13.0.0-next.9 (2021-10-06)

Breaking Changes

@schematics/angular

classlist.js and web-animations-js are removed from application polyfills and uninstalled from the package. These were only needed for compatibility with Internet Explorer, which is no longer needed now that Angular only supports evergreen browsers. See: https://angular.io/guide/browser-support.

Add the following to the polyfills file for an app to re-add these packages:

import 'classlist.js';
import 'web-animations-js';

And then run:

npm install classlist.js web-animations-js --save

@angular-devkit/build-angular

Inlining of critical CSS is no longer enable by default. Users already on Angular CLI version 12 and have not opted-out from using this feature are encouraged to opt-in using the browser builder inlineCritical option.
NG_PERSISTENT_BUILD_CACHE environment variable option no longer have effect. Configure cli.cache in the workspace configuration instead.

{
  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
  "version": 1,
  "cli": {
    "cache": {
      "enabled": true,
      "path": ".custom-cache-path",
      "environment": "all"
    }
  }
  ...
}

Deprecations

@angular-devkit/build-optimizer

It's functionality has been included in @angular-devkit/build-angular so this package is no longer needed by the CLI and we will stop publishing the package soon. It has been an experimental (never hit 1.0.0) and internal (only used by Angular itself) package and should be not be used directly by others.

@angular-devkit/build-angular

NG_BUILD_CACHE environment variable option will be removed in the next major version. Configure cli.cache in the workspace configuration instead.
