KDE Community today announced the immediate availability of "Caterpillar", (a.k.a KDE 4.2 Beta 1), the first testing release of the new KDE 4.2 desktop. Caterpillar is aimed at testers and reviewers. It should provide a solid ground to report bugs that need to be tackled before KDE 4.2.0 is released. Reviewers can use this beta to get a first look at the upcoming KDE 4.2 desktop which provides significant improvements all over the desktop and applications.
