I've seen past discussions revolving around the support of SQL Server 2014 and that it is not supported in SQL Developer. We are beginning to look at SQL Server 2016, is that going to be supported the same as 2014? (meaning it won't be supported?) Is there any update available as to when one or both of these versions wil be supported in SQL Developer?
support really comes about from doing migrations away from those platforms
we did fix a bug that prevented folks from being able to browse and see what's in their 14 and 16 servers...have you tried in v4.2 EA1?
