[vtkusers] New in VTK 5.0?

[Robert Wang]

Hi,

I'm quite new to VTK and I'm working on a project with VTK 4.2 and  
have to upgrade to 5.0.  I'd like to find out what has changed and  
improved so I can take advantage of VTK 5.0 for our application but I  
can't seem to find documentation on what actually changed.  If  
someone can let me know where I can find this information, it's  
greatly appreciated!  In particular, I'm curious to know if VTK 5.0  
can handle 4D (3D + Time) data better and if readers/writers has  
changed.

Thanks a lot!!

Rob
