Release Announcement: Nitrux 6.1.0

By Uri Herrera20 May, 2026Changelog

Today is the day! — Nitrux 6.1.0 is available to download

We are pleased to announce the launch of Nitrux 6.1.0. This new version combines the latest software updates, bug fixes, performance improvements, and ready-to-use hardware support.

  • ⚠️ Important: Despite the efforts and improvements in this and previous releases, we’re not claiming to be security or forensic experts or that the distribution is “impenetrable” or “unhackable,” so there is no misunderstanding. Suggestions for continuing to improve this area are welcome at our organization on GitHub (open a new discussion).

For users of the previous version (6.0.0), once the OTA update is available, use the Nitrux Update Tool System.

Unyielding Presentation

The presentation layer functions as a direct extension of the system architecture. We design our interfaces as functional components of specialized systems, never as generic or decorative layers.

True optimization requires eliminating compromises and focusing entirely on the native Nitrux experience. For this release, our conviction was to improve MauiKit and the Maui Apps.

The UI must match the hardware’s capability. By using x86-64-v3 as the baseline across our core libraries and applications, we guarantee our software actively leverages modern CPU instruction sets.

A native interface demands deterministic behavior across the ecosystem. Maui Apps provide consistency through uncompromising component management. We standardized application shells to provide a stable layout and navigation behavior.

Furthermore, we integrate security hardening directly at the application level, enforcing credential isolation, secure local servers, and strict URL validation. The visual architecture executes with the same precision as the core system.

We push Nitrux to the redline, and we engineer its interface to endure.

We thank our friends at Packagecloud for providing Nitrux Latinoamericana with the vital infrastructure needed to build our distribution.

Lightning-fast, secure, automated package management.

🗑️ Removals and Deprecations

We’ve removed the following components from the distribution.

  • XWayland Video Bridge, because KDE has deprecated the project and no longer maintains it.
  • KDE Flatpak KCM, since it wasn’t working correctly for us.
  • Replaced Wofi with Vicinae, which is more feature-rich, extensible, and uses QML for its UI and does not have any issues displaying launchers for Flatpaks.
