Today, Microsoft released Windows Server Insider Preview build 18975, and that's pretty much all that you need to know. There's nothing new in the changelog, as has been the case for several Server builds now. The lack of new features won't last forever, of course, since this is from the 20H1 development branch. We still have until next spring.
The build does have one known issue that's listed:
There is an issue where the App Compatibility FOD cannot be added to the OS .wim image offline using DISM /image method. After upgrade, it is necessary to reinstall the new FOD using DISM /online method.
Also available for download are build 18975 of the Server Core App Compatibility FoD Preview, and Server Language Packs. You can also grab Windows Admin Center version 1908.
This build will expire on July 31, 2020, and if you haven't gotten the hint by now with Windows Insider Preview builds, Microsoft says that you shouldn't use it in a production environment. If you want to check it out, you can download Windows Server build 18975 here.
