We Solaris Desktop team integrated GNOME 2.24 into it. We also provided a lot of FOSS packages so that you don't need to build by yourself, such as XSane, Brasero, Bluefish, Songbird, Cheese and Meta Tracker .
The IPS Software Package Manager GUI is improved. NWAM (network automatic) is working better than last release. The new ZFS based time slider will save you a lot of trouble. The overall UI is also looking better.
