2018-01-20 NEW • Distribution Release: KaOS 2018.01 KaOS is an independent, rolling Linux distribution featuring a polished KDE Plasma desktop and the Pacman package manager. The KaOS project has released a new snapshot, KaOS 2018.01, which features fixes for the Meltdown and Spectre CPU bugs. “It is with great pleasure to present to you a first KaOS ISO for 2018. The policy is, once a first pacman -Syu becomes a major update, it is time for a new ISO so new users are not faced with a difficult first update. With the exceptional large amounts of updates the last six weeks most systems will see 70-80% of their install replaced by new packages so a new ISO is more than due. All currently available patches and fixes for the Spectre and Meltdown vulnerabilities in modern processors are included. The Linux 4.14.14 kernel is built with Retpoline enabled, latest AMD aand Intel ucodes are also built into this kernel. As always with this rolling distribution, you will find the very latest packages for the Plasma Desktop, this includes Frameworks 5.42.0, Plasma 5.11.5, KDE Applications 17.12.1. All built on Qt 5.10.0.” Further information can be found in the project’s release announcement. Download (SHA256): KaOS-2018.01-x86_64.iso (1,811MB, signature, pkglist).

2017-09-02 Distribution Release: KaOS 2017.09 KaOS is an independently developed Linux distribution which focuses on providing a polished collection of KDE/Qt-based software. The project’s latest snapshot, KaOS 2017.09, features a hardened Linux kernel with Address Space Layout Randomization (ASLR). The latest snapshot also includes the Nomad firewall utility and the Kooka scanner tool. “It has been a few years, but finally there is an up to date (Qt5/kf5 based) firewall application available again. Nomad-firewall is available on this ISO. A second scan application is added, Kooka (just ported to kf5). This application has quite a few more options than skanlite, so it is nice to be able to add a second (Qt/kf5 based) option for scanning. Krita 3.2 has the new option to use the G’MIC plugin. For that gmic-qt is added to the repositories. With this, the options to add effects to any artwork/image are sheer endless. A change in how printer packages are packaged makes it that now most printers are automatically recognized and setup, no need any longer to run any print wizard. This counts for both Live mode and installed system.” Additional changes are detailed in the project’s release announcement.

2017-04-11 Distribution Release: KaOS 2017.04 The KaOS development team has announced the release of new installation media for their KDE-focused, rolling release distribution. The new snapshot, KaOS 2017.04, features an improved installer with the ability to use GPT disk layouts on legacy BIOS systems. The project has also introduced a separate Wayland edition of the distribution for people who would like to run KDE’s Plasma desktop on a Wayland session instead of the traditional X display server. Plus, the new release features built-in VirtualBox guest modules for people who wish to run the distribution in a virtual machine. “A nice way of celebrating the fourth anniversary of this distribution is releasing KaOS 2017.04 in two flavors. This time a Plasma Wayland version is added alongside the regular X-based ISO. The Plasma Wayland version is a smaller ISO, ships with a more limited amount of applications than the regular Plasma version. At this stage, a Wayland session can only be run on free graphics drivers and the live mode (plus install) will automatically switch to a regular X-based Plasma session should the user select non-free drivers during boot-up of the Live session. A Wayland session will not run in VirtualBox.” Further information is available in the project’s release announcement.

The new snapshot, KaOS 2016.11, supports UEFI (though not Secure Boot), improves support for AMD video cards and addresses some issues with Wayland.

Linux kernel 4.8 has included support for many more ATI/Radeon cards to start using the amdgpu driver. KaOS repositories no longer provide Qt 4. It is a good three years ago that development for Qt 4 stopped, late 2015 all support including security fixes ended. Any application that has not made the transition to Qt 5 in all this time can no longer be supported in KaOS. The Linux kernel has all the needed ucode build-in for a fully automated Early Microcode update.” Additional information can be found in the project’s release announcement and release notes.
