What is SQL Server "Denali"? What's new?

I found a new title called **SQL Server "Denali"** in the drop down list on MSDN, but I didn't find much information about it: - What's New (this documentation is for preview only as I see) - Top 9 New Features of SQL Server "Denali" Does anyone have more detailed information about **new features** or significant **bug fixes** in this release? I'm hoping someone has used or tested it. New Features = - Sequences - Extended FILESTREAM (thanks to Eric Humphrey ) - OFFSET & FETCH (ORDER BY Clause) - Memory Manager Changes - LAG (..) and LEAD (..) .. OVER (Partition By..Order By) clause (thanks to gbn ) - Aaron's list
