Back in May, we released the Kinect for Windows SDK/Runtime v1.5 in a modular manner, to make it easier to refresh parts of the Developer Toolkit (tools, components, and samples) without the need to update the SDK (driver, runtime, and basic compilation support).
Today, we have realized that vision with the Developer Toolkit update v1.5.1. This update boosts Kinect Studio performance and stability, improves face tracking, and introduces offline documentation support. If you have already installed the SDK, simply download the new v1.5.1 Developer Toolkit Update. If you are new to Kinect for Windows, you will want to download both Kinect for Windows SDK v1.5 and Developer Toolkit v1.5.1.
