Deepin 25.3 rolls out with UOS AI overhaul, freeze protection, and a new Linux kernel

The Deepin community has released version 25.3 of its Linux distribution, a wide-ranging update the developers say focuses on three pillars: system stability and performance, intelligence and user experience, and ecosystem compatibility. The most prominent addition is a substantially upgraded UOS AI, which now functions as a system-level assistant capable of retrieving information from any document stored on the user's disk with a single natural-language query. The platform also introduces a unified entry point for MCP, skills, and agent capabilities, allowing UOS AI to automatically dispatch whichever tool a given task requires.

On the reliability front, Deepin 25.3 adds new freeze protection designed to keep the taskbar, launcher, and system monitor responsive even during severe system stalls. The control center home page now loads significantly faster, and frequently used applications launch quickly under heavy load; improvements aimed at keeping the desktop smooth over long-term use. Maintenance has also been streamlined: snapshots in the immutable system feature can now be saved to a local disk, USB drive, or portable hard drive, and PC manager ships in the default image, combining detection, cleanup, and repair in a single tool.

Hardware support gets a boost as well, with the default kernel updated to 6.6.159 — patching security vulnerabilities across x86, arm64, and loong64 architectures and fixing boot issues on select devices — while users seeking support for the newest hardware can install kernel 6.18.56 via the kernel manager. Rounding out the release, the desktop sees several refinements, including taskbar device disconnection, a persistent shutdown animation, image editing in the image viewer, reading-position memory and eye-care modes in the document viewer, Markdown rendering in the text editor, and third-party schedule support in the calendar.
