Big node groups improvement patch. Node group trees now have their own lists of input/output sockets. Those can be linked to internal nodes just like links between regular nodes. In addition group sockets can be renamed and have a defined order, which can be modified, and they can be removed again.
More details can be found in the patch tracker description (#24883) and on the code.blender.org development blog.
