Yeah. this makes it pretty clear.
And I'm beginning to disbelieve my memory of the additional features in 3.38. I was doing a web search for software to allow me to do some in-home surveillance with one of my web cams, and I could have been confusing Cheese features with another application's features.
This surveillance project exceeded its value to me about an hour ago, so I'm going to move on now. Thanks again for helping me to figure out the oddness in the versioning. Apologies for the distraction!
