```
DEPRECATION: An asynchronous before/it/after function was defined with the async keyword but also took a done callback. This is not supported and will stop working in the future. Either remove the done callback (recommended) or remove the async keyword.
```
This previously caused an `UnhandledPromiseRejection` which caused tests not to run. But Jasmine, still reported success.

With this change we provide earlier feedback in the console during a build. The setup phase can take some times if the project has a large set of dependencies.
We also move several warnings in the dev-server to an earlier phase so that we don't clutter the progress indicator.
Closes#20957
The new `ngtools/webpack` option leverages the inline resource matching syntax combined with a custom loader instead of data URIs. This provides better resource path in loaders that do not yet fully support scheme-based resource requests.
Webpack provides a method to construct a special request string that will remap a loader chain to appear to be from a specific resource path. This requires a custom loader, however, it allows rule matching to leverage the existing file extension based approach and allows providing a path to other loaders which simplifies relative request handling.
Loading the postcss-preset-env plugin includes building a mapping of unsupported
browsers by feature, which is somewhat expensive. In large compilations, this mapping
would be recomputed for each postcss-loader instance, as the plugin was recreated
for each loader invocation. By extracting the plugin instance outside of the dynamic
plugin computation, this overhead is avoided.
Since #20518, the generation of the ServiceWorker configuration has been
broken on Windows. The reason is the use of `path.posix.*` methods on
non-POSIX paths, resulting in broken paths. I.e. we ended up with
something like the following:
```js
path.posix.relative('C:\\foo', 'C:\\foo\\bar/baz');
// Expected result: `bar/baz`
// Actual result: `../C:\\foo\\bar/baz`
```
This caused the config generator to fail to find any files and thus fail
to populate the config with cacheable assets.
This commit fixes this by using platform-specific `path.*` methods for
path manipulation and manually normalizing the path separators before
returning the results.
Fixes#20894
Unsupported versions of Node.js will now show an unsupported warning when the `ng version` command is executed.
Currently Node.js major versions 12 and 14 are considered supported and tested.
Closes#20879
With this change we re-emit assets referenced in component stylesheets which where uneffected by the change that re-triggered a re-compilation.
Since we cache the the result of processed component CSS, during a re-compilation `postcss-cli-resources` plugin will not run which causes assets to be to emit. With this change we now cache the asset and re-emit them on every change.
Closes#20882
Since we rely on child compilations to compile components CSS, using the `parallel` option will cause a significant overhead because each compilation will need to spawn a worker, in this mode the worker limit is not be honored because `css-minimizer-webpack-plugin` spawn and calulators workers during the optimization phase of a compilation and not globally per instance hence causes OOM because a large number of workers to be spawned simultaneously.
Closes#20883
As reported in #20113, webpack triggers a Trusted Types violation when
lazy-loading is used. To mitigate that, enable webpack's Trusted Types
module (introduced in webpack/webpack#9856) using 'angular#bundler' as
the policy name.
The Worker constructor option for a transfer list is unfortunately not supported until Node.js 12.17. For Node.js versions prior to 12.17, a manual message post is now used to transfer the necessary initialization data to the Sass workers.
When not in a watch mode, the analyis performed by TypeScript to improve incremental type checking can be avoided by creating an abstract builder program that only wraps the underlying TypeScript program.
Performance enhancements in the upcoming TypeScript 4.3 may remove the need for this. However, TypeScript 4.3 is not yet released and is not yet supported. In addition, TypeScript 4.2 will continue to be supported throughout the v12 major even when TypeScript 4.3 is also supported.
AJV only support a single schema with the same ID, compiling schemas async can cause a race condition were multiple schemas with the same name as compiled at the same time.
Closes#20847
This reduce memory consumption during re-builds.

A pool of Workers is now used to process Sass render requests. This change allows multiple synchronous render operations to occur at the same time. Sass synchronous render operations can be up to two times faster than the asynchronous variant. The benefit will be most pronounced in applications with large amounts of Sass stylesheets.
Prior to performing the initial updated package installation during the `ng update` process, the workspace node modules directory will be removed. This cleaning increases the guarantees that the package manager will hoist packages into the correct locations and avoid peer dependency inconsistencies.
