Deepin 25.3.0 introduces a new anti-freeze protection mechanism, allowing users to access the taskbar, launcher, and system monitor even during severe system lags. The update also optimizes the control center loading speed and improves performance for common applications like web browsers and office suites under high-load scenarios.

The 'Xiao U' assistant has been upgraded to an Agent OS level, featuring automated task scheduling and unified access to MCP and Skills. It now supports natural language commands for reminders and periodic tasks, alongside enhanced context memory and summary capabilities for managing historical dialogues.

System maintenance is improved through an updated snapshot restoration tool that supports external storage devices like USB drives. The system logs are now capped at 5 GB to prevent disk space exhaustion, and the default kernel has been updated to 6.6.159, with an optional 6.18.56 version available for newer hardware.

The update includes extensive hardware compatibility fixes, including patches for x86, arm64, and loong64 architectures, and resolves boot issues on specific Phytium models. Desktop applications, including the image viewer, document viewer, and text editor, have received functional updates such as new editing tools and eye-protection modes.

Deepin 25.3.0 is available for X86, ARM, and LoongArch architectures. Users can perform a fresh installation via images from the official website or update their existing systems through the built-in update manager.
