*`platformXXXX()` no longer accepts providers which depend on reflection. Specifically the method signature went from `Provider[]` to `StaticProvider[]`.
Because of multiple bugs and browser inconsistencies, we have dropped the intl api in favor of data exported from the Unicode Common Locale Data Repository (CLDR). Unfortunately we had to change the i18n pipes (date, number, currency, percent) and there are some breaking changes.
- By default Angular now only contains locale data for the language `en-US`, if you set the value of `LOCALE_ID` to another locale, you will have to import new locale data for this language because we don't use the intl API anymore.
- Features:
- you don't need to use the intl polyfill for Angular anymore.
- all i18n pipes now have an additional last parameter `locale` which allows you to use a specific locale instead of the one defined in the token `LOCALE_ID` (whose default value is `en-US`).
- the new locale data extracted from CLDR are now available to developers as well and can be used through an API (which should be especially useful for library authors).
- you can still use the old pipes for now, but their names have been changed and they are no longer included in the `CommonModule`. To use them, you will have to import the `DeprecatedI18NPipesModule` after the `CommonModule` (the order is important):
- the predefined formats (`short`, `shortTime`, `shortDate`, `medium`, ...) now use the patterns given by CLDR (like it was in AngularJS) instead of the ones from the intl API. You might notice some changes, e.g. `shortDate` will be `8/15/17` instead of `8/15/2017` for `en-US`.
- the narrow version of eras is now `GGGGG` instead of `G`, the format `G` is now similar to `GG` and `GGG`.
- the narrow version of months is now `MMMMM` instead of `L`, the format `L` is now the short standalone version of months.
- the narrow version of the week day is now `EEEEE` instead of `E`, the format `E` is now similar to `EE` and `EEE`.
- the timezone `z` will now fallback to `O` and output `GMT+1` instead of the complete zone name (e.g. `Pacific Standard Time`), this is because the quantity of data required to have all the zone names in all of the existing locales is too big.
- the timezone `Z` will now output the ISO8601 basic format, e.g. `+0100`, you should now use `ZZZZ` to get `GMT+01:00`.
- new predefined formats `long`, `full`, `longTime`, `fullTime`.
- the format `yyy` is now supported, e.g. the year `52` will be `052` and the year `2017` will be `2017`.
- standalone months are now supported with the formats `L` to `LLLLL`.
- week of the year is now supported with the formats `w` and `ww`, e.g. weeks `5` and `05`.
- week of the month is now supported with the format `W`, e.g. week `3`.
- fractional seconds are now supported with the format `S` to `SSS`.
- day periods for AM/PM now supports additional formats `aa`, `aaa`, `aaaa` and `aaaaa`. The formats `a` to `aaa` are similar, while `aaaa` is the wide version if available (e.g. `ante meridiem` for `am`), or equivalent to `a` otherwise, and `aaaaa` is the narrow version (e.g. `a` for `am`).
- extra day periods are now supported with the formats `b` to `bbbbb` (and `B` to `BBBBB` for the standalone equivalents), e.g. `morning`, `noon`, `afternoon`, ....
- the short non-localized timezones are now available with the format `O` to `OOOO`. The formats `O` to `OOO` will output `GMT+1` while the format `OOOO` will be `GMT+01:00`.
- the ISO8601 basic time zones are now available with the formats `Z` to `ZZZZZ`. The formats `Z` to `ZZZ` will output `+0100`, while the format `ZZZZ` will be `GMT+01:00` and `ZZZZZ` will be `+01:00`.
- the default value for `symbolDisplay` is now `symbol` instead of `code`. This means that by default you will see `$4.99` for `en-US` instead of `USD4.99` previously.
- the second parameter of the currency pipe (`symbolDisplay`) is no longer a boolean, it now takes the values `code`, `symbol` or `symbol-narrow`. A boolean value is still valid for now, but it is deprecated and it will print a warning message in the console.
- you can now choose between `code`, `symbol` or `symbol-narrow` which gives you access to more options for some currencies (e.g. the canadian dollar with the code `CAD` has the symbol `CA$` and the symbol-narrow `$`).
- if you don't specify the number of digits to round to, the local format will be used (and it usually rounds numbers to 0 digits, instead of not rounding previously), e.g. `{{ 3.141592 | percent }}` will output `314%` for the locale `en-US` instead of `314.1592%` previously.

* **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)

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.
* **router:** do not finish bootstrap until all the routes are resolved ([#15121](https://github.com/angular/angular/issues/15121)) ([34403cd](https://github.com/angular/angular/commit/34403cd))

* **compiler:** make identifiers for generated code small to improve dev size ([5caab71](https://github.com/angular/angular/commit/5caab71f7dc64b10f3544b2a3b2650e1666adbf1))
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.
We’ve made changes under the 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.
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.
<div*ngIf="userObservable | async; else loading; let user">
{{ user.name }}
</div>
```
### 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.
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.
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
*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';`.
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.

### 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)).

### 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)).

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