While the KB3116908 doesn’t include new features, it does brings Windows 10 version 1511 to build 10586.17, as you can see in the image below.

As always, the December 2, 2015, update for Windows 10 is cumulative, therefore, the package includes all previously released fixes. If you have installed previous updates, only the new fixes that are contained in this package will be downloaded and installed to your computer. KB3116908 is available immediately through Windows Update, the cumulative update will download and install automatically, but you can always go to Settings > Update & security and manually force the download. Furthermore, the update is available for everyone, including for Windows Insiders and non-Insiders.
