### 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 2. 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`

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);
```

* **core:** separate refs from vars. ([d2efac1](https://github.com/angular/angular/commit/d2efac1)), closes [#7158](https://github.com/angular/angular/issues/7158) [#8264](https://github.com/angular/angular/issues/8264)


### 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

* `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: '<'
  }
}
```

* **WebWorkers:** Fix flaky WebWorker test ([da1fcfd](https://github.com/angular/angular/commit/da1fcfd)), closes [#6851](https://github.com/angular/angular/issues/6851)

### 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.

### 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;
```

import {BrowserDomAdapter} from 'angular2/src/platform/browser/browser_adapter';
BrowserDomAdapter.makeCurrent
```
After:
```js

### 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)

### 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 2 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.

### Features

* **core:** case-sensitive camelCase templates (kebab-case removal) ([da9b46a](https://github.com/angular/angular/commit/da9b46a))


### BREAKING CHANGES

* Angular templates are now case-sensitive and use camelCase instead of kebab-case (dash-case).

  Before:

  ```
      <p *ng-if="cond">
      <my-cmp [my-prop]="exp">
      <my-cmp (my-event)="action()">
      <my-cmp [(my-prop)]="prop">

### 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`

The parser now follows the HTML5 spec more closely.
Only void and foreign elements can be self closed.

* End tags used to be tolerated for void elements with no content.
They are no more allowed so that we more closely follow the HTML5 spec.

* Before
import * as ng from 'angular2';
After
import * as core from 'angular2/core';

* Http's MockBackend is no longer exported from the `angular2/http` module. It's now available at `angular2/http/testing`

* Operators and Observables from RxJS (e.g. .map(), .toArray(), .toPromise(), etc ) now need to be explicitly imported (once per operator in your app)
  ```
  import {Observable} from 'rxjs/Observable';
  import 'rxjs/add/operator/map';
  import 'rxjs/add/observable/interval';

  Observable.interval(1000).subscribe(...);

  http.get('foos.json').map(res => res.json()).subscribe(...);
  ```

* **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.

* **dart/transform:** Restrict visibility/mutability of codegen ([45b33c5](https://github.com/angular/angular/commit/45b33c5)), closes [#5009](https://github.com/angular/angular/issues/5009)


### 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.

### 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

### BREAKING CHANGES

- TypeScript typings are now included in the distribution. If you have installed external typings

### BREAKING CHANGES

- `angular2/test_lib` is now called `angular2/testing`
  - `test_lib.js` -> `testing.js`
  - `import {...} from 'angular2/test_lib'` -> `import {...} from 'angular2/testing'`
- [()] desugaring changed:

  Before:
  ```
  <cmp [(prop)]="field"> was desugared to <cmp [prop]="field" (prop)="field=$event">
  ```
  After:
  ```
  <cmp [(prop)]="field"> is desugared to <cmp [prop]="field" (prop-change)="field=$event">
  ```

### API DEPRECATION

- "DI Binding" terminology has changed to "DI Providers" to avoid conflicts/confusion with data-binding. All commonly used apis that use "bind" or "binding" in the name still work but are deprecated and will be removed in future alpha releases. Please update your code:
  - `bind` -> `provide`
  - `@Component(bindings: ...)` -> `@Component(providers: ...)`
  - `@Component(viewBindings: ...)` -> `@Component(viewProviders: ...)`
  - `HTTP_BINDINGS` -> `HTTP_PROVIDERS`
  - `JSONP_BINDINGS` -> `JSONP_PROVIDERS`
  - `ROUTER_BINDINGS` -> `ROUTER_PROVIDERS`
  - `FORM_BINDINGS` -> `FORM_PROVIDERS`
  - `ELEMENT_PROBE_BINDINGS` -> `ELEMENT_PROBE_PROVIDERS`
  - `NoBindingError` -> `NoProviderError`
  - `AbstractBindingError` -> `AbstractProviderError`
  - `InvalidBindingError` -> `InvalidProviderError`
  - `beforeEachBindings` -> `beforeEachProviders`
  - `Binding` -> `Provider`

### 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.

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.

* **RouterLink:** use hostListeners for click ([92f1af8](https://github.com/angular/angular/commit/92f1af8)), closes [#2401](https://github.com/angular/angular/issues/2401)
* **render:** don't create property setters if not needed ([4f27611](https://github.com/angular/angular/commit/4f27611))
* **render:** don’t create an intermediate element array in renderer ([9cd510a](https://github.com/angular/angular/commit/9cd510a))
* **render:** only create `LightDom` instances if the element has children ([ca09701](https://github.com/angular/angular/commit/ca09701))
* **render:** precompute # bound text nodes and root nodes in `DomProtoView` ([24e647e](https://github.com/angular/angular/commit/24e647e))


### BREAKING CHANGES

* By default Query only queries direct children.

* Before
    @Directive({
      hostListeners: {'event': 'statement'},
      hostProperties: {'expression': 'hostProp'},
      hostAttributes: {'attr': 'value'},
      hostActions: {'action': 'statement'}
    })
After
    @Directive({
      host: {
        '(event)': 'statement',
        '[hostProp]': 'expression'  // k & v swapped
        'attr': 'value',
        '@action': 'statement'
      }
    })

* no longer cache ref
