No release date was announced at Data Driven but it was announced on SQL Server Blog.
SQL Server 2016 will be released for general availability on June 1st, 2016!
Take a look at the feature breakdown by edition here.
Today at 10:00am EST, Microsoft is hosting the live web-event; Data Driven.
The official session description is below but I heard a rumor that the RTM release date for SQL Server 2016 might be announced during this web-event. With 2016 RC0 already available, I am eager to see if it happens.
Set a reminder for yourself and then click here when the time comes.
If you don’t have the time to watch the web-event, I will be live blogging this event to provide details.
