* **core:** use flags in `Renderer2.setStyle` instead of booleans ([#15045](https://github.com/angular/angular/issues/15045)) ([ff71eff](https://github.com/angular/angular/commit/ff71eff))
### Features
* **common:** support `as` syntax in template/* bindings ([#15025](https://github.com/angular/angular/issues/15025)) ([c10c060](https://github.com/angular/angular/commit/c10c060)), closes [#15020](https://github.com/angular/angular/issues/15020)
* **compiler-cli:** support metadata file aliases ([0ab49d4](https://github.com/angular/angular/commit/0ab49d4))
* **core:** allow to provide multiple default testing modules ([#15054](https://github.com/angular/angular/issues/15054)) ([6c8638c](https://github.com/angular/angular/commit/6c8638c))
* **core:** expose `inputs`, `outputs` and `ngContentSelectors` on `ComponentFactory`. ([1171f91](https://github.com/angular/angular/commit/1171f91))
* **upgrade:** support multi-slot projection in upgrade/static ([#14282](https://github.com/angular/angular/issues/14282)) ([914797a](https://github.com/angular/angular/commit/914797a)), closes [#14261](https://github.com/angular/angular/issues/14261)
* **upgrade:** use `ComponentFactory.inputs/outputs/ngContentSelectors` ([a3e32fb](https://github.com/angular/angular/commit/a3e32fb))
* introduce source maps for templates ([#15011](https://github.com/angular/angular/issues/15011)) ([cdc882b](https://github.com/angular/angular/commit/cdc882b))
### BREAKING CHANGES
* Perviously, any provider that had an ngOnDestroy lifecycle hook would be created eagerly.
Now, only classes that are annotated with @Component, @Directive, @Pipe, @NgModule are eager. Providers only become eager if they are either directly or transitively injected into one of the above.
This also makes all `useValue` providers eager, which
should have no observable impact other than code size.
**EXPECTED IMPACT**:
Making providers eager was an incorrect behavior and never documented.
Also, providers that are used by a directive / pipe / ngModule stay eager.
So the impact should be rather small.
* DebugNode.source no longer returns the source location of a node.
Closes 14013
* core: (since v4 rc.1)
- `Renderer2.setStyle` no longer takes booleans but rather a
bit mask of flags.

# [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.
```
Loading...
{{ user.name }}
```
### 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.
### 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.

### Code Refactoring
* **core:** deprecate `RootRenderer` / `Renderer` ([ccb636c](https://github.com/angular/angular/commit/ccb636c))
* **core:** change abstract classes for interfaces ([#12324](https://github.com/angular/angular/issues/12324)) ([ee747f7](https://github.com/angular/angular/commit/ee747f7)), closes [#10083](https://github.com/angular/angular/issues/10083)
### 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

### BREAKING CHANGES
* common: A definition of `Iterable` is now required to correctly compile
Angular applications. Support for `Iterable` is not required at
runtime but a type definition `Iterable` must be available.
`NgFor`, and now `NgForOf`, already supports `Iterable` 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.

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

### 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` which means that in most cases you have to
use `Type` 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
```
* core: Animations that are not bound using the at-symbol
prefix using `animate-` must now be preixed using `bind-animate-`.
```html
```
* 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-` cannot be used any more on templates, use `let-`
- `var-` cannot be used any more to create a reference, use `ref-`
* 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
