First, minimal test ISO is uploaded for the November stable ISO release. With this ISO a start is made to move to Limine as the bootloader. It is added as an option for UEFI installs in Calamares, not set as default yet. Plenty of testing will be needed to have Limine replace systemd-boot, but it is planned.
This ISO also tests to move to a newer systemd. 254 is now a few years old (still maintained upstream, but looks like that won't be the case much longer). Running an install on systemd 257 has been tested a while now, creating an ISO with it still fails, so the ISO has systemd 255.22, the installs will move to 257.10, if this test ISO shows no problems with that update.

As always, early test ISOs are minimal, 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, especially the move to 580 will need attention from those who have the hardware to test this driver.

Plan is to have Frameworks 6.20.0, KDE Applications 25.08.3, Plasma 6.5.3 and Linux 6.17.xx on the final ISO.

The ISO is using packages from the build & kde-next repo, but those are not enabled, so if you decide to install, make sure to add the build & kde-next repo to your pacman.conf.

Debug packages for Calamares are part of all ISOs, 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 installation log will be created in the home directory of the Live user, see ~/installation.log. It is available after the installation in the target system in /var/log/installation.log
If run from CLI, make sure to Pastebin the full output, since no installation.log will be copied then, though that log is more complete.
