Comment 2 Myriam Schweingruber 2013-04-12 07:58:29 UTC 
Since the Notification widget was replaced with a newer QML-based one, the previous versions are now considered unmaintained. There will be no more code contribution to the older versions.

Please only report bugs and wishes to the new version, available since KDE 4.10
