Angular Testing Library introduces a new `zoneless` subpackage starting from version 19.2.1. It removes monkey-patching of Testing Library APIs for change detection, streamlines the API surface by replacing `componentProperties`, `componentInputs`, `componentOutputs`, and `inputs` with a single `bindings` option using Angular's binding syntax, and adds a `configureTestBed` method for manual TestBed configuration. The subpackage also improves compatibility with Vitest browser mode. It can be adopted independently without affecting existing tests.
