DotNetNuke 5.1.1 is now available for download.  This version of DotNetNuke is a stabilization release and focused exclusively on fixing outstanding bugs which did not make the cutoff for DotNetNuke 5.1 or which were discovered after 5.1 was released.  As many people in the community are aware, DotNetNuke.com had some difficulty running DotNetNuke 5.1 under extremely heavy loads.  As a result of that experience the DotNetNuke engineering team was able to isolate several performance issues which did not show up in any of the prior testing.  Fixes for those issues were incorporated in this release along with the changes outlined below.  As usual, the complete...
