Microsoft is pushing a new cumulative update to Windows 10 this afternoon. Unfortunately, details aren't yet available for this one. It's likely that the update contains some general improvements and fixes, but we'll have to wait for more details from Microsoft to be sure.
The update comes with the support number of KB3116908, and you should be able to start pulling it down via Windows Update now. Once Microsoft updates its Knowledge Base with the details of the update, we'll update this post with more information.
Update: Microsoft has provided a little more information on the Knowledge Base article for the update, giving the following generic details:
"This update includes improvements to enhance the functionality of Windows 10 Version 1511."
