DotNetNuke released version 3.2.1 and 4.0.1 yesterday as stabilization releases.

From what I understand, this release includes:

• Meduim Trust issues fixed within MS MemberRole
• FreeTextBox fixes
• More documentation

I did not seeing anything concerning a fix for DNN Search Module. I will make a post here if this has been fixed...UPDATE: See Comments Here

I will be upgrading my DNN 4.0.0 installation this weekend and will post the results. For those who are interested in upgrading their DNN 3.x site, DO NOT extract the 4.x version on top of the 3.x version!
