NgIf syntax has been extended to support else clause to display template
when the condition is false. In addition the condition value can now
be stored in local variable, for later reuse. This is especially useful
when used with the `async` pipe.
Example:
```
<div *ngIf="userObservable | async; else loading; let user">
Hello {{user.last}}, {{user.first}}!
</div>
<template #loading>Waiting...</template>
```

BREAKING CHANGE:
These forms of providers are no longer accepted:
bind(MyClass).toFactory(...)
new Provider(MyClass, toFactory: ...)
We now only accept:
{provider: MyClass, toFactory: ...}
BREAKING CHANGE:
The 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.
Closes#9729
BREAKING CHANGE:
`Type` is now `Type<T>` which means that in most cases you have to
use `Type<any>` in place of `Type`.
We don't expect that any user applications use the `Type` type.
Prior to this fix [ngClass] would remove all dynamic classes
when destroyed. It's essential that classes are persisted such
that remove-based animations will still be stylistically correct.
This patch fixes this issue.

This contains major changes to the compiler, bootstrap of the platforms
and test environment initialization.
Main part of #10043Closes#10164
BREAKING CHANGE:
- Semantics and name of `@AppModule` (now `@NgModule`) changed quite a bit.
This is actually not breaking as `@AppModules` were not part of rc.4.
We will have detailed docs on `@NgModule` separately.
- `coreLoadAndBootstrap` and `coreBootstrap` can't be used any more (without migration support).
Use `bootstrapModule` / `bootstrapModuleFactory` instead.
- All Components listed in routes have to be part of the `declarations` of an NgModule.
Either directly on the bootstrap module / lazy loaded module, or in an NgModule imported by them.
Closes#9732
BREAKING CHANGE:
We have removed the deprecated form directives from the built-in platform directive list, so apps are not required to package forms with their app. This also makes forms friendly to offline compilation.
Instead, we have exposed three modules:
OLD API:
- `DeprecatedFormsModule`
NEW API:
- `FormsModule`
- `ReactiveFormsModule`
If you provide one of these modules, the default forms directives and providers from that module will be available to you app-wide. Note: You can provide both the `FormsModule` and the `ReactiveFormsModule` together if you like, but they are fully-functional separately.
**Before:**
```ts
import {disableDeprecatedForms, provideForms} from @angular/forms;
bootstrap(App, [
disableDeprecatedForms(),
provideForms()
]);
```
**After:**
```ts
import {DeprecatedFormsModule} from @angular/common;
bootstrap(App, {modules: [DeprecatedFormsModule] });
```
-OR-
```ts
import {FormsModule} from @angular/forms;
bootstrap(App, {modules: [FormsModule] });
```
-OR-
```ts
import {ReactiveFormsModule} from @angular/forms;
bootstrap(App, {modules: [ReactiveFormsModule] });
```
You can also choose not to provide any forms module and run your app without forms.
Or you can choose not to provide any forms module *and* provide form directives at will. This will allow you to use the deprecatedForms API for some components and not others.
```
import {FORM_DIRECTIVES, FORM_PROVIDERS} from @angular/forms;
@Component({
selector: some-comp,
directives: [FORM_DIRECTIVES],
providers: [FORM_PROVIDERS]
})
class SomeComp
```
- ts-api-guardian will now error if a new public symbol is added with a stability marker (`@stable`, `@experimental`, `@deprecated`)
- DomEventsPlugin and KeyEventsPlugin were removed from public api surface - these classes is an implementation detail
- deprecated BROWSER_PROVIDERS was removed completely
- `@angular/compiler` was removed from the ts-api-guardian check since this package shouldn't contain anything that users need to directly import
- the rest of the api surface was conservatively marked as stable or experimental
BREAKING CHANGES: DomEventsPlugin and KeyEventsPlugin previously exported from core are no longer public - these classes are implementation detail.
Previously deprecated BROWSER_PROVIDERS was completely removed from platform-browser.

Ref #9234
BREAKING CHANGE:
MockLocationStrategy was intended to be internal only and is now removed
from the `@angular/common/testing` public api.
Use `SpyLocation` from `@angular/common/testing` for location testing.
