The lightweight Debian-based distribution DietPi 10.3 has officially been released. According to the official release notes, DietPi v10.3 was released on April 18, 2026, and this update brings new hardware support, new software, multiple enhancements, and several bug fixes. DietPi itself continues to focus on being a highly optimized operating system for single-board computers and other low-resource systems.
One of the most visible changes in DietPi 10.3 is new support for the Orange Pi 4 LTS. The official release notes say that support and images for the LTS version of this Rockchip RK3399-based board have been added. That is useful news for users who want to run DietPi on more recent or better-supported ARM hardware.
Another notable addition is Prometheus, which has now been added to the DietPi software catalogue as a new software option. Prometheus is a well-known open-source monitoring and alerting toolkit, so this addition is especially interesting for users who want lightweight system monitoring, metrics collection, and service visibility on their SBC or server setup.
DietPi 10.3 also includes a major change for Home Assistant users. The project has migrated its Home Assistant installation and management process from pyenv to uv, which means Python no longer has to be compiled from source during installation. According to the release notes, this makes installs and reinstalls significantly faster and less resource-intensive. The Home Assistant install directory has also been moved from /home/homeassistant to /opt/homeassistant, although DietPi does not force that migration automatically.
There are also practical system improvements in this release. DietPi-Drive_Manager no longer recreates /etc/fstab from scratch, but instead changes only the relevant entries. This is a meaningful improvement for administrators who use custom mount options and do not want automated tools overwriting their manual configuration. A new USB auto-mount feature has also been added, allowing storage devices to be automatically mounted under /media/<uuid> when plugged in, while still respecting existing fstab logic such as noauto and x-systemd.automount.
On the cleanup side, QuiteRSS has been removed from dietpi-software because it has been removed from Debian Trixie due to outdated dependencies and a lack of development for more than five years. The release notes suggest RSS Guard as an alternative.
DietPi 10.3 also fixes a number of hardware and software issues. The official notes mention a fix for an Allwinner H5/H6 regression that caused systems to use only a single CPU core, a fix for Rockchip RK356x PCIe detection issues affecting devices such as M.2 SSDs and 2.5 Gbit Ethernet adapters, and a fix for the Orange Pi Zero 2W Ethernet extension board after a Linux 6.18-related driver issue. There are also fixes for Wi-Fi SSIDs with spaces, locale-related DietPi-Dashboard problems, Home Assistant backup restoration, and service startup issues tied to moved userdata.
Overall, DietPi 10.3 looks like a solid maintenance and feature update rather than a radical redesign. It adds useful new functionality, improves compatibility with more hardware, modernizes some internal installation methods, and addresses several real-world bugs. For users running DietPi on Raspberry Pi, Orange Pi, NanoPi, Odroid, or similar systems, it is a meaningful release worth looking at. If you are already using DietPi, this release is a good reminder of why the project remains popular: it stays lightweight, practical, and focused on efficient deployment for self-hosted services and SBC environments.
