Today (June 21th) the latest ConfigMgr (preview) version is released: Update 1606 for ConfigMgr Technical Preview. Update 1606 for Technical Preview is available directly in the ConfigMgr console. If you want to install ConfigMgr Technical Preview for the first time, the installation bits (currently based on Technical Preview 1603) are available on TechNet Evaluation Center.
This update includes the following improvements:
-ConfigMgr as a managed installer with Device Guard (ConfigMgr-deployed software is automatically trusted)
-Cloud Proxy Service (manage ConfigMgr clients on the Internet, with an Azure subscription)
-Grace period for application and software update deployments (give users a grace period to install required applications or software updates)
-Multiple device management points for Windows 10 Anniversary Edition devices (automatically configures an enrolled device to have more than one device management point available for use)
This update also includes new features for customers using ConfigMgr integrated with Intune (hybrid scenario):
-Device categories (automatically place devices in device collections when used in hybrid environments)
Hope that nested task sequences will be available soon too!
Just great a new (preview) version is available now!
