A new set of updates have been released which is good news as the previous versions had been removed for download. Get the details and links to downloads from here.
As with all previous updates make sure you have installed the OCS2009-DBUpgrade otherwise you will hit problems. Make sure you stop all the OCS services and apply the updates using the ServerUpdateInstaller and the OCS2009-DBUpgrade before restarting the services to avoid any incompatibility issues. It does look like the DBUpgrade has not changed since the July update, they are both dated 1 July.
Overall the patches basically fix the problem with RGS found in the July update and a problem with server with more more than 16 cores.
No new client fixes released as yet.
