A few days behind schedule, but the highly anticipated Dynamics 365 version 9.0 for On-Premise deployments is not available for download. Preview releases have been available for a while now via the Microsoft experience web site, but on 11/2 Microsoft made this release public.
It is now available for download on the Microsoft Download center. A 90 day trial key can be used, or if you have a commercial license key you can enter that at any time (during setup or within the 90 days trial). This version includes the Reporting extensions, just like previous version. Also, be aware of supported operating systems. The system requirement mention requirement for Windows Server 2016, but just point to the Dynamics 365 Customer Engagement document site.
