# 13.0.0 (2021-11-03)
## Breaking Changes
### common
- The behavior of the `SpyLocation` used by the `RouterTestingModule` has changed
to match the behavior of browsers. It no longer emits a 'popstate' event
when `Location.go` is called. In addition, `simulateHashChange` now
triggers _both_ a `hashchange` and a `popstate` event.
Tests which use `location.go` and expect the changes to be picked up by
the `Router` should likely change to `simulateHashChange` instead.
Each test is different in what it attempts to assert so there is no
single change that works for all tests. Each test using the `SpyLocation` to
simulate browser URL changes should be evaluated on a case-by-case basis.
### core
- TypeScript versions older than 4.4.2 are no longer supported.

- NodeJS versions older than `v12.20.0` are no longer
supported due to the Angular packages using the NodeJS package exports
feature with subpath patterns.

- The `WrappedValue` class can no longer be imported from `@angular/core`,
which may result in compile errors or failures at runtime if outdated
libraries are used that are still using `WrappedValue`. The usage of
`WrappedValue` should be removed as no replacement is available.
### forms
- A new type called `FormControlStatus` has been introduced, which is a union of all possible status strings for form controls. `AbstractControl.status` has been narrowed from `string` to `FormControlStatus`, and `statusChanges` has been narrowed from `Observable<any>` to `Observable<FormControlStatus>`. Most applications should consume the new types seamlessly. Any breakage caused by this change is likely due to one of the following two problems: (1) the app is comparing `AbstractControl.status` against a string which is not a valid status; or, (2) the app is using `statusChanges` events as if they were something other than strings.
### router
- The default url serializer would previously drop
everything after and including a question mark in query parameters. That
is, for a navigation to `/path?q=hello?&other=123`, the query
params would be parsed to just `{q: 'hello'}`. This is
incorrect because the URI spec allows for question mark characers in
query data. This change will now correctly parse the params for the
above example to be `{v: 'hello?', other: '123'}`.

- Previously `null` and `undefined` inputs for `routerLink` were
equaivalent to empty string and there was no way to disable the link's
navigation.
In addition, the `href` is changed from a property `HostBinding()` to an
attribute binding (`HostBinding('attr.href')`). The effect of this
change is that `DebugElement.properties['href']` will now return the
`href` value returned by the native element which will be the full URL
rather than the internal value of the `RouterLink` `href` property.

- The router will no longer replace the browser URL when a new navigation
cancels an ongoing navigation. This often causes URL flicker and was
only in place to support some AngularJS hybrid applications. Hybrid
applications which rely on the `navigationId` being present on initial
navigations that were handled by the Angular router should instead
subscribe to `NavigationCancel` events and perform the
`location.replaceState` themselves to add `navigationId` to the Router
state.
In addition, tests which assert `urlChanges` on the `SpyLocation` may
need to be adjusted to account for the `replaceState` which is no longer
triggered.

- It is no longer possible to use `Route.loadChildren` using a string
value. The following supporting classes were removed from
`@angular/core`:

- `NgModuleFactoryLoader`
- `SystemJsNgModuleFactoryLoader`

The `@angular/router` package no longer exports these symbols:

- `SpyNgModuleFactoryLoader`
- `DeprecatedLoadChildren`

The signature of the `setupTestingRouter` function from
`@angular/core/testing` has been changed to drop its `NgModuleFactoryLoader`
parameter, as an argument for that parameter can no longer be created.
### service-worker
- The return type of `SwUpdate#activateUpdate` and `SwUpdate#checkForUpdate` changed to `Promise<boolean>`.

Although unlikely, it is possible that this change will cause TypeScript type-checking to fail in
some cases. If necessary, update your types to account for the new
return type.
## Deprecations
###
- The `renderModuleFactory` symbol in `@angular/platform-server` is no longer necessary as of Angular v13.

The `renderModuleFactory` calls can be replaced with `renderModule`.
### service-worker
- The `SwUpdate#activated` observable is deprecated.

The `SwUpdate#activated` observable only emits values as a direct response to calling
`SwUpdate#activateUpdate()` and was only useful for determining whether the call resulted in an
update or not. Now, the return value of `SwUpdate#activateUpdate()` can be used to determine the
outcome of the operation and therefore using `SwUpdate#activated` does not offer any benefit.

- The `SwUpdate#availalbe` observable is deprecated.

The new `SwUpdate#versionUpdates` observable provides the same information and more. Therefore, it
is possible to rebuild the same behavior as `SwUpdate#availalbe` using the events emitted by
`SwUpdate#versionUpdates` and filtering for `VersionReadyEvent` events.
As a result, the `SwUpdate#availalbe` observable is now redundant.
