    Well, it's out already, an update to 5.1 called 5.1.0.a, that I haven't yet tried on my ESXi 5.1 vZilla build.

    But for this minor bump, I may skip it, since I have no compelling thing I'm trying to fix, and don't see any new feature I'm trying to obtain. Honestly, kind of took the wind out my sails, when I heard:

    1. It might not fix VMDirectPath issues, from a commenter here.
    2. My experience with trying to upgrade from 5.0 to 5.1 (using a boot DVD) didn't work out, with a showstopper error (that I no longer recall) that stopped me in my tracks.

    I went the fresh install route instead, simply re-importing my existing VMXs into my Inventory.

    Whatever I decide to do with my Hypervisor, I'll need to upgrade the vCenter appliance first, also now out:

    Get started with your research by reading what others are saying about the upgrade process, in these very well done articles.
