Breaking Changes

Minified UMD bundles are no longer included in the distributed NPM packages.

compiler-cli

Linked libraries no longer generate legacy i18n message ids. Any downstream
application that provides translations for these messages, will need to
migrate their message ids using the localize-migrate command line tool.

core

Angular no longer maintains support for node v10
Previously the ng.getDirectives function threw an error in case a
given DOM node had no Angular context associated with it (for example
if a function was called for a DOM element outside of an Angular app).
This behavior was inconsistent with other debugging utilities under ng
namespace, which handled this situation without raising an exception.
Now calling the ng.getDirectives function for such DOM nodes would
result in an empty array returned from that function.

BREAKING CHANGES

Minified UMD bundles are no longer included in the distributed NPM packages.
animations: DOM elements are now correctly removed when the root view is removed.
If you are using SSR and use the app's HTML for rendering, you will need
to ensure that you save the HTML to a variable before destorying the
app.
It is also possible that tests could be accidentally relying on the old behavior by
trying to find an element that was not removed in a previous test. If
this is the case, the failing tests should be updated to ensure they
have proper setup code which initializes elements they rely on.
common: Methods of the PlatformLocation class, namely onPopState and onHashChange,
used to return void. Now those methods return functions that can be called
to remove event handlers.
common: The methods of the HttpParams class now accept string | number | boolean
instead of string for the value of a parameter.
If you extended this class in your application,
you'll have to update the signatures of your methods to reflect these changes.
compiler-cli: Linked libraries no longer generate legacy i18n message ids. Any downstream
application that provides translations for these messages, will need to
migrate their message ids using the localize-migrate command line tool.
core: Angular no longer maintains support for node v10
core: Previously the ng.getDirectives function threw an error in case a
given DOM node had no Angular context associated with it (for example
if a function was called for a DOM element outside of an Angular app).
This behavior was inconsistent with other debugging utilities under ng
namespace, which handled this situation without raising an exception.
Now calling the ng.getDirectives function for such DOM nodes would
result in an empty array returned from that function.
core: Switching default of emitDistinctChangesOnlyDefaultValue
which changes the default behavior and may cause some applications which
rely on the incorrect behavior to fail.

emitDistinctChangesOnly flag has also been deprecated and will be
removed in a future major release.

The previous implementation would fire changes QueryList.changes.subscribe
whenever the QueryList was recomputed. This resulted in an artificially
high number of change notifications, as it is possible that recomputing
QueryList results in the same list. When the QueryList gets recomputed
is an implementation detail, and it should not be the thing that determines
how often change event should fire.

Unfortunately, fixing the behavior outright caused too many existing
applications to fail. For this reason, Angular considers this fix a
breaking fix and has introduced a flag in @ContentChildren and
@ViewChildren, that controls the behavior.

export class QueryCompWithStrictChangeEmitParent {
  @ContentChildren('foo', {
    // This option is the new default with this change.
    emitDistinctChangesOnly: true,
  })
  foos!: QueryList<any>;
}

For backward compatibility before v12
emitDistinctChangesOnlyDefaultValue was set to false. This change
changes the default to true.

core: The type of the APP_INITIALIZER token has been changed to more accurately
reflect the types of return values that are handled by Angular. Previously,
each initializer callback was typed to return any, this is now
Promise<unknown> | Observable<unknown> | void. In the unlikely event that
your application uses the Injector.get or TestBed.inject API to inject
the APP_INITIALIZER token, you may need to update the code to account for
the stricter type.

Additionally, TypeScript may report the TS2742 error if the APP_INITIALIZER
token is used in an expression of which its inferred type has to be emitted
into a .d.ts file. To workaround this, an explicit type annotation is needed,
which would typically be Provider or Provider[].

core: Minimum supported zone.js version is 0.11.4
forms: The emitEvent option was added to the following FormArray and FormGroup methods:
FormGroup.addControl
FormGroup.removeControl
FormGroup.setControl
FormArray.push
FormArray.insert
FormArray.removeAt
FormArray.setControl
FormArray.clear

If your app has custom classes that extend FormArray or FormGroup classes and override the
above-mentioned methods, you may need to update your implementation to take the new options into
account and make sure that overrides are compatible from a types perspective.

forms: Previously min and max attributes defined on the <input type="number">
were ignored by Forms module. Now presence of these attributes would
trigger min/max validation logic (in case formControl, formControlName
or ngModel directives are also present on a given input) and
corresponding form control status would reflect that.
platform-browser: XhrFactory has been moved from @angular/common/http to @angular/common.

Before

import {XhrFactory} from '@angular/common/http';

After

import {XhrFactory} from '@angular/common';

router: Strict null checks will report on fragment potentially being null.
Migration path: add null check.
router: The type of the RouterLinkActive.routerLinkActiveOptions input was
expanded to allow more fine-tuned control. Code that previously read
this property may need to be updated to account for the new type.
