was released one month ago and introduced multi-display support, API improvements, a simple object system, and a KDE 4 port of the kde-window-decorator (among other changes). Today though both the Compiz and Compiz Fusion communities are announcing new versions. The biggest change in Compiz 0.7.2 is wrap-able session functions added to the Compiz core, which makes it possible to perform full session save/restores within a plug-in. This minor Compiz update also has updated translations and other bug-fixes. The Compiz 0.7.2 announcement can be read on their mailing list
Meanwhile, Compiz Fusion 0.7.2 is the first Fusion release in the 0.7 development branch. The compiz-fusion-plugins-main plug-in supports saving and restoring window states through the session manager, compiz-fusion-plugins-extra adds depth to the desktop by raising windows in layers off the cube, a simple system for log-in and log-out animations, and the (unsupported) Atlantis plug-in will create an aquarium inside of a transparent cube. This release also had some improvements to the Compiz Fusion configuration manager and also introduced a new settings manager (called simple-ccsm) that is designed for users seeking a simple control panel. The Compiz Fusion 0.7.2 announcement with the complete change-log can be read on FusionComm
Compiz 0.8 and Compiz Fusion 0.8 will be the stable version of the 0.7 branches, which should be out later this year.
