The developers of KaOS have announced a new snapshot of their KDE-focused, rolling release distribution. The new snapshot, KaOS 2016.11, supports UEFI (though not Secure Boot), improves support for AMD video cards and addresses some issues with Wayland. The old Qt 4 libraries, which are no longer maintained, have been dropped. In their place, Qt 5 continues to be provided. "Most notable major updates to the base of the system are a glib2 2.50.1, FFmpeg 3.2, Linux kernel 4.8.6, systemd 232, Mesa 13.0.0, GStreamer 1.10.0, Poppler 0.48.0 and MariaDB 10.1.18. 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.

| About KaOS
|
| KaOS is a desktop Linux distribution that features the latest version of the KDE desktop environment, the Calligra office suite, and other popular software applications that use the Qt toolkit. It was inspired by Arch Linux, but the developers build their own packages which are available from in-house repositories. KaOS employs a rolling-release development model and is built exclusively for 64-bit computer systems.

Distribution Release: KaOS 2019.04 |
|
KaOS 2019.04 has been released. KaOS is a highly KDE-centric, rolling-release distribution that uses Arch's Pacman for package management tasks. The new version brings an updated toolchain together with the usual round of package and library upgrades: "A nice way of celebrating the sixth anniversary of this distribution is releasing KaOS 2019.04 with fully updated Midna theme, a new toolchain and Qt 5.12.3. As always with this rolling distribution, you will find the very latest packages for the Plasma Desktop, this includes Frameworks 5.57.0, Plasma 5.14.4 and KDE Applications 19.04.0. All built on Qt 5.12.3. A new glibc 2.29, GCC 8.3.0 and Binutils 2.32 toolchain is among the many changes to the base of the system. Updates to systemd, LLVM, MariaDB, Protobuf, MESA, Polkit and Qt required the rebuild of a large percentage of the KaOS repositories. The removal of Python2 from the KaOS repositories is ongoing. Many more packages are now build on Python3 exclusively. Highlights of KDE Applications 19.04 include an extensive re-write of Kdenlive as more than 60% of its internals have changed, improving its overall architecture."

Distribution Release: KaOS 2019.02 |
|
KaOS is an independent, rolling-release distribution featuring the Pacman package manager and the KDE Plasma desktop environment. The project's latest snapshot, KaOS 2019.02, features KDE Plasma 5.15 and LibreOffice 6.2.0. "Major updates included a move to Python 3.7 (3.7.2), Readline 8.0.0, Glib2 2.58.3, Qt 5.12.1, PHP 7.2 besides the usual full Frameworks, Plasma and KDE Applications replacements, so most systems will see 70 - 80% of their install replaced by new packages so a new ISO is more than due. Plasma 5.15 is included in this ISO. Highlights of this version include changes to the configuration interfaces, including more options for complex network configurations, integration with third-party technologies like GTK, Wayland now supports virtual desktops, and Firefox 64 can now optionally use native KDE open/save dialogs. This is a bleeding-edge functionality that is included in KaOS, it can be enabled by installing the xdg-desktop-portal and xdg-desktop-portal-kde packages and setting GTK_USE_PORTAL=1 in Firefox's .desktop file."

Distribution Release: KaOS 2018.12 |
|
A new version of KaOS, a rolling-release Linux distribution with KDE Plasma as the preferred desktop environment, has been released. Version 2018.12 comes with the very latest that the KDE and Qt projects have on offer, including Plasma 5.14.4, KDE Applications 18.12.0 and Qt 5.12.0: " KaOS is proud to announce the December release of a new stable ISO image. Two years after initially starting the move to OpenSSL 1.1 has this update become possible. All downstream libraries and applications have caught up, so the move was now smooth, without the need to have a mix of OpenSSL versions in the repositories. This move required a very large rebuild and combined with a move to Perl 5.28.1, FFmpeg 4.1, LLVM/Clang 7.0.1 and Qt 5.12.0, it is clear a new ISO was needed. The artwork saw an update to the Midna SDDM theme, gone are the QML sliding effects, instead a cleaner and simpler layout with the addition of several warnings when numlock or capslock are activated. Online Package Viewer has undergone a complete rewrite; the backend is now a very modern Go-based API, with JSON files getting the needed output, thus all loads much faster. This include the mirror status page." Read the detailed release announcement for further information. Download (SHA256): KaOS-2018.12-x86_64.iso (1,990MB, signature, pkglist). |

Distribution Release: KaOS 2018.06 |
|
KaOS is a rolling release, desktop Linux distribution that features the latest version of the KDE desktop environment. The project's newest snapshot, KaOS 2018.06, features KDE Plasma 5.13 and Croeso, a first-run wizard that helps customize the operating system. "Just days after Plasma 5.13.1 was announced can you already see it on this new release. Highlights of Plasma 5.13 include optimising startup and minimising memory usage, yielding faster time-to-desktop, better runtime performance, and less memory consumption. System Settings with KDE's Kirigami framework gives the pages a slick new look. KWin gained much-improved effects for blur and desktop switching. Wayland work continued, with the return of window rules, the use of high priority EGL Contexts, and initial support for screencasts and desktop sharing. And a tech preview of GTK global menu integration. This ISO has a complete redesign of the Midna theme for 2018. Some 2,500 new icons in use, rewritten SDDM login theme and a KaOS community selected new wallpaper (created by Jomada). Also new is KaOS' creation Croeso (Welsh for welcome) for helping with configuring a new install. It will run on the newly installed system and offers to adjust some 15 commonly used settings and replaces the formerly used, PyQt based first run wizard Kaptan."

Distribution Release: KaOS 2018.03 |
|
KaOS is an independent, rolling release distribution which focuses on providing polished desktop experience using KDE and Qt-based software. The latest snapshot of the project's installation media includes many rebuilt packages, KDE Plasma 5.12 LTS and includes the Falkon web browser. "A GCC 7.3.0, Glibc 2.26 and Binutils 2.30 based new toolchain has moved to all users. This new toolchain required a rather large rebuild of many packages. Since this also includes new systemd, Filesystem and Mkinitcpio. it is fair to say the whole base of your system will be replaced. Upstream has combined all the tiny, fully mature proto packages into one, Xorgproto package, which for KaOS users means replacing some twenty five proto packages with Xorgproto. There was also a move to Qt 5.10.1 and Plasma 5.12, thus it will be clear a new ISO is due. Falkon has replaced QupZilla as the default web browser. Falkon is a continuation of QupZilla, now developed on KDE development infrastructure." Further information cen be found in the project's release announcement.

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). |

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.
