Dmitry Shachnev today released Compiz 0.9.14.0. You can read release announcement here.
The biggest changes are that CCSM (CompizConfig Settings Manager) has been ported to GTK 3 and Python 3. GTK 3 change might be good news to users who still use Compiz and has HiDPI monitor.
One more interesting change is that Compiz now can load configuration from multiple files. This will allow GNOME Flashback to install its own configuration and adjust it as needed without changes in compiz. For example Unity configuration already has been moved from compiz to unity.
