Cool, v3.5 final released, but...
I tried some of the documentation tutorials, but I didn't always get the
same result as shown in the documentation, especially with the
isosurface object.
The isosurface object is in some cases strangly broken, I'm quite sure I
did the things according to the tutorial, so I don't see any reason for
it to go wrong (the isosurface). Samples are here:
http://www.letwory.net/povray/
I would like to have comments on this, whether I do something wrong, or
whether it is not me, who is doing strange things. Thanks in advance.

PS. I use the window version of povray, haven't yet tried the linux
version. My system CPU: Athlon 1400MHz, with 512 MB RAM.

Take a look at the message window:
Warning: The maximum gradient found was 2.381, but max_gradient of the
isosurface was set to 1.100. The isosurface may contain holes!
Adjust max_gradient to get a proper rendering of the isosurface.
If you add max_gradient 2.4 to your (pow(x,2)+y) isosurface, it'll work.
Hmm, the sphere problem looks like a problem with PinkAlabaster.... checks
textures.inc.... Ah-ha!
(from textures.inc)
// Gray-pink alabaster or marble. Layers are scaled for a unit object
// and relative to each other.
// NOTE: This texture has very tiny dark blue specks that are often
// mistaken for rendering errors. They are not errors. Just a
// strange texture design.

"Note: 'max_gradient 4' is added to the isosurface definition here, this
will be explained later on."
Apart from that you also get the warning Tom mentions.
