While we're growing very excited to see the KDE Plasma 2 tech preview release along with KDE Frameworks 5, which will hopefully be ready to try next month, for now there is KDE SC 4.11.3 to play with. KDE 4.11.3 was released on Tuesday and should take care of more than 120 bugs...
I really enjoy to read up the fixed bugs, but sadly the latest news announcements of KDE don't include a link to their bugtracker with the list of fixed bugs.
I took the url of an old announcement and modified it to fit it the 4.11.3 release. Click
And indeed, the list is 120 bugs long - great work KDE devs
...this is what happens when the development of new features stops..
Invalid argument is invalid. KDE 4.10.3 had over 75 bug fixes. kDE 4.10.2 had over 100 bugs fixed. They were still making new features during those releases. This is slightly better than par for the KDE Devs
