Though not officially scheduled to be announced until this afternoon (July 3), KDE 2.2beta1 was spotted on several FTP mirrors around the world early this morning.The primary goals of the release, according to KDE officials, are to "provide a preview of KDE 2.2 and to involve users and developers who wish to request/implement missing features or identify problems. Code development is currently focused on stabilizing KDE 2.2, scheduled for final release later this quarter."
The changes from 2.1.2 to this pre-release of KDE 2.2 are listed in a changelog at http://www.kde.org/announcements/changelog2_1to2_2.html. A list of FTP mirrors is at http://www.kde.org/mirrors.html.
A notable caveat from the KDE project: They don't recommend the use of gcc 3.0 in compiling the sources. According to KDE, "several known miscompilations
of production C++ code" occur with the popular GNU compiler. KDE officials say they are working with the gcc team to get the problems resolved.
