OpenOffice.org is publicly beta testing OpenOffice 3.0, which is not recommended for production use. General release is expected in September.
Aside from cosmetics, it will support the upcoming OpenDocument Format 1.2 and is capable of opening Office 2007 and 2008 for Mac OS X files.
It will be the first version of OpenOffice to run on Mac OS X without X11, with the look and feel of any other Aqua application.
It also includes some VBA support.
