Microsoft has released the latest Cumulative Updates (CU) for Project and Project Server 2010 and 2007. There was a problem found in both the 2010 Server Rollup Packages which required a fix and for the patches to be rebuilt. The current guidance is that we should see it released during the week of 3/7/2010.
"As Project Server 2010 is now based on the MOSS we strongly recommend that you install the Server Rollup Packages as there're a large number of individual server packages for MOSS. There's a set of two rollup packages which contains all the fixes for SharePoint Foundation Server, MOSS and Project Server. Both Server Rollup Packages should be installed to ensure that the underlying technology that Project Server depends on is up to date.
For those accustomed to Project Server 2007 CUs, you should note that the MOSS Server Rollup Package doesn't contain the Project Server patches. You'll need to make sure that you install the MOSS + Project Server Rollup Package (the link is provided below). As in Project Server 2007, the Server Rollup Packages are much larger (~150MB each) but they'll greatly simplify your Project Server patch deployment," stated Microsoft.
