>The reason for my, let's call it doubt, was Dmitry's version number which was 6 something. Over the years have worked with several MS SQL ODBC drivers, but I can't remember any version number below 10. That made me think that he meant for instance MySql.

You wouldn't believe... some very rich customers stayed with SQL server 2000 (!) well into year 2016 or so. So we had to stay compatible with that driver for a long time, just in case. And it wasn't the age of the SQL that forced them to upgrade, it was the hardware.
