CachyOS April 2026 Release Brings Major Security and Usability Upgrades The April 2026 release of CachyOS introduces significant improvements focused on security, usability, and system responsiveness, marking another milestone in the evolution of this Arch Linux-based distribution. Built on the Linux 6.18 LTS kernel and featuring KDE Plasma 6.6.4 as the default desktop environment, the update centers on three key advancements: a new graphical package manager, system-wide DNS-over-HTTPS support, and fingerprint-based authentication for sudo operations. At the forefront of these changes is the adoption of Shelly as the default GUI package manager, replacing Octopi. Shelly, described as a “modern reimagination of the Arch Linux package manager,” provides a unified interface for installing software from multiple sources including the Arch User Repository (AUR), Flathub, Flatpak, AppImage, and local source files. This shift aims to simplify package management for both new and experienced users while maintaining access to Arch’s extensive software ecosystem. Security enhancements are equally prominent. The CachyOS Welcome application now includes built-in support for DNS-over-HTTPS (DoH), allowing users to encrypt DNS queries and improve online privacy. The feature enables users to test connection speeds, automatically select the fastest resolver, or configure custom DoH servers directly from the installer or post-installation setup. Complementing this, the chwd hardware detection tool has been updated to automatically configure fingerprint readers for sudo authentication. When a compatible fingerprint sensor is detected, users can now authorize privileged operations using biometric verification instead of entering a password, streamlining administrative tasks while strengthening system security. Performance tuning also received attention in this release. In response to user feedback and benchmarking, the default I/O scheduler for NVMe storage devices was changed from “none” to “kyber” within the CachyOS Settings utility. This adjustment aims to improve responsiveness under mixed workloads by balancing latency and throughput more effectively than the previous default. Additional refinements include updated Plymouth themes for AMD GPUs to resolve rendering issues on laptops with secondary displays, improved power management for specific Intel CPUs, and enhanced handling of laptop-specific edge cases during hardware detection. The installer itself has undergone several updates. It now creates a clean system snapshot immediately after installation, which is retained permanently as a reliable restore point. GRUB’s os-prober is enabled by default to detect other operating systems during dual-boot setup. Users can also opt to install MangoWM with the DMS shell directly from the installer interface. Other changes include the removal of the UKUI desktop option, cleanup and modernization of the GNOME package selection, and updated NVIDIA driver profiles that eliminate forced Xorg sessions for the 470xx series. These updates collectively reinforce CachyOS’s focus on delivering a polished, secure, and high-performance Arch Linux experience. By integrating modern tools like Shelly, DoH, and biometric authentication while optimizing low-level system behavior, the April 2026 release addresses both everyday usability and advanced user needs without compromising the flexibility that defines the Arch ecosystem.
