Kali Linux 2026.4
The Offensive security team has done major changes with Kali Linux 2026.4, and they have addressed some long-time issues. Here are some notable updates and bugs fixes.
New Desktop Environment and GTK3 Theme
With the update, developers planned to address the performance issues, by removing overhead features that are not useful for a distribution like Kali and the fractured user experience, if you are using a high-end laptop or using a Raspberry Pi the user experience be the same. Another thing is the modern look than the traditional one.
So to address the issues they committed to a lightweight one that runs under all the levels of Kali installs and handles user requests without compromising user experience.
If you don’t like the new UI, you can still have the option to switch to the Gnome build.
Kali Undercover theme
The new Undercover theme which turns your Kali machine looks like a default Windows installation.
Then the magic happens, your Kali machine looks completely like a Windows installation which gives you more anonymity and you can switch back to the Kali theme whenever you like.
PowerShell
Another notable feature is the PowerShell repositories, with the new version you will get the ability to run the PowerShell scripts directly on Kali Linux.
BTRFS Snapshot
BTRFS is a much more useful inclusion, if you are running the Kali Linux directly on the computer there is not easy to make a snapshot of it for restoration if something went wrong.
With BTRFS now you will be getting a snapshot capability on a bare metal install while installing the Kali itself a separate btrfs partition and btrfs subvolumes outside of the installation volumes.
