"KDE4.2 is the next step in evolution of the new KDE branch.
Comparing to KDE 4.1.2, it makes a 'new version' impression, and
the applications are starting up a little bit faster. The bug that
prevented usage of Ctrl+C/V shortcuts for copying in Konqueror
while the 'internet' tab was present, has been fixed. Also the
automatic numbering of screenshots within ksnapshot (4.1.2 used to
forget the last snapshot name) has been fixed, too."
