Release of the Deepin 25.3 distribution, which develops its own graphical environment

The release of the Deepin 25.3 distribution has been published, which develops its own Deepin Desktop Environment (DDE) as well as around 40 user applications, including the Deepin Music player, Deepin Movie video player, installer, and Deepin Store software center. The project is based on a group of developers from China but has transformed into an international project and supports the Russian language. The distribution repository includes over 8000 packages. All developments are distributed under the GPLv3 license. The size of the bootable ISO images is 7.2 GB (amd64, arm64, riscv64, and loongarch64).

Desktop components and applications are developed using C/C++ and Go languages. The graphical interface is built using the Qt library. A key feature of the Deepin desktop is a panel that supports multiple operating modes. In classic mode, there is a clearer separation of open windows and suggested applications to launch, along with a system tray area displayed. The efficient mode resembles Unity to some extent, mixing indicators of running programs, favorite applications, and control applets (volume/brightness settings, connected drives, clock, network status, etc.). The application launcher interface provides two modes — viewing favorite applications and navigating through the catalog of installed programs.

Among the changes:

• The UOS AI assistant has implemented a knowledge base that covers all data on the disk and added the ability to answer questions about the contents of files. Support for creating reminders and organizing periodic task execution using natural language commands has been introduced. A unified AI interface has been realized, consolidating work with MCP servers, applying skills, and performing tasks in AI agent mode.
  Improvements have been made to summarizing content and managing the interaction history with the AI assistant. Support for granting permissions to the AI agent has been added, linked to individual requests or modifiable files.
• A new protection against freezes has been added, preventing the taskbar, application menu, and System Monitor app from being blocked under significant system load, allowing for a quick force quit of problematic applications.
• The loading speed of the configurator and standard office applications has been accelerated, with their interfaces remaining responsive even under high load.
• The size of system logs is limited to 5 GB, and logging is halted if less than 5% disk space is free.
• The default kernel package has been updated to version 6.6.159. Optionally, kernel 6.18.56 is available.
• The saving and restoring of snapshots from a local disk, USB, or external storage device has been enabled. The backup strategy before installing updates has been optimized, and disk space consumption during update installations has been reduced.
• In the DDE (Deepin Desktop Environment), the ability to quickly disable Wi-Fi or Bluetooth through corresponding indicators on the taskbar has been implemented.
• Improved the login screen design and expanded support for Wayland protocols in the experimental Treeland Desktop Environment, built on a composite framework. server Treeland Window Compositor, known for its high performance of animated effects and support for gesture control on touchpads.
• The image viewer now includes an editing mode with tools such as 'crop', 'rotate', 'brush', 'shapes', 'text', 'mosaic', and 'blur'.
• The document viewer features three eye strain reduction modes (classic, green, night) and ensures recovery of the last viewed position.
• The text editor has added support for Markdown format and improved search functionality.
• The App Store has integrated settings for proxy usage. If an application installation fails, it now provides notifications with detailed information about the issue.
• The PC Manager now includes system, hardware, and network checks. Added settings for application autostart, disk cleaning operations, and options for identifying large and duplicate files.
• On systems with NVIDIA GPUs, hardware acceleration for graphics and video in Linyaps containers is supported. During installation, automatic driver selection is ensured based on the used graphics card.
