Ssis-840 Direct

I should confirm the actual versioning of SSIS. Let me think. SQL Server versions are usually denoted by the major version number, like 14.0 for SQL Server 2017, 15.0 for 2019, and 16.0 for 2022. The SSIS component might be versioned similarly or differently. However, the term SSIS 840 doesn't ring a bell. Maybe it's a typo or confusion with another system. Alternatively, SSIS is now part of Azure Data Factory or other services? Not sure. Maybe the user is referring to a specific update or service pack that's called SSIS 840, but that's not standard.
