● 开始菜单与任务栏协同优化：开始菜单提供搜索、收藏与最近使用入口，应用列表切换更直观，并支持将常用应用固定到任务栏，减少高频操作路径。
● 快捷面板优化：快捷操作面板对网络、蓝牙、声音等入口进行了集中整理，并将深色模式、投屏和飞行模式等常用开关汇集到同一界面，配合亮度与音量滑条，日常调节更加直接。
● 任务栏配置：设置中提供了更细的任务栏管理选项，支持多屏任务栏显示策略、搜索与多任务视图图标开关、托盘系统图标统一配置，以及屏幕虚拟键盘显示方式设置，便于按使用习惯进行调整。
● 背景设置体验优化：将背景预览与背景相关设置同屏显示，可更充分地利用首屏空间，方便用户浏览与切换壁纸；在浏览下方壁纸列表时，顶部预览区域仍可持续提供当前效果参考，减少频繁来回滚动。
● 字体管理：增加用户添加和查找字体功能，解决新装字体淹没在字体列表里，难以找到的问题。

Ubuntu Kylin 26.04 officially released
On April 23, 2026, the Kylin Team officially released Ubuntu Kylin 26.04, which will be supported for 9 months.
Based on the Linux 7.0 kernel, Ubuntu Kylin 26.04 brings major upgrades to core libraries, subsystems, and essential software, improving overall stability and compatibility. The desktop environment has also been upgraded to UKUI 4.20, delivering a smoother and more reliable user experience!
New Features
1. Kernel 7.0
Ubuntu Kylin 26.04 includes Linux kernel 7.0 with a series of enhancements:
● Rust language support is no longer marked as experimental.
● Improved support for Intel Core Ultra Series 3 (Panther Lake) processors.
● Optimized support for Intel Xe3 integrated graphics and integrated NPU.
● cgroupfs now mounts with nsdelegate, memory_recursiveprot, and memory_hugetlb_accounting enabled.
● Integrated the IgH EtherCAT Master module and Generic driver.
● The real-time Linux kernel is now available in the main archive for all users.
● Kernel Livepatch now supports the ARM64 architecture.
● ZFS has been updated to 2.4.1.
● DOCA-OFED 26.01 kernel modules are available for the Ubuntu generic kernel and selected derivative kernels.
2. systemd 259.5
systemd has been updated to v259.5. Compared with the default 257.9 version in 25.10, the main changes are as follows:
● The systemd service manager has been updated to version 259.5.
● Support for cgroup v1 (legacy and hybrid hierarchies) has been removed.
● Systems using cgroup v1 cannot be directly upgraded to Ubuntu Kylin 26.04.
● Ubuntu Kylin 26.04 container workloads cannot run on hosts booted with cgroup v1.
● Compatibility with traditional System V service scripts has entered the deprecation stage.
● Ubuntu Kylin 26.04 is the last release to retain compatibility with System V service scripts.
3. ToolChain update
● binutils has been updated to 2.46, and glibc to 2.43.
● Python has been updated to 3.14.3.
● LLVM now defaults to version 21.
● Rust now defaults to version 1.93.1.
● Golang has been updated to 1.26.
● OpenJDK now defaults to version 25.
4. UKUI 4.20 desktop environment
Ubuntu Kylin 26.04 continues to optimize the UKUI 4.20 desktop experience, focusing on frequently used scenarios such as the start menu, taskbar, quick settings, and personalization.
● Start menu and taskbar collaboration: the start menu provides search, favorites, and recently used entries. Application list switching is more straightforward, and frequently used apps can be pinned to the taskbar to reduce the number of steps in daily workflows.
● Quick settings panel improvements: quick settings now organize network, Bluetooth, audio, and other common controls in a more centralized way. Frequently used toggles such as dark mode, projection, and flight mode are presented together with brightness and volume sliders for faster access.
● Taskbar configuration: the settings application provides more detailed taskbar controls, including multi-display taskbar behavior, search and multitasking-view icon toggles, unified tray icon configuration, and on-screen virtual keyboard display options.
● Wallpaper settings improvements: wallpaper preview and related settings are displayed on the same screen, making it easier to browse and switch wallpapers. While browsing the wallpaper list, the preview area remains visible so users can compare changes more efficiently.
● Font management: users can add and search fonts more easily, making newly installed fonts easier to find and manage.
