For an detailed user-level description of new features see the following blogpost:
http://code.blender.org/index.php/2012/05/node-editing-tweaks/
TL;DR:
* Frame node gets more usable bounding-box behavior
* Node resizing has helpful mouse cursor indicators and works on all borders
* Node selection/active colors are themeable independently
* Customizable background colors for nodes (useful for frames visual
distinction).
This branch adds mostly organizational improvements to the node system by renaming the node folders and files. A couple of internal features have been added too.
Detailed information can be found on the wiki page:

On dragging a non-connected node on a noodle, it will insert it.
Functionality tweaks are possible, but it already feels non-intrusive.
Rules:
- Insertion only when a single noodle is intersecting with node.
- Default connects first matching socket type.
- If no socket match, it connects the first.
- removing duplicate chunks of code -> hide unused sockets now works
- moving some functions to the files that they get called from -> view all/home
- made duplicate a macro operator like the other places that work like this, eliminating the unnecessary transform-related property there still
- removed a few chunks of unused code
* Compo node backdrop works again.
* Compo node previews and backdrop now get correct color management
float to byte conversion.
* Compo nodes got unecessarily recalculated while moving nodes.
* Fix compo node viewer nodes not getting activated correctly.
* Main compo node preview render computations are now outside of
mutex lock, so better for multithreading.
* Tex node outputs did not work in some files loaded from 2.4.
* Change RNA updates to take into account groups that may be shared
between multiple node trees.
* Node buttons can now use the layout engine. a few simple
ones are converted. We'll keep this code in C for now,
python wouldn't help much here.
* For node buttons not using the layout engine, manually
computing the button height is not longer needed.
* Node inputs are still not RNA wrapped, would be good to
have these available as well for keying, but makesrna does
not have access to the bNodeTypes.
* Fix header menu spacing bug, and make it consistent for all headers.
* For consistency, always put menus first in the header, then any enums
to switch the type of data displayed.
* Node editor header ported to python layout. Still quite a few
operators missing to make the menus complete.
* RNA wrapped node editor, and added use_nodes property to material
and scene.
Compositor now uses threaded jobs.
- updates happen per preview node! Check this file for
fun: http://www.blender.org/bf/composite_image.blend
(any compo node could get preview!)
- had to ensure the composite data gets fully copied before
it executes thread, so editing is not frustrated.
- put back node buttons (missing init)
- added WM_jobs api call to check for running job,
illustrated with red light icon in 'use nodes' button.
- added another callback to WM_jobs, to initialize.
use this init to ensure you only do it when job really
starts.
- added an extra notifier option for WM_jobs, to signal
finished job (like redraw image view)
- fixed file read error, it copied the screen it read,
instead of using it.
- commented out annoying prints for missing ops in imagewin
