Updating to apollo-angular v3 and angular v13 get NullInjectorError Apollo

[UchihaYuki]

I looked at source code, the decorator for Apollo class is :

@Injectable()

Shouldn't it be:

@Injectable({
  providedIn: 'root',
})

I looked in history it is:

@Injectable({
  providedIn: 'root',
})

Any reason here?

It's described in the changelog and the migration doc that ApolloModule is back and why
