A year and a half after launching the KDE.OpenOffice.org Integration Project, the KDE plugin with the Native Widget Framework has become part of the official OpenOffice.org development packages. Developer snapshot m118 is the first of the towards-2.0 milestones that contains it.
Please keep in mind that if you use a Linux distribution with OpenOffice.org packages based on ooo-build (Wiki), you most probably already have this. ooo-build also contains additional KDE integration features like Crystal icons for OOo (big thanks to Nuno Pinheiro and Robert Wadley!), and KDE file dialog.
