openKylin 2.0 SP2 Officially Released!
The openKylin community has officially released openKylin 2.0 SP2! This release strengthens the core foundation by continuously maintaining the Linux Kernel 6.6 LTS, deeply adapting to mainstream domestic processors including Hygon, Phytium, Zhaoxin, and Loongson, while also actively integrating the RISC-V open instruction set architecture, laying a solid and diverse compute infrastructure.
Key highlights of this release include:
● AI integration breakthrough – Built-in support for leading cloud and local LLMs including DeepSeek, Qwen, and SenseTime, establishing the foundation for an intelligent desktop interaction hub.
● Debut of the “Rock-Solid Architecture” – Incorporating three core technologies: Immutable System, KARE Compatibility Environment, and Kaiming Package Format, significantly enhancing system-level stability while ensuring broad application compatibility.
● New UKUI 4.20 Desktop – Featuring a dynamic lighting engine and AI-enhanced experience, bringing immersive interaction.
● Developer SDK upgraded to 3.0 – With 273 new APIs, deeply optimized for UKUI and the wlcom compositor.
● Broader hardware support – Compatible with over 100 terminal devices from Lenovo KaiTian, Cancon, and SpacemiT, among others.
openKylin 2.0 SP2 Feature Highlights
1. Continuous Stability with Kernel 6.6
SP2 further optimizes and enhances the 6.6 stable kernel, merging 10,000+ upstream patches and kernel-level optimizations. With support from community members, compatibility has been extended to:
● Hygon C86-4G series processors
● Phytium D3000 series
● Zhaoxin KX-7000 series
● Loongson 3A6000 series
● Glenfly Arise2 GPUs
● HAOC by Zhongguancun Laboratory
Additionally, contributions from RISC-V vendors such as UltraRISC Technology are pushing forward kernel-level adaptation based on openKylin 6.6, marking a solid step toward a unified RISC-V kernel ecosystem.
2. Major Leap in AI Capabilities
SP2 introduces an upgraded AI subsystem and AI Assistant, positioning openKylin as a comprehensive intelligent desktop hub.
● Cloud AI Models: Integrated support for DeepSeek, Baidu ERNIE Bot, Alibaba Qwen, SenseTime, iFLYTEK Spark, Baichuan, and more. Users can connect with a simple API key.
● Local AI Models: Qwen2.5-3B and others can be easily installed via the openKylin App Store, enabling offline inference for secure and efficient use.
AI Assistant Revamp
● Redesigned UI with dual display modes (window/side panel).
● Multimodal interaction: drag-and-drop for images, documents, and more.
● Customizable quick commands.
● Local document knowledge base: users can import personal files for precise Q&A.
3. Full Rollout of the “Rock-Solid Architecture”
At its core, the Rock-Solid Architecture builds an immutable system environment while providing ecosystem compatibility and management technologies. It balances system stability and security with user habits and application richness.
It is powered by three key components:
● Immutable System
● KARE Compatibility Environment
● Kaiming Package Format
Together, they effectively address upgrade and compatibility challenges common in traditional Linux distributions, enabling more secure and efficient evolution.
4. wlcom Compositor Enhancements
The Wayland SIG group continues to refine wlcom, delivering smoother performance, richer functionality, and superior stability for Wayland-based desktop experiences.
5. UKUI 4.20 Desktop Environment
Based on the design principles of lightweight perception from UKUI 4.0, UKUI 4.20 centers on four core goals: smoother interactions, smarter experiences, more personalized configurations, and a more secure foundation. It reconstructs desktop interactions across five optimization dimensions, delivering a more efficient, intelligent, and user-friendly desktop experience.
● Immersive Extension of Lightweight Visuals
UKUI 4.20 introduces a dynamic lighting engine, achieving a leap from ‘seeing clearly’ to ‘understanding intuitively,’ making the interface more visually appealing and interactions more natural.
● Smart lock screen widgets & screensavers for quick data access.
● Scene-based multimodal interactions (voice, gesture, AI prediction).
● Native AI middleware at the system layer, turning tools like search into cognitive assistants.
● 46 new animations for windows, apps, and icons, enhancing overall smoothness.
6. Built-in Screen Recording Tool
A native screen recorder is now preinstalled, supporting one-click recording, audio capture, region selection, countdown timers, and optimized performance under wlcom.
7. Native Development Empowerment
The openKylin SDK 3.0 brings:
● 15 new modules and 273 new APIs, optimized for UKUI and wlcom.
● AI SDK expansion with 20+ interfaces for intelligent app development.
● Embedded toolchain support for adapting and developing innovative smart hardware, including robots, mini smartphones, and compact computers.
● KylinCode IDE offering one-stop coding and debugging.
● Community-backed CI/CD platform for automated repo creation, builds, and image publishing.
Installation Notes
● Recommended: Fresh installation via official downloads: https://www.openkylin.top/downloads/os-en.html
● Important: Due to structural changes introduced by the Rock-Solid Architecture, upgrades from 2.0 SP1 or earlier are not supported (only SP2 Beta can upgrade). The community is actively developing a robust upgrade path—stay tuned!
