I just noticed that VMware released a new version of ESX 3i on the 10th of January. The current build number is “70348” and the previous was “67921”. It’s just a minor update:
EULA Update—The reissued version of ESX Server 3i Installable incorporates an updated, corrected version of the EULA.
Licensing Fix—The reissued version of ESX Server 3i Installable lets you apply appropriate host-based licenses to servers that have more than two CPUs.
