I have no idea how far off 3.0 is in the development pipeline - but I was just thinking that it would be VERY cool if the Blender Foundation could work on arranging a professionally published book to compliment the 3.0 release when it happens.
I’m sure O’Reilly or Sams publishing would love to publish such a thing, right? I’d buy it.
I saw that on amazon before. If I remember the reviews on it were pretty mixed, which I think is why I didn’t buy it. I did download it, but personally I prefer reading a book on paper over a screen.
