GNOME 3.4.1 released a few days ago, but its progress didn’t stop. The releasing cycle for 3.6 has already begun. To be honest, I don’t think that 3.4 release was quite exciting, apart maybe from GTK 3.4 that brought a lot of new features.
Some of the designing plans didn’t make on time for 3.4 and they are postponed for 3.6.
