SharePoint Server Subscription Edition Preview has been released! This version of SharePoint offers a whole host of new features, such as Windows Server Core support, OIDC support, and an enhanced People Picker experience for SAML/OIDC which you can read below at the official documentation.
One big note I wanted to point out is the SharePoint Server 2019 Distributed Cache Crashes has been fixed! There is no need to apply this workaround as of the Preview or moving forward. This was a lot of work to resolve, so big applause to the SharePoint engineering team!
And of course, as RTM comes, I will have much much more to say on SPSE!
Congratulations to the SharePoint engineering team and all of their hard work!
