Schleswig‑Holstein reports a successful migration from Microsoft Outlook/Exchange to Open‑Xchange and Thunderbird across its administration after six months of data work. Officials call it a milestone for digital sovereignty and cost control, and the next phase is moving government desktops to Linux. — Public‑sector exits from proprietary stacks signal a practical path for state‑level tech sovereignty that could reshape procurement, vendor leverage, and EU digital policy.

Wine 11.0 Released

Wine 11.0’s completion of a clean WoW64 model, NTSYNC kernel support (Linux 6.14) and improved Wayland/Vulkan integration directly reduce migration friction for organizations moving away from Windows ecosystems. This maps to the existing idea that state actors can realistically migrate public services to FOSS stacks; Wine 11.0 is a concrete technical step that increases feasibility for such sovereignty moves (actor: Linux kernel inclusion, distro packaging; evidence: unified wine binary and Wayland clipboard/IME support).
