Although there is still no official information regarding cumulative update KB3206309, released on Tuesday, Insiders have confirmed that the update, which bumps Windows 10 to 14986.1001 on both the Fast and Slow ring, revamps Windows Defender.
After installing the update, Windows 10 displays a message informing users that Windows Defender is making some improvements. More specifically, the update adds new features to Windows Defender, which will finish the antivirus’ 'new look'.
Windows Defender is making some improvements. We’re working hard on adding new features and finishing our new look, so not everything is ready quite yet. Some features you’re looking for may not be available now, which is why the previous version of Windows Defender is still available on your device.
In addition, It appears that KB3206309 is mainly a security update, which is no surprise due to the message shown when updating build 14986. Microsoft still hasn't added a knowledge base article for the cumulative update, and there's nothing in the Feedback Hub.
The Windows Insider team is taking a break for the holiday season, so there will be no new builds until 2017. However, yesterday, Microsoft did release ISOs for 14986 which are now available to download.
