Linux Mint released version 22.3 'Zena' officially on January 14, 2026 (downloads available from January 11), based on Ubuntu 24.04.3 LTS with Linux kernel 6.14 from Ubuntu 25.04. This point release for Cinnamon 6.6.4, MATE, and Xfce editions offers updates until April 2029, featuring new system tools, enhanced internationalization, improved file management, application updates, Cinnamon refinements, and better gaming support.
Linux Mint 22.3 Zena tracks Ubuntu LTS versions for stability, incorporating kernel 6.14 and Hardware Enablement updates (up to 6.18) for better Intel/AMD CPU/GPU/Wi-Fi compatibility. Low memory usage (under 1 GB) and reliable multi-monitor performance are maintained across editions, with a unified New Features page and comprehensive Release Notes replacing separate documents.
New tools include System Information (evolved from System Reports) with details on USB/GPU/PCI devices and firmware; System Administration (root access) for bootloader configuration; and a Thunderbolt applet for device management. To address icon issues from GNOME Adwaita changes, XApp Symbolic Icons ensure cross-desktop stability.
Application updates: Timeshift and Mint Backup support pause/resume and hidden file inclusion; Warpinator adds IPv6 and text messaging; Hypnotix hides the mouse in full-screen; Nemo file manager gains pause/resume operations, wildcard/regex search, improved thumbnails, split-screen access, and context menu templates; Update Manager shows reboot indicators.
Cinnamon 6.6.4 highlights: revamped customizable App/Mint Menu with sidebar (avatar, favorites, places, apps), taskbar notification badges, simplified virtual desktop switcher, app switching limited to visible desktops, enhanced Wayland support (keyboard layouts, input methods, Muffin window manager—X.Org default), natively rewritten on-screen keyboard, less intrusive hot corners, optimized window tiling for ultrawide/multi-monitor, per-app notification indicators, and always-on Night Light. Major internationalization improvements include rich keyboard layouts, complex script input (Chinese, Arabic), and on-screen keyboard.
Preinstalled apps like Firefox, Thunderbird, and LibreOffice are up-to-date. Gaming benefits from improved NTSYNC for Wine/Proton, supporting thousands of Steam titles—Linux Mint holds 9.27% of Linux Steam users, with over 14,000 Verified/Playable on Steam Deck. Other tweaks: 10-second shutdown timer.
Originating in 2006 as a user-friendly Ubuntu derivative, Linux Mint eases the transition from Windows. Upgrade from Mint 22 series (e.g., 22.2 Zara) via Update Manager (full update, then 'Upgrade to 22.3'); Mint 21 users should check older Nvidia hardware; Mint 20 users may need a fresh install post-backup. Download ISOs from stable/22.3 mirrors. Potential issues: VirtualBox graphics, Nvidia 470 drivers.
