[Paraview] PV 3.4.0

[Stephen Wornom]

As newer version of PV are released, is there a file that shows what the 
new features are?

I use PV 3.4.0 and doing animations requires that I cannot change my 
screen while the animation frames are being made. There are 800 sets of 
data so it takes time during which I cannot work.
The offscreen option made help but I believe that it has been reported 
that a bug exists in 3.4.0 when using it. Has the offscreen bug been 
fixed in later releases?
Thanks,
Stephen
