There are new iso’s / builds coming up for 3i, 3.5 and VirtualCenter:
VMware ESX 3.5 Update 1
Latest Version: 3.5 | 4/10/2008 | Build: 82663VMware VirtualCenter 2.5 Update 1
Latest Version: 2.5 | 4/10/2008 | Build: 79820VMware ESXi 3.5 Installable Update 1
Latest Version: 3.5 | 4/10/2008 | Build: 82664
Unfortunately the iso’s aren’t available for download yet and the release notes aren’t updated. I guess someone just made a mistake updating this page cause the release date isn’t for another 10 days. We will just have to wait and see.
