grrrr... I was bit by the PM bug of preview going to "search results" instead of the preview, and lost my whole message!!! It's been a problem all day more than normal, but hadn't lost the message before (back button worked). I wish that would be fixed.

To recap, it never occured to me that the version was a floating-point value, not a string. The syntax does take it (I had tried other things, but not a numeric literal). I'll update my tutorial later. Any other comments on my explorations?
