Is scene builder abandoned? And what about JavaFX?

[Davide Perini]

Hi all,
love JavaFX and I think that it is very productive, super awesome. 

It is pretty sad that scene builder seems so old and unsupported, scene
builder still not support spinner and many "newer" elements. Why?
Is JavaFX dead or is still active?
Since Oracle "abandon" I see no documentation of the new features
implemented.
Is there an official documentation for JavaFX now? 

Thanks
Davide
