The `brs-engine` has been refactored to support an extension model, with **Roku SceneGraph** functionality moved to a separate NPM package `brs-scenegraph`. This architectural change keeps the core interpreter lean, while enabling optional extensions for **RSG** and, in the future, **SDK1** (legacy Roku apps) and **BrightSign** (digital signage platform). ## Release Changes * Refactored `brs-engine` to support extensions and moved **SceneGraph** code to a separate package by [@lvcabral](https://github.com/lvcabral) in [#760](https://github.com/lvcabral/brs-engine/pull/760) * Introduced an extension system with the `BrsExtension` interface and lifecycle hooks * Moved SceneGraph code to the `src/extensions/scenegraph/` directory * Several documentation updates to reflect the new extension model, including a new [Extensions](docs/extensions.md) document * Refactored test file imports to use top-level `brs` exports * Created the new `brs-scenegraph` package with independent build configuration Note: The **SceneGraph** functionality is on par with the last alpha release: [v2.0.0-alpha.26](https://github.com/lvcabral/brs-engine/releases/tag/v2.0.0-alpha.26). All future SceneGraph-related implementations will be made in the `brs-scenegraph` package and documented in its [CHANGELOG.md](https://github.com/lvcabral/brs-engine/blob/master/packages/scenegraph/CHANGELOG.md). **Full Changelog**: https://github.com/lvcabral/brs-engine/compare/v1.10.0...v2.0.0
