I am pleased to announce that DotNetNuke 5.2.1 has been released.  DotNetNuke 5.2.1 is a monthly stabilization release and includes a number of fixes aimed at improving the overall stability and performance of the platform.  We continue to significantly enhance our testing effort with each release.  The 5.2.1 release benefited from an improved testing procedure that included several iterations of Load and Performance testing.  While we recognize that there is always room for improvement, we hope you’ll find that this release represents another significant step forward and further improves an already great product.   This release includes a number of fixes related to upgrade and installation scenarios.  Over the next couple of stabilization releases we will continue to focus on improving this critical part of the product.  As usual, the complete details for all of the changes can be found in the ChangeLog.
