Today, Kali Linux has released its first update of the year, Kali Linux 2025.1a, introducing new tools, desktop environment enhancements, a refreshed theme, and an updated kernel for Raspberry Pi devices.
New Tool in Kali Linux 2025.1a

Raspberry Pi Support
The Kali Linux 2025.1a image for Raspberry Pi now incorporates newer software packages, aligning with the raspi-firmware package used in Raspberry Pi OS.
Additionally, the update upgrades the kernel to version 6.6.74, which serves as the official kernel for Raspberry Pi OS. This advancement enables Kali Linux to fully support the Raspberry Pi 5 series, expanding its capabilities on single-board computing devices.
