Release Notes

KaOS - 2019.07

KaOS is proud to announce the availability of the June release of a new stable ISO.

As always with this rolling distribution, you will find the very latest packages for the Plasma Desktop, this includes Frameworks 5.59.0, Plasma 5.16.2 and KDE Applications 19.04.2. All built on Qt 5.13.0.

Just days after Plasma 5.16.2 was announced can you already see it on this new release. Highlights of Plasma 5.16 include a completely rewritten notification system that comes with a Do Not Disturb mode, a more intelligent history which groups notifications together, and critical notifications in fullscreen apps. The Task Manager has better organized context menus, and you can configure it to move a window from a different virtual desktop to the current one with a middle click. Wayland now features drag-and-drop between XWayland and Wayland native windows. Plasma 5.16 protects your privacy, too. When any app is recording audio, a microphone icon will appear in the System Tray warning you of the fact. You can then raise or lower the volume using the wheel on your mouse, or mute and unmute the mic with a middle click.

The installer Calamares has undergone extensive changes. Among those, to avoid any legal issues, it is no longer needed to click on the NVidia license for use in non-free install mode, the License page was changed to display the needed licenses directly. The Welcome module can now do GeoIP lookups, which can help with language selections. The Partition module has additional checks for validity partition layouts.

With LibreOffice 6.2, it is now possible to supply this as a pure Qt5/kf5 application. LibreOffice has thus replaced Calligra as the default Office Application for KaOS.

KaOS' creation Croeso (Welsh for welcome) for helping with configuring a new install is included. 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. It also includes a custom Wallpaper selector, distribution info and news. It is written in QML and fits well with the Welcome application used in the Live system. The latter now includes a fully rewritten (also in QML) Installation Guide.

There is an option to verify the authenticity of downloaded KaOS ISO files through GPG signature verification, see the Download page for further details and instructions.

A KaOS specific tool to write ISO files to USB is in use. Not only does IsoWriter write to USB it also gives the option to recover your USB stick after using it for an ISO, something that regular dd copy or the previously used Imagewriter were not able to do. It includes the option to verify the written USB in comparison to the used ISO file.

Most notable major updates to the base of the system are ICU 64.2, 1.69.0 , Glib2 2.60.4, Linux 5.1.15, Krb5 1.17, Iptables 1.8.3, Xorg-server 1.20.5, Proj 6.0.0, NetworkManager 1.18.1, Poppler 0.77.0, Nano 4.3, Gstreamer 1.16.0, and Qt 5.13.0

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. Either they actually are no longer maintained or their development is ignoring the implications of building on a possible insecure toolkit.

The artwork includes custom icon themes for light and dark themes. Midna and Midna Dark both create a complete unified look from boot-up all the way through logout.

This ISO uses the CRC and finobt enabled XFS filesystem as default. CRCs enable enhanced error detection due to hardware issues, whilst the format changes also improves crash recovery algorithms and the ability of various tools to validate and repair metadata corruptions when they are found. The free inode btree does not index used inodes, allowing faster, more consistent inode allocation performance as filesystems age.

Calamares, the used installer framework, has moved to 3.2.9 series. Highlights of the changes and additions:

Octopi is becoming a very crucial part of full system maintenance for KaOS. It is not just a GUI frontend to pacman. Tools like making sure a mirror is synced before starting any update, looking at the pacman logs, an option to get a paste from a complete snapshot of all info of a system with the SysInfo tool are included. Also included are very simple ways to open files, like copy to clipboard the file path shown in Octopi. To make sure the system doesn't start using too much disk space for the pacman cache, but still giving the user the option to retain some recent packages, the cache-cleaner tool is a great addition. The built-in tool to access KCP has now a much clearer place with the addition of its own "foreign" icon in the menu-bar. When viewing package info it is now possible to click the depends of such a package. New added is the option to select custom icons for the systemtray.

For UEFI installs, KaOS uses the simple, transparent but quite powerful systemd-boot as bootloader.

To learn more about the goals and ideas behind KaOS, please read the Home, About and FAQ pages.

To avoid any misunderstanding and confusion, KaOS is not based upon, derived of, or inspired by any one particular distribution. It is completely independent, build entirely from scratch with its own repositories. To read more about this see FAQ. A rolling release distribution never has a "final" release, every ISO is merely a snapshot of the current status of the repositories. An idea what is currently available:

The ISO ships with Frameworks 5.59.0, Plasma 5.16.2, KDE Applications 19.04.2, Linux 5.1.15, Systemd 242, Kmod 26, NetworkManager 1.18.1, LibreOffice 6.2.4, Krita 4.2.2, Elisa, Xorg-Server 1.20.5, Mesa 19.0.7, Glibc 2.29, GCC 8.3.0, non-free Nvidia 430.26, Pepperflash and Python3 3.7.3 to name a few.

The package manager is Pacman 5.1.3, with the simple but powerful Octopi 0.9dev as GUI frontend. Default web browser is Qt based Falkon 3.1.0. GFXboot is included with KaOS artwork, Grub theme is Midna, Look & Feel is a KaOS exclusive version "Midna", redone for 2019.

Repositories of KaOS will stay limited in size and expect it to stay at the current maximum of about 2100-2200. A gist of what is available, besides the stable kernel there is Linux-next 5.0, LibreOffice 6.2.1, bumblebee packages, VLC, Vokoscreen, Blender, XBMC, Calibre, Sigil, Librecad, a few games like 0ad and Knights.
A limited number of the most well-known GTK applications are available, examples Firefox 67.0.4, Chrome 77, Ardour 5.12.0, Inkscape 0.92.4, GIMP 2.10.12 and Google-talkplugin
Complete language packs are available for KDE, Calligra, Firefox, LibreOffice and Thunderbird. For IM, Fcitx is available as a rather complete group.

Known issues:

To create reliable installation media, please follow the instructions from the Download page. KaOS's ISO's do not support unetbootin or rufus, and DVDs need a burn speed no higher than 4x.
