From a post by Scott Latch, Revit Architecture Product Manager, at AUGI's forums.
I am happy to announce that Autodesk has fixed the “Y2K8 bug”!
We just posted a new build (20080101_2345) of Revit Architecture, Revit Structure & Revit MEP that fixes the problem. It is still considered Web Update #3 because replacing the existing file was the fastest method of delivering it to the public. Therefore, the executable file names are the same as the previous build (20071102_2345).
We have updated the Web Update Enhancement Lists to add the following items:
Improves stability when editing groups, saving views/groups to the library or creating a new project with template set to “None”.
Improves stability when upgrading or linking a project from Autodesk Revit Building 8.1/Revit Structure 2 or older.
I would also like to inform everyone that we are only releasing this fix in the English version. Because of the time necessary to localize the update for the other languages, it would not be ready before February 1, 2008 when the problem will go away.
The Web Updates can be downloaded by going to:
RAC: Revit Architecture
RST: Revit Structure
RME: Revit MEP
Thanks to everyone for their patience while we work through this problem.
