Don't see anyone else mentioning this... I doubt Apple would post a full install 6.8GB image and then another when it goes GM later. I think both Client and Server have gone GM and are on their way to manufacturing. Looks like Apple will end-of-life the existing DVDs of Server replacing them with 9D28. This is because of significant improvements made to the upgrade process from 10.4.11 servers. Client looks like it could be 9D29. I don't know if Apple will replace the 10.5.1 (9B21) DVD. No full install image posted for Client at time of writing.
