* compiler: `TestComponentBuilder.createSync` now takes a component type
  and throws if not all templates are either inlined
  are compiled before via `createAsync`.
* core/testing: Remove the following APIs from `@angular/core/testing`, which have been deprecated or were
  never intended to be publicly exported:

  ```
  injectAsync
  clearPendingTimers
  Log
  MockAppliacationHref
  MockNgZone
  clearPendingTimers
  getTypeOf
  instantiateType
  ```

  Instead of `injectAsync`, use `async(inject())`.

  `clearPendingTimers` is no longer required.
* platform-browser/testing: The following are no longer publicly exported APIs. They were intended as internal
  utilities and you should use your own util:

  ```
  browserDetection,
  dispatchEvent,
  el,
  normalizeCSS,
  stringifyElement,
  expect (and custom matchers for Jasmine)
  ```
* testing:

  Before:

      expect(...).toThrowErrorWith(msg);

  After:

      expect(...).toThrowError(msg);

  Before:

      expect(...).toMatchPattern(pattern);

  After:

      expect(...).toMatch(pattern);
* core/testing: `ComponentFixture` will be moving out of `@angular/compiler/testing` to `@angular/core/testing` in
  this release. For now, it is deprecated from `@angular/compiler/testing`.


* The async function now determines whether it should return a promise
  or instead call a done function parameter. Importing Jasmine functions
  from `@angular/core/testing` is no longer necessary and is now deprecated.

  Additionally, beforeEachProviders is also deprecated, as it is specific
  to the testing framework. Instead, use the new addProviders method directly.

  Before:
  ```js
  import {beforeEachProviders, it, describe, inject} from '@angular/core/testing';

  describe('my code', () => {
    beforeEachProviders(() => [MyService]);

    it('does stuff', inject([MyService], (service) => {
      // actual test
    });
  });
  ```

  After:
  ```js
  import {addProviders, inject} from '@angular/core/testing';

  describe('my code', () => {
    beforeEach(() => {
      addProviders([MyService]);
    });

    it('does stuff', inject([MyService], (service) => {
      // actual test
    }));
  });
  ```

### BREAKING CHANGES
* Location#platformStrategy property was previously accidentally exported as public
If any application requires access to the current location strategy, it should be accessed via DI instead
by injecting the LocationStrategy token.
The likelihood of anyone actually depending on this property is very low.

* DirectiveNormalizer takes new constructor arguments, `config:CompilerConfig`.

* `Parser` constructor required new parameter `config: CompilerConfig` as second argument.

* Bundles are now in the bundles/ subdirectory within each package

* HTML, style values, and URLs are now automatically sanitized. Values that do not match are escaped
  or ignored. When binding a URL or style property that would get ignored, bind to a value
  explicitly marked as safe instead by injection the DOM sanitization service:

  ```
  class MyComponent {
    constructor(sanitizer: DomSanitizationService) {
      // ONLY DO THIS FOR VALUES YOU KNOW TO BE SAFE! NEVER ALLOW USER DATA IN THIS!
      this.safeStyleValue = sanitizer.bypassSecurityTrustStyle('rotate(90deg)');
      // then bind to `safeStyleValue` in your template.
    }
  }
  ```

* `PLATFORM_PIPES` and `PLATFORM_DIRECTIVES` now are fields on `CompilerConfig`.
  Instead of providing a binding to these tokens, provide a binding for `CompilerConfig` instead.

* `CompilerConfig` used to take positional arguments and now takes named arguments.

### Deprecation

* `Parse5DomAdapter` will no longer be exported from `@angular/platform-server` as a public API as of RC.3.
  A new function called `serverBootstrap()` will be provided, which will automatically set the correct
  `document` during platform initialization.

### Reverts

* Revert fix(compiler): support string tokens with `.` inside. ([cc86fee](https://github.com/angular/angular/commit/cc86fee))

<a name="2.0.0-rc.1"></a>
# 2.0.0-rc.1 (2016-05-03)

### Known Issues

*** SECURITY WARNING ***
Contextual escaping is not yet implemented in Angular. This will be fixed in the upcoming RC.
In the meantime make sure to correctly escape all values that go into the DOM.
*** SECURITY WARNING ***

- source maps for umd bundles are missing
- `Ruler` service is not being reexported via `@angular/platform-browser`

<a name="2.0.0-rc.0"></a>
# 2.0.0-rc.0 (2016-05-02)

This is the first release candidate that contains repackaging of Angular into individual packages one per each feature area.

All of the packages are now distributed under the @angular npm scope. This changes how Angular is installed via npm and how you import the code.

To install Angular for a browser application please use:

```
npm install --save @angular/core @angular/compiler @angular/common @angular/platform-browser @angular/platform-browser-dynamic rxjs@5.0.0-beta.6 zone.js@0.6.12
```

To import various symbols please adjust the paths in the following way:

- `angular2/core` -> `@angular/core`
- `angular2/compiler` -> `@angular/compiler`
- `angular2/common` -> `@angular/common`
- `angular2/platform/browser` -> `@angular/platform-browser` (applications with precompiled templates) + `@angular/platform-browser-dynamic` (applications that compile templates on the fly)
- `angular2/platform/server` -> `@angular/platform-server`
- `angular2/testing` -> `@angular/core/testing` (it/describe/..) + `@angular/compiler/testing` (TestComponentBuilder) + `@angular/platform-browser/testing`
- `angular2/upgrade` -> `@angular/upgrade`
- `angular2/http` -> `@angular/http`
- `angular2/router` -> `@angular/router-deprecated` (snapshot of the component router from beta.17 for backwards compatibility)
- new package: `@angular/router` - component router with several [breaking changes](https://docs.google.com/document/d/1WLSNV3V1AKdwLwRiLuN7JqbPBKQ_S5quRlcT5LPIldw/edit#heading=h.blfh5ya9sf5r)

### OTHER BREAKING CHANGES


* - ViewRef.changeDetectorRef was removed as using ChangeDetectorRefs
  for EmbeddedViewRefs does not make sense. Use ComponentRef.changeDetectorRef
  or inject ChangeDetectorRef instead.

* - Before, a `EmbeddedViewRef` used to have methods for
  setting variables. Now, a user has to pass in a context
  object that represents all variables when an `EmbeddedViewRef`
  should be created.
- `ViewContainerRef.createEmbeddedViewRef` now takes
   a context object as 2nd argument.
- `EmbeddedViewRef.setLocal` and `getLocal` have been removed.
  Use `EmbeddedViewRef.context` to access the context.
- `DebugNode.locals` has been removed. Use the new methods `DebugElement.references`
  to get the references that are present on this element,
  or `DebugElement.context` to get the context of the `EmbeddedViewRef` or the component to which the element belongs.
* - Depending on if you are using precompiled templates or you are compiling templates on the fly, the setup for the base test providers has changed:

Before:
```js
// Somewhere in test setup
import {setBaseTestProviders} from 'angular2/testing';
import {
  TEST_BROWSER_PLATFORM_PROVIDERS,
  TEST_BROWSER_APPLICATION_PROVIDERS
} from 'angular2/platform/testing/browser';
setBaseTestProviders(TEST_BROWSER_PLATFORM_PROVIDERS,
                     TEST_BROWSER_APPLICATION_PROVIDERS);
```
After (applications that compile templates on the fly):
```js
// Somewhere in the test setup
import {setBaseTestProviders} from '@angular/core/testing';
import {
  TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
  TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS
} from '@angular/platform-browser-dynamic/testing';
setBaseTestProviders(TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
                     TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS);
```

After (applications with precompiled templates):
```js
// Somewhere in the test setup
import {setBaseTestProviders} from '@angular/core/testing';
import {
  TEST_BROWSER_STATIC_PLATFORM_PROVIDERS,
  TEST_BROWSER_STATIC_APPLICATION_PROVIDERS
} from '@angular/platform-browser/testing';
setBaseTestProviders(TEST_BROWSER_STATIC_PLATFORM_PROVIDERS,
                     TEST_BROWSER_STATIC_APPLICATION_PROVIDERS);
```

### BREAKING CHANGES

The reference `#...` now always means `ref-`.

**Before:**
- Outside of `ngFor`, a `#...` meant a reference.
- Inside of `ngFor`, it meant a local variable.

This pattern was confusing.

**After:**

- `<template #abc>` now defines a reference to a TemplateRef, instead of an input variable used inside of the template.
- Inside of structural directives that declare local variables, such as `*ngFor`, usage of `#...` is deprecated. Use `let` instead.
  - `<div *ngFor="#item of items">` now becomes `<div *ngFor="let item of items">`
- `var-...` is deprecated.
  - use `#` or a `ref-` outside of `*ngFor`
  - for `ngFor`, use the syntax:  `<template ngFor let-... [ngForOf]="...">`

### BREAKING CHANGES

* - pipes now take a variable number of arguments, and not an array that contains all arguments.

* inject can no longer wrap fakeAsync while fakeAsync can wrap inject. So the order in existing tests with inject and fakeAsync has to be switched as follows:
Before:
```
inject([...], fakeAsync((...) => {...}))
```
After:
```
fakeAsync(inject([...], (...) => {...}))
```
You will also need to add the dependency
`'node_modules/zone.js/dist/fake-async-test.js'`
as a served file in your Karma or other test configuration.

* - Injector was renamed into `ReflectiveInjector`,
  as `Injector` is only an abstract class with one method on it
- `Injector.getOptional()` was changed into `Injector.get(token, notFoundValue)`
  to make implementing injectors simpler
- `ViewContainerRef.createComponent` now takes an `Injector`
  instead of `ResolvedProviders`. If a reflective injector
  should be used, create one before calling this method.
  (e.g. via `ReflectiveInjector.resolveAndCreate(…)`.

* - `DynamicComponentLoader.loadIntoLocation` has been removed. Use `@ViewChild(‘myVar’, {read: ViewContainerRef})` to get hold of a `ViewContainerRef` at an element with variable `myVar`. Then call `DynamicComponentLoader.loadNextToLocation`.
- `DynamicComponentLoader.loadNextToLocation` now takes a `ViewContainerRef` instead of an `ElementRef`.
- `AppViewManager` is renamed into `ViewUtils` and is a mere private utility service.

* - `Compiler` is renamed to `ComponentResolver`,
  `Compiler.compileInHost` has been renamed to `ComponentResolver.resolveComponent`.
- `ComponentRef.dispose` is renamed to `ComponentRef.destroy`
- `ViewContainerRef.createHostView` is renamed to `ViewContainerRef.createComponent`
- `ComponentFixture_` has been removed, the class `ComponentFixture`
  can now be created directly as it is no more using private APIs.

* `Location` and other related providers have been moved out of `router` and into `platform/common`. `BrowserPlatformLocation` is not meant to be used directly however advanced configurations may use it via the following import change.
Before:
```
import {
  PlatformLocation,
  Location,
  LocationStrategy,
  HashLocationStrategy,
  PathLocationStrategy,
  APP_BASE_HREF}
from 'angular2/router';
import {BrowserPlatformLocation} from 'angular2/src/router/location/browser_platform_location';
```
After:
```
import {
  PlatformLocation,
  Location,
  LocationStrategy,
  HashLocationStrategy,
  PathLocationStrategy,
  APP_BASE_HREF}
from 'angular2/platform/common';
import {BrowserPlatformLocation} from 'angular2/src/platform/browser/location/browser_platform_location';
```

* `injectAsync` is now deprecated. Instead, use the `async` function
to wrap any asynchronous tests.

You will also need to add the dependency
`'node_modules/zone.js/dist/async-test.js'`
as a served file in your Karma or other test configuration.

Before:
```
it('should wait for returned promises', injectAsync([FancyService], (service) => {
  return service.getAsyncValue().then((value) => { expect(value).toEqual('async value'); });
}));
it('should wait for returned promises', injectAsync([], () => {
  return somePromise.then(() => { expect(true).toEqual(true); });
}));
```
After:
```
it('should wait for returned promises', async(inject([FancyService], (service) => {
  service.getAsyncValue().then((value) => { expect(value).toEqual('async value'); });
})));
// Note that if there is no injection, we no longer need `inject` OR `injectAsync`.
it('should wait for returned promises', async(() => {
  somePromise.then(() => { expect(true).toEqual(true); });
}));
```

* - Renderer:
  * renderComponent method is removed form `Renderer`, only present on `RootRenderer`
  * Renderer.setDebugInfo is removed. Renderer.createElement / createText / createTemplateAnchor
    now take the DebugInfo directly.
- Query semantics:
  * Queries don't work with dynamically loaded components.
  * e.g. for router-outlet: loaded components can't be queries via @ViewQuery,
    but router-outlet emits an event `activate` now that emits the activated component
- Exception classes and the context inside changed (renamed fields)
- DebugElement.attributes is an Object and not a Map in JS any more
- ChangeDetectorGenConfig was renamed into CompilerConfig
- AppViewManager.createEmbeddedViewInContainer / AppViewManager.createHostViewInContainer
  are removed, use the methods in ViewContainerRef instead
- Change detection order changed:
  * 1. dirty check component inputs
  * 2. dirty check content children
  * 3. update render nodes

### BREAKING CHANGES

* For static content projection, elements with *-directives are now matched against the element itself vs the template before.

`<p *ngIf="condition" foo></p>`

Before:
```html
    // Use the implicit template for projection
    <ng-content select="template"></ng-content>
```

After:
```html
    // Use the actual element for projection
    <ng-content select="p[foo]"></ng-content>
```

### BREAKING CHANGES

* `OnPushObserve` was an experimental
feature for Dart and had
conceptual performance problems,
as setting up observables is slow.
Use `OnPush` instead.

* 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.

* The `$router` injectable service has been renamed to `$rootRouter`

* The recently added binding of the current router to the current component
has been renamed from `router` to `$router`.
So now the recommended set up for your bindings in your routed component
is:
```js
{
  ...
  bindings: {
    $router: '<'
  }
}
```

### Features

* **angular1_router:** allow component to bind to router ([0f22dce](https://github.com/angular/angular/commit/0f22dce))
* **typings:** install es6-shim typings to a location users can reference. ([f1f5b45](https://github.com/angular/angular/commit/f1f5b45))

### BREAKING CHANGES

Transitive typings are no longer included in the distribution.

If you use `--target=es5`, you will need to add a line somewhere in your
application (for example, at the top of the `.ts` file where you call `bootstrap`):
```
///<reference path="node_modules/angular2/typings/browser.d.ts"/>
```
(Note that if your file is not in the same directory as `node_modules`, you'll
need to add one or more `../` to the start of that path.)

If you have unit tests, you need to install typings in your project using
http://github.com/typings/typings
And install typings such as `jasmine`, `angular-protractor`, or `selenium-webdriver`
to satisfy the type-checker.

If you rely on es6 APIs other than Promises and Collections, you will need to
install the es6-shim typing instead of using the `<reference>` tag above.
Angular previously exposed typings for the entire ES6 API.

* **WebWorker:** Add Router Support for WebWorker Apps ([8bea667](https://github.com/angular/angular/commit/8bea667)), closes [#3563](https://github.com/angular/angular/issues/3563)

### Performance Improvements

* **dart/transform:** Only process deferred libs when necessary ([f56df65](https://github.com/angular/angular/commit/f56df65)), closes [#6745](https://github.com/angular/angular/issues/6745)

### BREAKING CHANGES

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;
```

### Bug Fixes

* **bundles:** don't include RxJS in System.register bundles ([77b7cae](https://github.com/angular/angular/commit/77b7cae))
* **bundles:** remove ngUpgrade from the angular2.js bundle ([283962f](https://github.com/angular/angular/commit/283962f)), closes [#5739](https://github.com/angular/angular/issues/5739) [#5854](https://github.com/angular/angular/issues/5854)

* **bundles:** rename the testing.js bundle to testing.dev.js ([d55655f](https://github.com/angular/angular/commit/d55655f)), closes [#5899](https://github.com/angular/angular/issues/5899) [#5776](https://github.com/angular/angular/issues/5776)
* **bundles:** rename UMD bundles ([61b9468](https://github.com/angular/angular/commit/61b9468)), closes [#5898](https://github.com/angular/angular/issues/5898)


### BREAKING CHANGES

* System.register testing bundle was renamed:
`testing.js` -> `testing.dev.js`

* UMD bundles were renamed:
  * `angular2.umd.js` -> `angular2-all.umd.js`
  * `angular2-testing.umd.js` -> `angular2-all-testing.umd.js`

* RxJS used to be bundled with Angular code and this is not the case
any more. RxJS needs to be loaded explicitly.

* Previously `angular2.js`, `angular2.min.js` and `angular2.dev.js` bundles
would have zone.js and reflect-metadata pre-appended. New bundles don't
contain zone.js nor reflect-metadata - those external dependencies can
be easily loaded into a browser using `angular2-polyfills.js`

* `ngUpgrade` related symbols are no longer part of the `angular2.js`
bundle. `ngUpgrade` has a dedicated `upgrade.js` bundle now.

Note: This only applies to JavaScript, Dart is not changed.

* The following symbols are not exported from angular2/angular2 any more:
`UrlResolver`, `AppRootUrl`, `getUrlScheme`, `DEFAULT_PACKAGE_URL_PROVIDER`.

### BREAKING CHANGES

* The existing sfx bundle (angular2.sfx.dev.js) is replaced by UMD bundles:
angular2.umd.js and angular2.umd.dev.js. The new UMD bundles dont have
polyfills (zone.js, reflect-metadata) pre-appended. Those polyfills
can be easily loaded by including the angular-polyfills.js bundle.

* The `external-dependencies.js` bundle was removed.
Use `angular-polyfills.js` instead.

* Number and content of UMD bundles have changed:
- we only publish one bundle that contains: core, common, platform/browser, http, router, instrumentation and upgrade
- exported names have changed and now:
  - core is exported as `ng.core`
  - common is exported as `ng.common`
  - platform/browser is exported as `ng.platform.browser`
  - http is exported as `ng.http`
  - router is exported as `ng.router`
  - instrumentation is exported as `ng.instrumentation`
  - upgrade is exported as `ng.upgrade`

* Form directives are exportedAs 'ngForm' (was 'form')

    Before:
      ```html
        <form #f="form">
      ```

    After:
      ```html
        <form #f="ngForm">
      ```
* rxjs, reflect-metadata, zone.js and es6-shims now must be specified as
  explicit dependencies of each angular app that uses npm for package management.

  To migrate, please add the following into the "dependencies" section of your package.json:

  ```
  "dependencies": {
      ...

      "es6-promise": "^3.0.2",
      "es6-shim": "^0.33.3",
      "reflect-metadata": "0.1.2",
      "rxjs": "5.0.0-alpha.11",
      "zone.js": "0.5.8"

      ...
  }
  ```

  or [check angular2's package.json](https://github.com/angular/angular/blob/master/package.json) for the latest `dependencies`

* **testing:** use zones to avoid the need for injectAsync ([0c9596a](https://github.com/angular/angular/commit/0c9596a))


### BREAKING CHANGES

* Previously http would only error on network errors to match the fetch
specification. Now status codes less than 200 and greater than 299 will
cause Http's Observable to error.

* A few private helpers (e.g., platformCommon or applicationCommon) were removed or replaced with other helpers. Look at PLATFORM_COMMON_PROVIDERS, APPLICATION_COMMON_PROVIDERS, BROWSER_PROVIDERS, BROWSER_APP_PROVIDERS to see if they export the providers you need.

* Previously, components that would implement lifecycle interfaces would include methods
like "onChanges" or "afterViewInit." Given that components were at risk of using such
names without realizing that Angular would call the methods at different points of
the component lifecycle. This change adds an "ng" prefix to all lifecycle hook methods,
far reducing the risk of an accidental name collision.

  To fix, just rename these methods:
  * onInit
  * onDestroy
  * doCheck
  * onChanges
  * afterContentInit
  * afterContentChecked
  * afterViewInit
  * afterViewChecked
  * _Router Hooks_
  * onActivate
  * onReuse
  * onDeactivate
  * canReuse
  * canDeactivate

  To:
  * ngOnInit,
  * ngOnDestroy,
  * ngDoCheck,
  * ngOnChanges,
  * ngAfterContentInit,
  * ngAfterContentChecked,
  * ngAfterViewInit,
  * ngAfterViewChecked
  * _Router Hooks_
  * routerOnActivate
  * routerOnReuse
  * routerOnDeactivate
  * routerCanReuse
  * routerCanDeactivate

  The names of lifecycle interfaces and enums have not changed, though interfaces
  have been updated to reflect the new method names.

### BREAKING CHANGES

* AMBIENT_DIRECTIVES -> PLATFORM_DIRECTIVES
* AMBIENT_PIPES -> PLATFORM_PIPES

* Previously, the controlsErrors getter of ControlGroup and ControlArray returned the errors of their direct children. This was confusing because the result did not include the errors of nested children (ControlGroup -> ControlGroup -> Control). Making controlsErrors to include such errors would require inventing some custom serialization format, which applications would have to understand.
Since controlsErrors was just a convenience method, and it was causing confusing, we are removing it. If you want to get the errors of the whole form serialized into a single object, you can manually traverse the form and accumulate the errors. This way you have more control over how the errors are serialized.

* **validators:** Allow errors at both the group/array level or their children ([28d88c5](https://github.com/angular/angular/commit/28d88c5))


### BREAKING CHANGES

#### ControlGroup.errors and ControlArray.errors have changed

* Before: ControlGroup.errors and ControlArray.errors returned a reduced value of their children controls' errors.
* After: ControlGroup.errors and ControlArray.errors return the errors of the group and array, and ControlGroup.controlsErrors and ControlArray.controlsErrors return the reduce value of their children controls' errors.

#### Errors format has changed from validators

Now errors from a control or an array's children are prefixed with 'controls' while errors from the object itself are left at the root level.

**Example:**
Given a Control group as follows:
```
var group = new ControlGroup({
  login: new Control("", required),
  password: new Control("", required),
  passwordConfirm: new Control("", required)
});
```

*Before:*
```
group.errors
{
  login: {required: true},
  password: {required: true},
  passwordConfirm: {required: true},
}
```

*After:*
```
group.errors
{
  controls: {
    login: {required: true},
    password: {required: true},
    passwordConfirm: {required: true},
  }
}
```

#### Pipes are now associated right to left

* Before: `1 + 1 | pipe:a | pipe:b` was parsed as `(1 + 1) | pipe:(a | pipe:b)`
* After: `1 + 1 | pipe:a | pipe:b` is parsed as `((1 + 1) | pipe:a) | pipe:b`

#### NgZone Moved to Stream/Observable-based callback API

* deprecates these methods in NgZone: overrideOnTurnStart, overrideOnTurnDone, overrideOnEventDone, overrideOnErrorHandler
* introduces new API in NgZone that may shadow other API used by existing applications.

#### Directives no longer match to variable names

You can no longer use a #foo or a var-foo to apply directive [foo], although it didn't work properly anyway.
This commit is fixing breakage caused by the switch to pre-compiler (exact SHA unknown).

#### Actions no longer support if statements

  - `bind` -> `provide`
  - `@Component(bindings: ...)` -> `@Component(providers: ...)`
  - `@Component(viewBindings: ...)` -> `@Component(viewProviders: ...)`
  - `HTTP_BINDINGS` -> `HTTP_PROVIDERS`

### BREAKING CHANGES

#### Query

[make QueryList notify on changes via an observable](https://github.com/angular/angular/commit/3aa2047)

* Before: query.onChange(() => ...);
* After: query.changes.subscribe((iterable) => {});

#### Router

[introduce new navigate method](https://github.com/angular/angular/commit/d9036c6)

Previously, `router.navigate` took a string representing the URL.
Now, it accepts an array that mirrors the link DSL.
The old `navigate` method has been renamed to `router.navigateByUrl`.
Either change your navigation calls to use the DSL (preferred) or
call `router.navigateByUrl` instead.

* Before:
router.navigate

* After:
router.navigateUrl


#### Pipes

[add support for pure pipes](https://github.com/angular/angular/commit/a8bdb69)
By default, pipes are pure. This means that an instance of a pipe will be reused and the pipe will be called only when its arguments change.

Before:

@Pipe({name: 'date'}) class DatePipe {} defines an impure pipe.

After:

@Pipe({name: 'date'}) class DatePipe {} defines a pure pipe.
@Pipe({name: 'date', pure: false}) class DatePipe {} defines an impure pipe.

* Before:
@Pipe({name: 'date'}) class DatePipe {} defines an impure pipe.
* After:
@Pipe({name: 'date'}) class DatePipe {} defines a pure pipe.
@Pipe({name: 'date', pure: false}) class DatePipe {} defines an impure pipe.

#### ViewQuery

[Implement query update mechanism based on views.](https://github.com/angular/angular/commit/5ebeaf7c9bdab8de6d11c7b4c4d0954553196903)

* ViewQuery no longer supports the descendants flag. It queries the whole
component view by default.

Instead of working with finer grained element injectors, queries now
iterate through the views as static units of modification of the
application structure. Views already contain element injectors in the
correct depth-first preorder.

This allows us to remove children linked lists on element injectors and a
lot of book keeping that is already present at the view level.

Queries are recalculated using the afterContentChecked and
afterViewChecked hooks, only during init and after a view container has
changed.

* Before:
@ViewQuery(SomeDirective, {descendants: true})) someDirective
* After:
@ViewQuery(SomeDirective) someDirective

#### DI

[add support for multi bindings](https://github.com/angular/angular/commit/7736964a37d17cf0f1e5381c9a95a33ee863f02f)
Previously a content binding of a component was visible to the directives in its view with the host constraint.
This is not the case any more. To access that binding, remove the constraint.

#### Core
[remove the (^ syntax and make all DOM events bubbling)](https://github.com/angular/angular/commit/60ce8846710338228bc7db3d3c808c166e15e931)

* Before
```html
<div (^click)="onEventHandler()">
  <button></button>
</div>
```
* After
```html
<div (click)="onEventHandler()">
  <button></button>
</div>
```

#### Properties/Events (Inputs/Outputs)

[Rename Property into Input and Event into Output](https://github.com/angular/angular/commit/adbfd29fd761135d51985564edcb4db7f8b6a26a)

* Before:
@Directive({properties: ['one'], events: ['two']})
* After:
@Directive({inputs: ['one'], outputs: ['two']})

* Before:
@Component({properties: ['one'], events: ['two']})
* After:
@Componet({inputs: ['one'], outputs: ['two']})

* Before:
class A {@Property() one; @Event() two;}
* After:
class A {@Input() one; @Output() two;}

#### Compiler

With a [new compiler](https://github.com/angular/angular/commit/76247b70973e3266e504e05381fbd7d85d4de5c6) `NgNonBindable`
 is not a directive but rather a special attribute (`ng-non-bindable`) recognized by the compiler. This means that you
can't import / use the `NgNonBindable` as a directive. You should remove all the imports for the the `NgNonBindable`
directive and all the references to it in the `directives` section of the `@View` decorator.

### BREAKING CHANGES

* rename all constants to UPPER_CASE names

  - `appComponentTypeToken` => `APP_COMPONENT`
  - `coreDirectives` => `CORE_DIRECTIVES`
  - `formDirectives` => `FORM_DIRECTIVES`
  - `formInjectables` => `FORM_BINDINGS`
  - `httpInjectables` => `HTTP_BINDINGS`
  - `jsonpInjectables` => `JSONP_BINDINGS`
  - `PROTO_CHANGE_DETECTOR_KEY` => `PROTO_CHANGE_DETECTOR`
  - `appComponentRefPromiseToken` => `APP_COMPONENT_REF_PROMISE`
  - `appComponentTypeToken` => `APP_COMPONENT`
  - `undefinedValue` => `UNDEFINED`
  - `formDirectives` => `FORM_DIRECTIVES`
  - `DOCUMENT_TOKEN` => `DOCUMENT`
  - `APP_ID_TOKEN` => `APP_ID`
  - `MAX_IN_MEMORY_ELEMENTS_PER_TEMPLATE_TOKEN` => `MAX_IN_MEMORY_ELEMENTS_PER_TEMPLATE`
  - `appBaseHrefToken` => `APP_BASE_HREF`

* renamed DI visibility flags

  - `PRIVATE` => `Visibility.Private`
  - `PUBLIC` => `Visibility.Public`
  - `PUBLIC_AND_PRIVATE` => `Visibility.PublicAndPrivate`

* renamed all "annotation" references to "metadata"

  - *Annotations => *Metadata
  - renderer.DirectiveMetadata => renderer.RendererDirectiveMetadata
  - renderer.ElementBinder => renderer.RendererElementBinder
  - impl.Directive => impl.DirectiveMetadata
  - impl.Component => impl.ComponentMetadata
  - impl.View => impl.ViewMetadata


* `IS_DARTIUM` constant is no longer exported/supported

* The HTTP package is no longer supported in Dart (use standard library apis instead)

* Remove IRequestOptions / IResponseOptions / IQueryList interfaces

* Pipe factories have been removed and Pipe names to pipe implementations are 1-to-1  instead of 1-to-*

  Before:
  <code><pre>
   class DateFormatter {
       transform(date, args){}
   }

   class DateFormatterFactory {
     supporst(obj) { return true; }
     create(cdRef) { return new DateFormatter(); }
   }
   new Pipes({date: [new DateFormatterFactory()]})
  </pre></code>

  After:
  <code><pre>
  class DateFormatter {
    transform(date, args){}
  }
  new Pipes({date: DateFormatter})
  </pre></code>


* Previously Angular called onDestroy on all pipes. Now Angular calls onDestroy only on pipes that have the onDestroy method.

* Instead of configuring pipes via a Pipes object, now you can configure them by providing the pipes property to the View decorator.

  <code><pre>
    @Pipe({
      name: 'double'
    })
    class DoublePipe {
      transform(value, args) { return value * 2; }
    }
    @View({
      template: '{{ 10 | double}}'
      pipes: [DoublePipe]
    })
    class CustomComponent {}
  </pre></code>


* The router was previously exported as ng.router in the
    angular.sfx.dev.js bundle, but now it is exported as ngRouter.

* The selector for the CSSClass directive was changed
from [class] to [ng-class]. The directive itself was
renamed from CSSClass to NgClass

### BREAKING CHANGES

*     Directives that previously injected Pipes to get iterableDiff or keyvalueDiff, now should inject IterableDiffers and KeyValueDiffers.

*     Previously, if an element had a property, Angular would update that property even if there was a directive placed on the same element with the same property. Now, the directive would have to explicitly update the native elmement by either using hostProperties or the renderer.

* View renderer used to take normalized CSS class names (ex. fooBar for foo-bar).
With this change a rendered implementation gets a calss name as specified in a
template, without any transformations / normalization. This change only affects
custom view renderers that should be updated accordingly.

### Reverts

* style(ngFor): add whitespace to `Directive` annotation ([74b311a](https://github.com/angular/angular/commit/74b311a))


### BREAKING CHANGES

* View renderer used to take normalized CSS class names (ex. fooBar for foo-bar).
With this change a rendered implementation gets a calss name as specified in a
template, without any transformations / normalization. This change only affects
custom view renderers that should be updated accordingly.

* S:
Dart applications and TypeScript applications meant to transpile to Dart must now
import `package:angular2/bootstrap.dart` instead of `package:angular2/angular2.dart`
in their bootstrap code. `package:angular2/angular2.dart` no longer export the
bootstrap function. The transformer rewrites imports of `bootstrap.dart` and calls
to `bootstrap` to `bootstrap_static.dart` and `bootstrapStatic` respectively.

### BREAKING CHANGES

*     Pipes.append has been renamed into Pipes.extend.
    Pipes.extend prepends pipe factories instead of appending them.

* S:
- shadow dom emulation no longer
  supports the `<content>` tag. Use the new `<ng-content>` instead
  (works with all shadow dom strategies).
- removed `DomRenderer.setViewRootNodes` and `AppViewManager.getComponentView`
  -> use `DomRenderer.getNativeElementSync(elementRef)` and change shadow dom directly
- the `Renderer` interface has changed:
  * `createView` now also has to support sub views
  * the notion of a container has been removed. Instead, the renderer has
    to implement methods to attach views next to elements or other views.
  * a RenderView now contains multiple RenderFragments. Fragments
    are used to move DOM nodes around.
Internal changes / design changes:
- Introduce notion of view fragments on render side
- DomProtoViews and DomViews on render side are merged,
  AppProtoViews are not merged, AppViews are partially merged
  (they share arrays with the other merged AppViews but we keep
  individual AppView instances for now).
- DomProtoViews always have a `<template>` element as root
  * needed for storing subviews
  * we have less chunks of DOM to clone now
- remove fake ElementBinder / Bound element for root text bindings
  and model them explicitly. This removes a lot of special cases we had!
- AppView shares data with nested component views
- some methods in AppViewManager (create, hydrate, dehydrate) are iterative now
  * now possible as we have all child AppViews / ElementRefs already in an array!

### BREAKING CHANGES

* S:
- host actions don't take an expression as value any more but only a method name,
  and assumes to get an array via the EventEmitter with the method arguments.
- Renderer.setElementProperty does not take `style.`/... prefixes any more.
  Use the new methods `Renderer.setElementAttribute`, ... instead
Part of #2476

* compiler will throw on binding to non-existing properties.
Till now it was possible to have a binding to a non-existing property,
ex.: `<div [foo]="exp">`. From now on this is compilation error - any
property binding needs to have at least one associated property:
eaither on an HTML element or on any directive associated with a
given element (directives' properites need to be declared using the
`properties` field in the `@Directive` / `@Component` annotation).

* - `Compiler.compile` has been removed, the only way to compile
  components dynamically is via `Compiler.compileInHost`
- `DynamicComponentLoader.loadIntoExistingLocation` has changed:
  * renamed into `loadIntoLocation`
  * will always create the host element as well
  * requires an element with a variable inside of the host component view
    next to which it will load new component.
- `DynamicComponentLoader.loadNextToExistingLocation` was renamed into
  `DynamicComponentLoader.loadNextToLocation`
- `DynamicComponentLoader.loadIntoNewLocation` is removed
  * use `DynamicComponentLoader.loadNextToLocation` instead
    and then move the view nodes
    manually around via `DomRenderer.getRootNodes()`
- `AppViewManager.{create,destroy}Free{Host,Embedded}View` was removed
  * use `AppViewManager.createViewInContainer` and then move the view nodes
    manually around via `DomRenderer.getRootNodes()`
- `Renderer.detachFreeView` was removed. Use `DomRenderer.getRootNodes()`
  to get the root nodes of a view and detach them manually.
