We don't have any special information about version 10.0 of Microsoft SQL Server yet,
please visit the Microsoft SQL Server Software Informer main page.
Microsoft SQL Server 2000 has version numbers starting with 8.*, Microsoft SQL Server 2005 has version numbers starting with 9.*,
Microsoft SQL Server 2008 has version numbers starting with 10.*.
They are different products, if I have installed MS SS 2005 (9.*), doesn't make sense for me to get a warning now that 10.* is out on the wild
We don't have a download link yet, but you can find it using Google.
