We changed the bootstrap order:
1. create NgZone
2. bootstrap ng1 inside NgZone and upgrade ng1 components to ng2 components.
3. bootstrap ng2 with NgZone
Note: Previous footgun behavior was: bootstrap ng2 first to extract NgZone, so that ng1 bootstrap can happen in NgZone. This meant that if ng2 bootstrap eagerly compiled a component which contained ng1 components, then we did not have complete metadata.
BREAKING CHANGE: UpgradeAdapter.addProvider are now deprecated in favor of passing in an NgModule into the adapter's constructor
Before:
```
let upgradeAdapter = new UpgradeAdapter();
upgradeAdapter.addProviders([myProvidersArray);
```
After:
```
@NgModule({
providers: myProvidersArray
})
class MyModule {}
let upgradeAdapter = new UpgradeAdapter(MyModule);
```
Currently in the `linker/compiler.ts` file, the **same identifier** is used in **two declarations**:
```typescript
export type CompilerOptions = { … }
…
export const CompilerOptions = new OpaqueToken('compilerOptions');
```
This breaks the API doc generation. I’m surprised that this was not flagged by the tsc.
The duplicate declaration was introduced in 46b212706b.
Prior to this change `ngc` would place generated files which refer
to components in the node_modules into the node_module. This is an
issue. Now all of the files are forced into a single directory
as specified in `tsconfig.json` by the `genDir` option.

Because
- `Form` is **exported** -- see line 30/31 of
`modules/@angular/forms/src/forms.ts`: i.e., <br>`export {Form} from
'./directives/form_interface'`; and
- Methods of `Form`, which are public, have an
`AbstractFormGroupDirective` parameter;
e.g.,<br>`Form.getFormGroup(dir: AbstractFormGroupDirective):
FormGroup`.
Then it makes sense for `AbstractFormGroupDirective` to be
public/exported too. In any case, if it isn't exported then the **API
docs for `Form` don't get generated properly.**
BREAKING CHANGE:
- `ApplicationRef.run` is deprecated. Use `NgZone.run` directly
- `ApplicationRef.injector` is deprecated. Inject an `Injector` or
use `NgModuleRef.injector` instead
- `ApplicationRef.zone` is deprecated. Inject `NgZone` instead.
`ApplicationRef.bootstrap` is supposed to be run inside of `ngDoBootstrap` method
of the module that is bootstrapped, and that method already runs inside of the
zone.
This class allows any provider to know and wait for the initialization of the
application. This functionality previously was tied to `ApplicationRef`.
BREAKING CHANGE:
- `ApplicationRef.waitForAsyncInitializers` is deprecated. Use
`AppInitStatus.donePromise` / `AppInitStatus.done` instead.
If a `@NgModule` has a `bootstrap` property, `PlatformRef.bootstrapModule` /
`PlatformRef.bootstrapModuleFactory` will automatically bootstrap the components
listed in there.
If such a property does not exist, `PlatformRef.bootstrapModule` /
`PlatformRef.bootstrapModuleFactory` will try to call the method `ngDoBootstrap(appRef: ApplicationRef)` on the module class.
Otherwise an error is reported.
