SparkyLinux has unveiled its 2025.12 release, codenamed Tiamat, as a semi-rolling snapshot based on Debian Testing repositories. This version features the Linux 6.17 kernel and supports newer kernel options. It includes updated software like Firefox and Thunderbird, available in multiple desktop editions.
SparkyLinux 2025.12, known as Tiamat, arrived on December 15, 2025, drawing from the Debian Testing/Forky repositories captured on December 14, 2025. This Debian-based GNU/Linux distribution emphasizes a semi-rolling model, providing users with fresh packages while maintaining stability.
At its core, the release defaults to Linux kernel 6.17.11. Users can opt for the emerging Linux 6.18 series through the SparkyLinux repositories, alongside long-term support options like kernels 6.12 and 6.6. The bootloader has been refreshed to Grub 2.14~git20250718.0e36779, enhancing boot reliability.
Browser and email tools see updates too: Mozilla Firefox 140.5.0 ESR serves as the standard web browser, with Firefox 146 accessible via repositories. Similarly, Mozilla Thunderbird 140.5.0 ESR handles email duties by default.
Installation guidance stresses UEFI systems with an active internet connection, recommending the Calamares graphical installer for optimal results. For legacy BIOS hardware, the command-line installer is advised to avoid potential issues.
Downloads are available for 64-bit architectures in editions including LXQt 2.2, Xfce 4.20, MATE 1.26, KDE Plasma 6.5.3, MinimalGUI with Openbox, and MinimalCLI for text-mode setups. Current SparkyLinux Rolling users need not reinstall; instead, they can update by running sudo apt update && sudo apt full-upgrade in a terminal or using tools like Synaptic or Plasma Discover.
This snapshot continues SparkyLinux's tradition of lightweight, customizable options for Linux enthusiasts seeking Debian's robustness with rolling updates.
