First, minimal test ISO is up for the November 2016 KaOS stable ISO.

As always, early test ISOs are minimal, no language packs (though Plasma 5, just the desktop, has the translations build-in), very few apps, just a web-browser, file manager, text editor, GUI package manager. The non-free nvidia drivers are included since they are a big part of what needs testing.

KaOS ISOs are not only GTK free but from now on Qt4 & KDE 4 free too.
This is as pure a Qt 5/Plasma 5 ISO as possible.

Plan is to have Frameworks 5.27.0, KDE Applications 16.08.3, Plasma 5.8.3 and Linux 4.8.x on the final ISO. If all testing goes well expect the final ISO to be released in 10-12 days.

Calamares version used is 2.4.2. Release Notes page is not updated yet, you will see the text from the September ISO.

The ISO is using packages from the build, but that repo is not enabled, so if you decide to install, make sure to add the build repo to your pacman.conf.

To help with testing:

Use Kaptan in live mode (start from the menu) and installed (will autostart), and apply as many settings changes as you like
Use Isowriter to write the test ISO to your USB stick, plan is to remove imagewriter from the repos after this test cycle
Use in live mode on as much different hardware as possible
If you have an UEFI capable system, check if the ISO boots in both UEFI and legacy BIOS mode, make sure though to turn off secure boot
test installs on real hardware are needed, not just vbox
check as many partitioning options as possible in the all new partitioning of Calamares, see if all works and is clear enough

debug packages for Calamares are part of all ISOs from now on, run Calamares with gdb if you encounter errors
provide the installation log, if you encounter any issue at all

You can start Calamares from the Welcome app, or run it with:

sudo calamares -d

The install log will be created in the home directory of the Live user, see ~/installation.log. It is available after the install in the target system in /var/log/installation.log
