For those who want to take a chance and update to latest KDE 4.8 from KDE 4.7.4, here is how to do it.
Please note that KDE 4.8 might come with its own quirks and issues, and though updating is usually not causing any problems, you do it on your own risk.
If you are using 4.0, please open a terminal and do a safety update to 4.1 before:

sudo apt-get update
sudo apt-get install netrunner-system
sudo apt-get upgrade

If you are using 4.1 (or if you use 4.0 and have made the update above), you can proceed then with:

sudo add-apt-repository ppa:kubuntu-ppa/backports
sudo apt-get update
sudo apt-get dist-upgrade
After restart, you should be running Netrunner with a KDE 4.8.0 desktop:

Accompanying the release of Netrunner 64bit version,
we released the 4.1 version for 32bit with the following changes compared to 4.0:

- switched to Hybrid ISO
- Kernel 3.0.0.15
- KDE 4.7.4 (latest stable)
- Muon 1.2.95
- kde-gtk-config module for easy gtk2+gtk3 configuration under KDE
- several bugfixes, including system freezes during automatic update

You can get the full ISOs from our Downloads page.

If you installed Netrunner 4.0 and want to upgrade, we have added the packages for on an easy upgrade path from 4.0 -> 4.1:

Simply open a terminal and type:

sudo apt-get update
sudo apt-get install netrunner-system
sudo apt-get upgrade

If you have any questions or experience difficulties, please let us know in the forums.

Our first 64bit version of Netrunner 4 Dryland is here!
It’s also our first hybrid disk image!
It has the same features than the 32bit version with current stable KDE 4.7.4, Muon 1.2.95 (which fixes the package management issues) and GTK2+GTK3 configurator “kde-gtk-config” preinstalled.

Just grab a copy from our Downloads page and Happy Runnin’ for the weekend!

Coding for the first 64bit version of Netrunner, based on Dryland, has started this week.
Our goal is to have a RC ready by the end of the month.
