KDE 4.8 has been released today and includes many changes, such as: multiple improvements for Dolphin, Kate, Kmail and Gwenview, adaptive power management, multiple layouts available for the ALT + TAB window switcher, Kwin optimizations and more.
KDE 4.8 also incorporates the cool Icon Tasks Plasmoid (we wrote about it a while back) in the. Using this plasmoid, you get an icons-only taskbar with support for the Unity API (quicklists, progress bars and badges), Dockmanager support and so on:
Check out the official KDE 4.8 release announcements:
Install KDE 4.8 in Kubuntu 11.10 Oneiric Ocelot
If you've installed Icon Tasks via PPA, remove it before upgrading (sudo apt-get remove plasma-widget-icon-tasks) or else you'll get an error.
The Kubuntu developers have done a great job as usual, and the latest KDE 4.8 is already available in the official Kubuntu Backports PPA, for Kubuntu 11.10 Oneiric Ocelot. Add the PPA and upgrade to KDE 4.8 using the commands below:
sudo add-apt-repository ppa:kubuntu-ppa/backports sudo apt-get update sudo apt-get dist-upgrade
Oxygen GTK3 Engine has not been packaged yet unfortunately, but you can use THIS PPA (not tested) to install it. But please note that using it, you'll also get some other unstable packages.
