Microsoft announce the public preview of SharePoint Server Subscription Edition, the next version of the on-premises SharePoint Server product.

Back in September 2020 they announced (https://bit.ly/3j8SrEy) that the next versions of Exchange Server, SharePoint Server, Skype for Business Server, and Project Server would only be available with the purchase of a subscription licence entitling organisations to support, product updates, and security patches. Project Server Subscription Edition is a part of the SharePoint Server Subscription Edition installation and thus also available for preview.
