Microsoft released SQL Server vNext (2018) – New features and enhancements in CTP 1.x


 
On 16th Nov 2016 Microsoft announced the first Community Test Preview (CTP 1.0) of SQL Server vNext that will run both on Windows & Linux. Not only Linux, but it will be supported on Docker, and macOS (via Docker) too.

For now I’m calling the vNext version as SQL Server 2018. (2018 is not called officially, I’m calling it just to avoid any confusion 🙂 )
 

This announcement was along with the release of SQL Server 2016 SP1, and the vNext version also supports features added in SQL Server 2016 SP1.
