With the official release of Ubuntu 25.04 Plucky Puffin, Ubuntu 25.04 is also launched simultaneously as a domestic "Chinese enhanced version" based on it.Ubuntu Kylin is also an open source operating system. It provides a more stable and easier-to-use Linux system for global users, especially Chinese users, by developing user-friendly desktop environments and application software with specific needs.

Ubuntu Kylin 25.04 is built based on the Linux 6.14 kernel. It has made major upgrades to the basic libraries, subsystems, and core software components, enhancing the stability and compatibility of the system and bringing a smoother and more reliable user experience. This version will be supported for 9 months.

The Ubuntu team and the Ubuntu Kylin team dedicate this version of the system to Steve Langasek, a long-time and beloved member of the Ubuntu release team.

Known as vorlon in the community, he is a software repository administrator and a member of the technical committee, SRU team, etc.

Since the first version of Ubuntu Kylin 13.04 was released in 2013, Steve has provided a lot of support in terms of software package review, modification and storage, and is very trustworthy.

On January 1, 2025, Steve unfortunately passed away due to illness. Thanks for everything he has done.

New features of Ubuntu Kylin 25.04——

2. Systemd V257.4 version

The init system has been updated to systemd v257.4 and no longer supports utmp.

Therefore, the default configuration such as /usr/lib/tmpfiles.d/systemed.conf no longer creates /run/utmp. Some tools (like "w" in procps) work with systemd-logind, but others (like "who" in coreutils) do not.

There are plans to completely remove cgroup v1 (traditional and hybrid hierarchies) in systemd v258.

Support for System V service scripts is deprecated and will be removed in v258.

3. Tool chain upgrade

GCC: Snapshot of the upcoming GCC 15

binutils: updated to 2.44

glibc: updated to 2.41

LLVM: Default version is 20

Rust: Default toolchain is 1.84

Golang: updated to 1.24

4. Software package management

APT has been updated to 3.0.

The new dependency solver is automatically used when the traditional solver cannot find a solution.

The solver can also be triggered to provide more contextual information or to evaluate performance in case of failure.

5. UKUI desktop environment

Ubuntu Kylin 25.04 adopts the UKUI desktop environment, which provides elegant visual effects, ease of use, and extensive personalization settings. Users can build a desktop layout according to their own preferences.
