The schematics `Tree` now contains an additional `readJSON` method that supports directly
reading and parsing the content of a file as UTF-8 JSON with comment support. This avoids the need to manually
decode a Buffer, parse and handle JSON comments within a schematic when JSON content is needed.
If a file path does not exist, an exception will be thrown. While this differs from the semantics of `read`,
it helps reduce the amount of code needed for common schematic use cases. JSON parse errors will also result
in an exception being thrown with a message detailing the error.
The `_resolveReferenceString` abstract method of the `FileSystemEngineHostBase` class now has a third parameter
that provides the collection description of the schematic currently being resolved. This allows the resolver to
use any fields/options present within the collection description to adjust the resolution of the schematic. The
`encapsulation` optional field is also added to the `FileSystemCollectionDescription` type which will in the future
allow control of the `@angular/cli` VM context wrapping on an individual schematic collection basis.
The return value of `listSchematicNames` will include hidden schematics when is invoked with true as first parameter.
By default, hidden schematics are not returned.
The dev-infra tooling now directly provides public API change testing capabilities that leverage the `api-extractor` utility. These new testing capabilities are shared with framework and components.
`ts-api-guardian` has been removed as a dependency as a result.
This change allows consumers of the `NodeWorkflow` to configure the package installation task to use a package manager's `--force` option. This will be used by the `@angular/cli` update command when the update command's force option is used. This change is not intended to enable a schematic to adjust the force option.
