Desktop Environments Receive Comprehensive Updates
Source: Kali Linux
Kali Linux 2025.4 delivers updates across all supported desktop environments, ensuring visual consistency and improved workflow efficiency.
GNOME 49 Moves Fully to Wayland
GNOME has been upgraded to version 49, marking a significant milestone as X11 session support has been completely removed. Wayland is now the default and only supported display protocol in GNOME for Kali Linux. The transition has been designed to remain seamless, including reliable support within virtual machine environments.
The GNOME desktop has also received refreshed theming across all Kali variants. The legacy Totem video player has been replaced with Showtime, a modern GTK4-based application offering a cleaner, distraction-free viewing experience. Additionally, the application grid now organises Kali’s extensive toolset into folders that mirror the menu structure, making tool discovery easier.

A long-requested quality-of-life improvement has also arrived: users can now open a terminal using Ctrl+Alt+T or Win+T, aligning GNOME with other Kali desktop environments.
KDE Plasma 6.5 Brings Productivity Enhancements
KDE Plasma has been updated to version 6.5, combining improvements from two major releases. Key enhancements include more flexible window tiling, a redesigned screenshot tool with advanced editing features, and quick access to pinned clipboard items directly from the panel.

KRunner has also gained fuzzy matching support, allowing users to locate applications even when names are misspelled, further improving efficiency during active testing sessions.
Xfce Gains Full Color Theme Support
Source: Kali Linux
For the first time, Xfce in Kali Linux supports comprehensive color theming. Users can now customize icon themes, GTK 3 and GTK 4 applications, Qt 5 and Qt 6 programs, and window manager decorations through the Appearance application. Qt applications can be further customized using qt5ct or qt6ct, both included by default.
Wayland Support Extended to Virtual Machines
With GNOME now operating exclusively on Wayland and KDE having adopted Wayland as default since Kali Linux 2023.1, the Kali development team prioritised resolving long-standing VM compatibility gaps.
Kali Linux 2025.4 delivers full Wayland functionality across VirtualBox, VMware and QEMU, including clipboard sharing and dynamic window scaling. This removes one of the final barriers preventing widespread Wayland adoption among penetration testers who rely on virtualised environments for daily operations.

Wifipumpkin3 and Kali NetHunter Enhancements
Source: Kali Linux
While not classified as a new tool, Wifipumpkin3 receives significant attention in this release through improved NetHunter integration. Built in Python and powered by GStreamer, Wifipumpkin3 supports Evil Twin attacks, captive portal credential harvesting, DNS spoofing and traffic interception.
The NetHunter app now includes a Wifipumpkin3 preview tab with updated community phishing templates for platforms such as Facebook, Instagram, iCloud and Snapchat.
Expanded Android Support and NetHunter Improvements
Kali NetHunter has been expanded to support Android 16 on the Samsung Galaxy S10 family running LineageOS 23, including CAN bus functionality and internal wireless injection support. Android 16 support has also been added for the OnePlus Nord, while the Xiaomi Mi 9 now supports Android 15.
The NetHunter Terminal app has been fully restored, supporting all Magisk versions with interactive mode and preventing CTRL+C from closing terminal sessions. Magisk installer support now includes module installation, with kernel modules appearing directly in the Modules tab.
Live Image Distribution and Global Infrastructure Updates
Due to exceeding Cloudflare’s 5GB size limit, the Kali Live image is now distributed exclusively via BitTorrent, joining the Everything image. The Live image remains a fully functional pre-installed Kali system, compressed using xz and including the installer with a minimal package pool.
The Kali team has also expanded its mirror infrastructure, adding new mirrors in India, South Korea and the United States to improve download speeds and global accessibility.
A Release Focused on Stability and Future Readiness
Kali Linux 2025.4 represents a carefully balanced release that modernises the platform without sacrificing reliability. By completing the transition to Wayland, expanding NetHunter capabilities, introducing new tools and strengthening global infrastructure, the update reinforces Kali Linux’s role as the benchmark operating system for offensive security professionals. Fresh images are available through official channels, with weekly builds offered for users who require the latest updates ahead of the next quarterly release.
Spiritual Insight: Technology as a Medium of Divine Awareness
According to the unique spiritual knowledge of Tatvdarshi Sant Rampal Ji Maharaj, technology has not emerged by chance. He explains that the Supreme God has enabled the development of technology so that His children can recognise the True God, understand the purpose of human life, and move towards salvation.
In today’s era, information reaches millions within seconds, making it possible for true spiritual knowledge to spread beyond boundaries. Through technology, seekers can differentiate truth from illusion, gain authentic understanding of devotion, and realise that human life is meant for attaining Moksha, not merely material progress. When used with wisdom, technology becomes a divine tool guiding humanity towards its ultimate goal.
