Popular .Net web content management platform DotNetNuke released version 5.6 of its professional edition and enterprise edition. 

The new version includes a new Site Search feature (which includes for Boolean searches, phrase searches, relevance searches, wild cards, fuzzy searches, and groupings - based on Lucene by the way) and enhanced analytics support (through an integration with Google Analytics) which enables the tracking of sub-domains. 

DotNetNuke has also made improvements to its content approval workflow feature, the true sign in my opinion of the quality of an enterprise level CMS. This version of the CMS allows managers to configure approvals in a top-down hierarchy at the site, page, and module level.
