As with every big conference, Microsoft also published a Book of News for the Build 2023 conference
Book of News: https://news.microsoft.com/build-2023-book-of-news/

Even when Build is mainly focused on a developer audience, this year Data and AI got their places in the announcement list.
My personal highlight is the public preview of Microsoft Fabric – a unified end-to-end SaaS analytics solution. Satya Nadella called it the most important milestone in the history of Microsoft data since SQL Server. I think this somehow emphasizes the importance and potential of this data suite.
Expect more blog posts & videos about Microsoft Fabric soon.
