DotNetNuke 5.4.0 Released.

Products I am pleased to announce the release of DotNetNuke 5.4.0.  This release comes hot on the heals of the 5.3.0 and 5.3.1 releases and is aimed at providing ASP.Net 4.0 support to coincide with the Visual Studio 2010 launch.  This release also includes enhanced localization support and additional taxonomy support.  While less than a month has passed since the last major release, we felt it was important to support ASP.Net 4.0 very close to the platform launch which necessitated back to back major releases.  Going forward we will be returning to our regular monthly maintenance releases with another major release coming mid-summer.  As usual, you can see the full list of changes for this release on the changelog.
