It is not pre-release anymore. It is being used for production. It is
still maturing however. There will be more improvements in the next
year or two. Including native, fast volume rendering of AMR datasets.

Yes and no :-) Almost all of the AMR support is in VTK. However,
ParaView is the only application that is using it so far.

I would say that Chombovis has some AMR support we have not reproduced
yet. The biggest being support of edge or face centered data.
