The vSphere 4 card just has a few small corrections that the readers have spotted and some updated links. Its been about 6 months since I uploaded the current version, so I can’t remember all changes, but there nothing too drastic.
The esxtop precis has had the slightly more noticeable changes. I’ve updated a couple of the thresholds to keep it in line with Duncan’s sage advice. I also added in the great tip of the keypad numbers 2, 4, 6 & 8 (see the card for what they do), as these are both useful and nice and easy to remember (so I might actually use them).
So no big changes, but if your about to print yourself off a new card, make sure its one of these new shiny ones 🙂
