This is a short blog post to share that the SQL Server 2025 public preview is now available for download. At the same time, SSMS 21 has also been released and is now generally available.
The LinkedIn post by Bob Ward announcing the news can be found here: Announcing SQL Server 2025 Public Preview
In his post you’ll find a summary of the key changes coming with this new release.
Also note that the recommended version of SSMS for SQL Server 2025 is SSMS 21, which was just announced.
Here is the blog post by Erin Stellato: SQL Server Management Studio (SSMS) 21 is now generally available (GA)
There are many changes between SSMS 20 and 21, notably the fact that it’s now based on Visual Studio 2022, includes built-in Copilot integration, and finally introduces a Dark Theme.

I strongly recommend installing it, starting to use it, and providing feedback if you encounter any bugs or areas for improvement. You can do so here.
Now that SQL Server 2025 is available for testing, other blog posts written by my colleagues or myself will likely follow to showcase some of the new features.
I’m particularly thinking of the following:
- A native vector type and vector index (DiskANN)
- Optimized locking
- REST API ensupport with sp_invoke_external_rest_endpoint
- etc
