On September 12, 2017, Microsoft released the Feature Pack 2 for SharePoint Server 2016 as part of the September 2017 Public Update.
Feature packs are new product functionality that is first introduced outside the context of a product release. Microsoft released Feature Pack 1 for SharePoint 2016 last year around the same time. It will be interesting to see if Microsoft makes releasing Feature packs an annual affair going forward.
Feature pack 2 introduces full support for SharePoint Framework (SPFx) in SharePoint 2016. SharePoint Framework reached general availability in February 2017 and has been available in SharePoint Online for some time. The update contains core SPFx APIs, SPFx package deployment, and property panes. With Feature Pack 2, SharePoint 2016 can now fully support client-side SharePoint development, easy integration with SharePoint data and enhanced support for open source tooling.
This support for SPFx is significant since this will help bring many of the same capabilities that are currently available in SharePoint Online to the On-Premises version as well. It will also make it easier to implement client-side custom solutions in SharePoint 2016 which can then if needed be migrated to SharePoint Online without the need to re-architect them. This should allow organizations to better plan and future proof the implementation of custom solution on their SharePoint sites. Additional information on SPFx support for SharePoint 2016 click here.
The September 2017 Public Update also includes a security update that resolves vulnerabilities in Microsoft Office that could allow remote code execution if a user opens a specially crafted malicious Office file. The vulnerability is related to the failure of Microsoft Office to properly handle objects in memory. (For additional information refer Microsoft’s Security Tech Center Portal)
Feature Pack 2 includes Feature Pack 1 and does not need to be installed separately. Microsoft has also indicated that Feature Pack 2 will be included in all future Public Updates for SharePoint Server 2016, beginning with the September 2017 Public Update.
