With Microsoft SQL Server 2016, a variety of new features and enhancements to the data platform deliver breakthrough performance, advanced security, and richer, integrated reporting and analytics capabilities. In this Preview 2 ebook, we introduce three new security features: Always Encrypted, Row-Level Security, and dynamic data masking; discuss enhancements that enable you to better manage performance and storage: TempDB configuration, query store, and Stretch Database; review several improvements to Reporting Services; and also describe AlwaysOn Availability Groups, tabular enhancement, and R integration. This book is a preview edition because it’s not complete; the final edition will be available Spring of 2016.
Not comprehensive by any means but this is a good overview. I just completed a 2016 migration last weekend so I'll be using many of these features shortly.
A well written overview on the new features of SQL Server 2016. The many hybrid options it offers in combination with Microsoft Azure are interesting, but may not be possible to use for all users. Reading the book is time well spend for everyone interested in migrating to SQL Server 2016.
