I am pleased to announce the release of Web Update 2 for Autodesk Revit MEP 2012, which is available via Live Update in the product or on Autodesk.com at http://www.autodesk.com/revitmep-download.
The update can be applied to all languages of Autodesk Revit MEP 2012. We are still in the process of updating the various download pages for each language, but you can download the update from the English page in the meantime.
A list of the enhancements can be found on the download page.
