KDE 4.1 is now available for general use. This first major update to KDE 4 brings the KDE PIM suite, various Plasma improvements, and many other features. Plasma can now replace the KDE 3 shell for most casual users. Indeed, the whole KDE 4 can now replace KDE 3, as it’s gotten so polished.
Get it while it’s hot! Packages are already available for various distributions such as Kubuntu.

KDE 4.1.1 is due on September 3rd, and KDE 4.2 will arrive at the end of January next year.
