Gnome 3.2 has been released. This time around, the developers have focused on a large number of small improvements rather than big, headline features. That said, there are a couple of interesting new additions in the areas of web integration and personal data management.

Although often classed as light-weight, Xfce qualifies as a medium weight amongst the Linux front ends. It's heavier than, say, LXDE or Window Maker but it uses less resources than KDE or Gnome. However, it is a desktop environment rather than simply a window manager, and as such, it comes with a set of associated utilities.
