The First System Center Semi-Annual Channel (SAC), Version 1801 Release

3 Min. Read

Introduction

You might have heard that Microsoft is switching to Semi-Annual Channel (SAC) model for Windows Server and System Center. You can read all about it here. In short, this means that every 6 months, Microsoft will release a new version with additional features for System Center and Windows Server. You will be able to update your system if you have eligible Software Assurance. These updates will fix issues, but also include new features. But before Microsoft releases the final SAC version, they will publish first a preview version for that specific update.

The First System Center Semi-Annual Channel (SAC), Version 1801 Release 1

In November 2017, Microsoft released the first SAC preview version for System Center 1711 (17=Year 2017 and 11=November), and the first production SAC for System Center is just released, version 1801 (18=Year 2018 and 01=January). But we are already in February 2018 and not in January. Yes, it’s true, Microsoft slipped in this release. Hope the next SAC release will be on time by June 2018.

What’s new in this release?

System Center, version 1801 focuses on enhancements and features for System Center Operations Manager, Virtual Machine Manager, and Data Protection Manager. Additionally, security and bug fixes, as well as support for TLS 1.2, are available for all System Center components including Orchestrator, Service Management Automation, and Service Manager.

These are the capabilities included in this release:
