# 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.
