== PyNodes ==

Ongoing updates to the Blender.Node Python API:

- Changed Blender.Node.node to Blender.Node.Scripted to be more specific and conform to bpython API.
- Added a Blender.Node.Socket type to be used to define node sockets in a PyNode script. Also, socket type is inferred from the value(s) passed in, instead of also being defined by the script author.
- Added attr access to input and output sockets in the __call__ method. Ex: an input socket called 'color' can be accessed as self.input.color now.

These changes break existing pynode scripts, which shouldn't be a problem yet, of course, since we're still finishing this feature for 2.46. The wiki page and sample .blends have already been updated:
