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 https://github.com/angular/angular/commit/46b212706b9162c22fb1523032d7e37c9155015a.
