[vtkusers] VTK Book - supported version querry

[Divya Rathore]

I want to purchase The Visualization Toolkit An Object-Oriented Approach To 
3D Graphics 3rd Edition Softcover textbook 
(http://www.kitware.com/products/vtktextbook.html).

I understand that version 5.0 is about to be released. Is it a right time 
for me to buy the book? Kindly suggest so that I can proceed further with 
the purchase.

warm regards,
D. Rathore
