Erin Stellato gives us the skinny:
We expect that the first two posts, combined with the release notes and the new Connect with SQL Server Management Studio page, provide the details you need about the changes in SSMS 20 GA. As such, the focus of this post is the roadmap for SSMS. Our roadmap is heavily influenced by the evolving capabilities of SQL Server and Azure SQL, and feedback from SSMS users. We’re currently collecting general feedback at https://aka.ms/sqlfeedback, and feedback on Copilot in SSMS at https://aka.ms/ssms-copilot-feedback. Please comment and upvote on items that you would like to see in SSMS!
With SSMS 20 now being generally available, you can download it and try it out in your own environment. Erin quells any fears that Microsoft is abandoning SSMS and covers some of the big-ticket items on the roadmap.
