It's Official: openKylin 3.0 Adopts Linux 7.0 Kernel, Staying in Lockstep with Upstream Innovation
180+ Core System Libraries to Receive a Comprehensive Upgrade
If an operating system is like a building, its core libraries are the foundation. The strength of that foundation determines how high it can rise—and how long it can stand.
With openKylin 3.0, from the Linux kernel to the compiler toolchain, from the graphics stack to the networking stack, over 180 core components have been comprehensively upgraded. This represents a systematic overhaul of the system's foundational architecture.
Notably, the stable release of Linux 7.0 was announced just days ago. openKylin 3.0 has now confirmed its kernel choice, staying closely aligned with upstream development.
Upgrade Scope
High-priority components: 51 (including Linux kernel, GCC, glibc, systemd, OpenSSL, etc.)

What Users and Developers Care About
1. Application Compatibility After Upgrade
Most applications will require no modifications. Core libraries such as glibc and systemd remain backward compatible, while key dependencies like Qt and Python retain their default versions.
2. RISC-V Optimization Improvements
GCC adds support for vector cryptographic extensions (Zvk)
glibc optimizes RISC-V vector string functions
Multiple components introduce native support or compatibility fixes for RISC-V
3. Support for Legacy Hardware
The Linux 7.0 kernel maintains strong backward compatibility. However, new features introduced alongside hardware advancements will require corresponding new hardware to fully utilize.
