Feature update

Feature updates provide new features and functionality. A new feature update may involve a major product overhaul, improvements to product architecture or a change in operating system support.

Servicing update

Servicing updates provide fixes and improvements that are essential for security and stability. These updates do not add or remove functionality; they only fix or improve existing features.


A build is the unique identifier of the deployed product that is ready for use. A build denotes a combination of feature and servicing updates. The latest build contains (in the latest servicing update) all fixes in the specified feature update.

Module update
