Kali Linux released version 2026.3 on 26 October 2026. The headline change concerns people building their own images: its build scripts are being aligned around consistent options and organisation. The announcement also includes KDE Plasma 6.7 and additional tools.

Why do the build scripts matter?

The project adds container-based building with Docker or Podman. For someone maintaining a laboratory image, that offers a way to separate the build environment from their everyday workstation. It does not mean that Docker is required to install or run Kali.

A new ISO does not automatically mean reinstalling

Kali distinguishes an existing installation from the images used to start a new one. Its documentation describes keeping the system updated through its repositories. Before changing a working laboratory, our recommendation is to check the configured repositories and keep a recoverable copy of important data and settings.

Installer, Live or NetInstaller?

The official documentation recommends Installer when you are unsure. Live starts the system without installing it first. NetInstaller retrieves packages during installation and requires a network connection. Everything targets offline scenarios and involves a larger download. Choosing by version number alone can leave you with an image that does not suit your workflow.
