Microsoft has released an early preview of the group policies for the Microsoft Edge Chromium-based browser. As this is a preview, some of the policies may not have been implemented in the current Google Canary and Dev builds. Microsoft stresses that this is an early draft, policies may change between now and its final release. The group policy preview includes HTML documentation in English as well as ADMX and ADM template files that can be loaded into the Group Policy Editor. The HTML file includes both Mac and Windows policies.
