The overall KB for the August Cumulative update has been updated, and now includes the KB article numbers for each individual product in the suite of clients and servers. It is titled Cumulative update packages for August 2008 for the 2007 Microsoft Office core suite applications and 2007 Microsoft Office servers and can be found at the following location.
Please note that not all of the referenced KBs have ben published yet (WSS 956057, MOSS 956056, and Project 956060 and 956061 are not published as of 9/11/08) so not all are live links - but this would be a good KB to bookmark and visit to get the latest on the details of what went in to the August CU.
I know it has delayed some of our customers from deploying this hotfix as the documents detailing the fixes have not been available and please accept my apologies - but the change in process to the cumulative updates has put a bottleneck into the KB production as so much needed documenting in one go. Hopefully by the time we release the October CU we will have ironed out this problem and will sync the release and the docs much better.
