Jessica Moss compares 2014 versus 2016 with respect to Business Intelligence features:
Good-bye, Business Intelligence Edition
The biggest surprise to me was the removal of the Business Intelligence edition that was initially introduced in SQL Server 2012. Truthfully, it never seemed to fit in the environments where I worked, so I guess it makes sense. Hopefully, fewer licensing options will make it easier for people to understand their licensing and pick the edition that works best for them.
2016 looks to be a great version for BI.
