Dear deepin community friends,
deepin 25.3.0 is here! This release delivers a comprehensive upgrade across three core areas: system stability and performance, experience and intelligence, and ecosystem and compatibility. From freeze protection and faster startup for Control Center and everyday applications, to UOS AI's whole-disk knowledge base and multi-agent orchestration, to the default inclusion of PC Manager, kernel updates, and coordinated support for GPU acceleration and Linyaps containers — this release further improves deepin for daily use, intelligent experiences, application compatibility, and system maintenance.
We invite deepin community members and all open-source enthusiasts to try the new version, report any issues you encounter, and share your feedback and suggestions in the comments!
🚀 Release Highlights at a Glance
● UOS AI gets a major upgrade: system-level intelligence for the Agent OS, within easy reach. Retrieve anything from your entire disk with a single sentence — every document on your computer becomes knowledge you can call on at any time. MCP, Skills, and dedicated agent capabilities now share a unified entry point, with UOS AI automatically dispatching whatever capability a task requires. The system takes the initiative, so your work moves faster.
● Significantly better stability and performance: new freeze protection keeps the taskbar, Launcher, and System Monitor responsive even when the system is severely stalled. The Control Center home page loads far faster, and commonly used applications start quickly even under heavy load, so the system stays smooth over long-term use.
● Effortless system maintenance and data protection: snapshot and restore in the Immutable System is more intuitive — snapshots can be saved to a local disk, USB drive, or portable hard drive, and restores can be started from a chosen location. PC Manager is now included in the image by default, combining detection, cleanup, and repair in one place, making system maintenance as simple as a health check.
● Stronger kernel and hardware compatibility: the default kernel is updated to 6.6.159, fixing security vulnerabilities across x86, arm64, and loong64 architectures and resolving boot issues on select devices. The higher-version kernel is updated to 6.18.56 and can be installed from Kernel Manager for better support of the latest hardware platforms.
● Continued desktop and application improvements: connected devices can be disconnected directly from the taskbar, and the shutdown animation is displayed throughout the shutdown process. Image Viewer now offers image editing, Document Viewer restores your reading position and adds three eye-care modes, Text Editor supports Markdown rendering, and Calendar supports third-party schedules.
📌 Who Should Install This Image
This image is a feature-enhancement and bug-fix release. A fresh installation is recommended for:
New devices installing deepin 25 for the first time, to get the latest features and patches right away;
Users on older deepin 25 releases that have not been updated for a long time, who would rather move to the latest version in one step with a fresh image instead of a lengthy upgrade.
Note: If your current system is running normally and kept up to date (latest version: 25.2.2), you can upgrade directly to 25.3.0 via Control Center → System Update, or with the terminal command sudo apt update && sudo apt dist-upgrade — no reinstallation needed.
Known Issues
A few minor issues that do not affect normal use are still present in this image and are being actively fixed, including:
● In Launcher group folders, the display style of folder and application names is incorrect;
● In Image Viewer, memory usage grows when adjusting the zoom level with the scroll wheel after opening an image;
● When Multitasking View is opened after the Launcher, the Launcher window appears in Multitasking View.
📥 Images and Feedback
The new images are now available on the official download channels.
If you run into any issues or have suggestions during use, please reach out through the community forum or other community channels. Every piece of feedback helps make deepin better.
Thank you to every user and community partner for your trust and support. deepin will continue to build a more stable, more intelligent, and more open-source operating system with an open mind.
That covers the main changes in deepin 25.3.0!
From system stability and performance to AI-powered experiences, the application ecosystem and compatibility, and on to the system kernel and security, this release brings many improvements you can feel directly, along with continued optimization for the stability and compatibility issues encountered in earlier use.
We encourage you to update and try the new version, and to share your experience and suggestions with the community!
