The most notable fix that comes with the update addresses issues related to the Surface Laptop 3 automatic brightness adjustment at low brightness scenarios. The latest batch also aims to improve device stability and battery reliability.

For the owners of a Surface Laptop 3 with an Intel processor, the new firmware updates are available for devices running Windows 10 May 2019 Update, or newer. You can see the full changelog below:
