Project Server 2010: December Cumulative Update Clarification

The release of the December 2012 Cumulative Update (CU) raised a couple of questions around the SharePoint Server 2010 hotfix package and also the Project Server 2010 hotfix package so thought it worth clarifying these.

First thanks to my friends at Accenture for questioning the contents of the SharePoint Server 2010 package.  This terminology is used to reference the roll-up package for SharePoint that DOES NOT contain Project Server fixes.  However, in our article for KB 2596955 we mistakenly said that it did (we are correcting this).  The package does contain the SharePoint Foundation fixes, the PerformancePoint Services fixes and of course the SharePoint Server hotfix package (coreserver-x-none.msp).

Secondly, for Project Server you may come across two references to the December 2012 CU (or three if you include the roll up – KB 2596956).  The two are described in the roll-up as:

If you click through then the first lists around 8 fixes, and the second list just a couple, which are also included and listed in the first.

Digging a bit deeper I found that both 2553504 and 2553268 do actually contain all the fixes for the December CU and the main difference is that the second one also contains the localized MUI (Multilingual User Interface) fixes – which in this case means some updates to SQL tables to take account of new or changed terminology.  It doesn’t necessarily mean there are changes in December, as these packages are cumulative these will be updates between SP1 and now.

Best advice – if you have any MUI loaded then use 2553268 – if not then you can get away with 2553504.
