DietPi, a lightweight and performance-oriented Debian-based Linux distribution designed for SBCs like Raspberry Pi and server systems (with optional desktop environments), has rolled out version 10.3—the third maintenance update in the 10.x series.
This release introduces support for the Orange Pi 4 LTS, along with new images tailored for the Rockchip RK3399 platform. On the software side, Prometheus an open-source monitoring and alerting toolkit has been added to the available software catalog.
Meanwhile, QuiteRSS has been removed after Debian discontinued it in the Trixie release, citing its dependency on outdated libraries and lack of active development for more than five years.
DietPi’s built-in tools have also seen several improvements. DietPi-AutoStart now includes an Amiberry-Lite autostart option, which launches early in the boot process via amiberry-lite.service, similar to the existing fast boot feature for Amiberry.
The drive manager has been refined to update only the relevant entries in /etc/fstab instead of regenerating the entire file. It now also supports automatic USB mounting. When enabled, a udev rule mounts USB storage devices under /media/ upon connection and safely unmounts them when removed. Devices already defined in /etc/fstab continue to follow their configured options, such as x-systemd.automount or noauto.
DietPi Display has expanded support to include Odroid C1 and XU4 systems using /boot/boot.ini.
For Home Assistant installations, DietPi now uses uv instead of pyenv for Python environment management. This change eliminates the need to compile Python from source and allows existing environments to be retained and updated when versions match, avoiding unnecessary reinstallation of modules.
The update also delivers several hardware-specific fixes. For Allwinner H5 and H6 systems, it resolves a U-Boot issue that restricted systems to a single CPU core by applying a corrected build during the update process.
On Rockchip RK356x devices, it fixes intermittent detection problems with PCIe hardware such as M.2 SSDs and 2.5 GbE adapters on NanoPi R5S and R5C boards. The Orange Pi Zero 2W also receives a fix for its extension board Ethernet adapter, which previously failed after upgrading to Linux 6.18 due to a missing driver.
Additional bug fixes include improvements to DietPi-AutoStart, ensuring that switching away from the Amiberry fast boot option correctly disables the related service. DietPi-Config also addresses a regression introduced in version 10.1 that caused WiFi SSIDs containing spaces to be displayed and applied incorrectly.
