Microsoft announced the first release candidate (a.k.a. RC1) for SQL Server 2017 on Monday, July 17th. Release candidates are not a final and finished product, but they are feature complete. No new features are expected after Microsoft moves into the RC phase, only adding polish (for example, brushing up the documentation and UI) and performance to the existing feature set. The full product release is planned for some time in the second half of 2017.
