Am a keen follower of Microsoft's SharePoint Blog and proud to provide this direct from the Microsoft Tech Community:

We are happy to announce the release of page management and approvals, as we disclosed at Ignite 2018.

SharePoint page authoring makes it simple to craft beautiful immersive experiences that integrate applications, data, text, media and more.  Pages are also essential for team news, which let you share impactful updates with an automated distribution engine that reaches portals, mobile, email, Microsoft Teams and more.

News pages can be highly visible, since they are automatically aggregated in hub sites, mobile apps and the SharePoint home page.  Some organizations want to standardize page templates and layouts, and institute a review process to assure that all updates are approved.

Now you can setup approval processes, based on Microsoft Flow, to ensure page review if required.  Inside the pages library, you can use the Flow pulldown menu option to create an approval process with just a few mouse clicks.

You can use the immersive demo link below to expereince page management and approvals.

Configuring approvals is optional – you can continue to publish pages without an approval step based on your governance and publication style. Page approvals will begin rolling out to targeted release in mid-December 2018.
