Sparky 7.4, the latest update of the Sparky 7 “Orion Belt” stable line, has been released, based on Debian 12 “Bookworm”. This release includes updates to all packages from the Debian and Sparky stable repositories as of June 9, 2024. Key updates feature Linux kernels (PC: 6.1.90 LTS, ARM: 6.6.31 LTS), LibreOffice 7.4.7, KDE Plasma 5.27.5, LXQt 1.2.0, MATE 1.26, Xfce 4.18, Openbox 3.6.1, Firefox 115.11.0esr, and Thunderbird 115.11.0. Sparky 7.4 is available in various versions for amd64, i686, ARMHF, and ARM64 architectures. A last-minute error led to the reconfiguration of the Xfce and MATE ISOs, resulting in version 7.4.1. Users are advised on how to manually configure GRUB to detect other OSes. Existing Sparky 7 users can update their systems without reinstalling, and new ISO/IMG images are available for download.
