SQL Server Management Studio (SSMS) 21 is now generally available (GA)
I must admit, it's really frustrating to see that the feature you heavily use, SSIS, isn't supported in SSMS 21, but in the same breath be told that SSMS 20 is no longer supported; in one swoop I'm now only able to use an unsupported release.
In my mind, if the SSMS 21 release is going to be incomplete, then support for the prior release, SSMS 20, shouldn't be revoked until the upgrade path is complete.
Thom_A Thanks for your feedback. For clarification, when we state that SSMS 20 is no longer supported, it means that if you find a problem in SSMS 20 then we will fix in the current release (SSMS 21) and not back port it to a SSMS 20 release. We don't block customers from using SSMS 20 (or earlier releases) and we recognize that many customers (and companies) cannot immediately update to the newest release.
