The August 2010 Cumulative Update (CU) for Project and Project Server 2007 and 2010 have been released. Yesterday, Brian posted this to the Project Admin Blog. Thanks Brian. See his blog post for the detailed information this CU release.
Please note that Microsoft has changed/organized the CU packages rollup from 2007 to 2010. For Project Server 2010 it is split out between MOSS 2010 package and a MOSS 2010 plus Project Server 2010 package.
Project Server 2010 customers will want to install the MOSS and Project Server Server Rollup Package. Note this is different from 2007 where the MOSS Server Rollup contained the Project Server CU.
If you are interested the TechNet Webcast is scheduled for Tuesday, September 14, 2010 7:30 AM Pacific Time (US & Canada) TechNet Webcast: Information About Microsoft Project and Project Server Cumulative August Update.
Hope this helps. Let us know if you have any issues or questions on the MOSS 2010 or Project Server 2010 CUs.
