# 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.
# 2.0.0-beta.17 (2016-04-28)

### 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 was pattern was confusing.
**After:**
- `` 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.
- `
` now becomes `
`
- `var-...` is deprecated.
- use `#` or a `ref-` outside of `*ngFor`
- for `ngFor`, use the syntax: ``

### 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

Merge cl/115454020 in G3 with this change.

* **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`):
```
///
```
(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 tag above.
Angular previously exposed typings for the entire ES6 API.

### 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;
```

* Tests are now required to use `setBaseTestProviders`
to set up. Assuming your tests are run on a browser, setup would change
as follows.
Before:
```js
// Somewhere in test setup
import {BrowserDomAdapter} from 'angular2/src/platform/browser/browser_adapter';
BrowserDomAdapter.makeCurrent
```
After:
```js

in the pubspec.yaml via the new config option
`platform_pipes`.
* `Compiler.compileInHost` now returns a `HostViewFactoryRef`
* Component view is not yet created when component constructor is called.
-> use `onInit` lifecycle callback to access the view of a component

# 2.0.0-alpha.54 (2015-12-15)
### 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.

Before
```
import {Observable} from 'angular2/core'
```
After
```

### 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')
