Hugh,I notice that http://sourceforge.net/projects/virtuoso/files/latest/download now points to virtuoso-opensource-7.1.0.tar.gz But as recently as the two days ago (17th 14:32 UTC), it pointed to virtuoso-opensource-6.1.8.tar.gz http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VOSIndex suggests that v6 and v7 are both receiving development time, based on their overlapping releases. 7.0.0 is considered “stable".
7.1 should be the "stable" release. It replaces 7.0.We are maintaining V6 and V7, concurrently, but as we increase V7 releases the attention to V6 will decrease, accordingly.
Could you explain the difference between v6 and v7 w.r.t. when one should be chosen over the other?
V7 includes the column-store engine, vectorized query execution, and key compression. Collectively, the aforementioned features provide performance, scalability, and overall DB compactness advantages over V6.
What about 7.1 made it “latest”, when 6.1.8 was “latest” during 7.0?
That's an admin error, it is as I've explained above :-) Kingsley
