You may already be familiar with the term Cumulative Updates for other Microsoft products, and now they are about to make their appearance in the Office world. The idea of moving from individual hotfixes to a bi-monthly package of fixes is something that has benefits both for Microsoft and our customers. For Microsoft it increases efficiency in both coding and testing as it allows better planning of related fixes, and for our customers it gives a defined, predictable release pattern. The first of these cumulative updates is just about ready, and I'll post links when the KB articles are live, and also some brief notes concerning some of the fixes, but you can also look out for KB956056 (MOSS 2007), KB956057 (WSS 3.0), KB956060 (Project 2007) and KB956061 (Project Server 2007) if you happen to be reading this long after 8/29/2008. You do not require the WSS update to apply the Project Server one, but it will ensure you are up to date if you do apply it. We would also recommend that you have the recent Infrastructure Updates installed for WSS and the Office Servers (which includes Project Server) before applying the cumulative updates.
For more details of the process see the Office Sustained Engineering blog at http://blogs.technet.com/office_sustained_engineering/archive/2008/07/01/office-hotfixes-to-be-delivered-on-a-defined-schedule-in-the-form-of-cumulative-updates.aspx and also take a look at KB953878.
The KB article for the Office 2007 application suite (the regular Office clients) is already available at http://support.microsoft.com/kb/957022/, however this does not include the Project client.
