26.6 "Mythos" Changes

This T2/Linux release continues to polish our flagship KDE Plasma Desktop integration, now with out-of-the-box Flatpak and Discover app store and support for more RISC architectures. For the first time, a consistently, fully reproducible, cross-compiled modern Wayland-based KDE Plasma experience is also delivered not only on x86-64 and ARM64 glibc, but also on Musl LLVM/Clang based builds and more RISC machines, such as DEC Alpha, Sgi MIPS64! Support for latest ARM64 and RISCV64 SoCs with Mesa Panfrost and PowerVR graphic support was significantly improved, too.

The result is a reproducible, modern Linux system spanning mainstream and RISC architectures alike. Combining a cutting-edge KDE Wayland desktop with T2's long-standing cross-platform support.

Of course all other desktop environments, including GNOME and Cosmic are optionally available to install, too.

The release was made possible by over 3200 changesets, over 3900 updates, nearly 260 issues fixed, over 211 packages or features added, some 41 removed, and 28 improvements by dozens of contributors.

The next step will be regular pre-compiled security and feature updates for the mainstream x86-64, arm64 and riscv64 architecutres for a easy to use and just working T2/Linux Desktop experience for every home and business use.

The user is auto logged into the KDE Desktop, and can now finally install without entering any password. If required, e.g. for console text login, The the default user and root password is "password".

Pre-built binary ISOs

Maintaining and evolving this project, along with hosting the build services, website and providing comprehensive developer resources, requires significant time and financial support.

Known Issues

Due to the nature of all cross compiled base install ISOs, gobject-introspection is not installed by default and some packages need to be natively, locally rebuilt for some advanced gnome-desktop packages.
