Hi All :
The December 2015 release of System Center Configuration Manager is the latest product release of Configuration Manager from Microsoft. It is sometimes called System Center Configuration Manager current branch (CB). CB indicates this is a version of System Center Configuration Manager that supports incremental updates to the product. (As of December 2015, additional versions of System Center Configuration Manager are not available.) Typically, CB is not used when referring to the product, but in the future it can be an important distinction between releases of Configuration Manager.
With this release System Center Configuration Manager:
Does not use a year or product identifier in the product name, as seen with past versions like Configuration Manager 2007 or System Center 2012 Configuration Manager
Supports incremental in-product updates, also called update versions.
Incremental update versions: One of the new features for System Center Configuration Manager CB is a new in-product update process that replaces the need to learn about, locate, and download product updates from external sources. This means no more service packs or cumulative update versions to track.
Instead, when you use the System Center Configuration Manager CB, you periodically update the product using in-console updates for Configuration Manager to install new update versions. New update versions release periodically and will include product updates, and might also introduce new features you can choose to use (or not use) in your deployment. Different update versions are identified by year and month number like 1511, which identifies November 2015 (the month when System Center Configuration Manager was first released to manufacturing). Future updates, beginning in 2016, will have version names like 1602, which indicates an update that was first available in February of 2016.
These update versions are key to understanding the incremental version of your System Center Configuration Manager installation, and what features you might have available to enable in your deployment.
This blog post, I will to show you how to deployment System Center Configuration Manager CB v1511.
