- The hostname-based connection format for SQL Server when using
pyodbc will no longer specify a default "driver name", and a warning
is emitted if this is missing.  The optimal driver name for SQL Server
changes frequently and is per-platform, so hostname based connections
need to specify this. DSN-based connections are preferred.
