In SQL Server 2016 RC 2, enhancements include:
R Services setup – the setup process for R Services is much more integrated into SQL Server setup. There is no longer a need to manually download and install Microsoft R open and R Server if the SQL Server is connected to the Internet; it becomes part of the SQL Server install sequence.
SQL Server Management Studio (SSMS) – This release of SSMS features an update to the Visual Studio 2015 shell bringing enhancements such as the quick launch toolbar and improved theming support.
Mobile reports – Brand Packages will now be downloaded to the mobile report publisher from a server running RC2 and available for use in report creation. Basic mobile report content migration between servers is now supported.
These look like wrap-up tasks. It’s good to see R being integrated a little bit better; that installation series seemed a bit hacky, whereas this sounds a lot more polished.
