It would seem a lot of the protocol was kept though, no? IIRC there wasn't much diff between the mssql 6.5 protocol and mssql 7 protocol. I had been working with the freetds project in 1999/2000 and spent way too much time learning about some of that, although... it was 17 years ago and details are fading!

Most of the new stuff was on ADO and ODBC drivers, if I recall correctly.

I only made use of TDS C library, because there were some DML features not yet exposed via ADO and ODBC.

I think it was backwards compat at the least but i didn't work on that area.
