>I liken this to the 'Group By' situation in VFP8. How much time might we all have spent on this if MS hadn't told us about it up front. Knowing about it allowed us (at least, some of us) to avoid the situation completely. But for whatever reason, with regard to 'known' bugs, MS would rather we all bang our heads against them for a while before acknowledging that they've know about them all along.

The change in the SQL Engine's GROUP BY was not a bug at all but a change in functionality. That's why Microsoft outlined it in the docs.
