Adept 2 is for KDE 3. The last stable release was 2.1.3. Adept 3 is for KDE 4. At the end of 2008 development was discontinued, except for bug fixes, as Adept was replaced by KPackageKit for Kubuntu's 9.04 release. Adept, however, can still be installed from the Debian Testing, Debian Unstable and Ubuntu 9.04, 9.10, 10.04 and 10.10 repositories. Bug fixes are still done to Adept, but major work has been discontinued.
