Microsoft holding to it's commitment of releasing SharePoint Server 2019 Preview in early summer announced the release of it on July 24th. If you haven't read what is contained in SharePoint Server 2019, please review my early blog post titled; SharePoint Server 2019: What you can expect that discusses the expected enhancements, new features and functionality, as well as what has been removed from this version of SharePoint on-premises.

In addition to SharePoint Server 2019 Preview, Project Server 2019 Preview was also released as announced by Senior Technical Product Manager of SharePoint; Bill Baer. He categorizes the enhancements and new capabilities of SharePoint Server 2019 Preview into three primary areas:

Modern, familiar and intuitive user experiences based on our investments in SharePoint Online

  • Modern interface for end users

    • Modern Lists and Libraries
    • Modern Pages
