### 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.

* **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
