The CachyOS team has released the June 2026 ISO, delivering another feature-packed update for its Arch Linux-based distribution. Known for its aggressive performance optimizations and gaming-focused approach, CachyOS continues refining both the user experience and the underlying system with improvements ranging from compiler tuning to installer enhancements and new desktop options.

As the project's fourth major ISO refresh of the year, the June release emphasizes speed, usability, and modern hardware support while remaining fully compatible with Arch Linux's rolling-release ecosystem.

A New Hyprland Noctalia Desktop Experience

One of the headline additions is a new Hyprland Noctalia desktop option available directly from the installer.

Noctalia provides a polished, preconfigured Hyprland environment with a modern appearance, allowing users to enjoy a highly customizable Wayland compositor without spending hours configuring dotfiles after installation. The installer even includes a preview so users can see the desktop before selecting it.

For users interested in lightweight, keyboard-driven workflows, this new option makes Hyprland much more approachable.

Performance Optimizations Continue

Performance remains the defining characteristic of CachyOS, and the June 2026 release introduces several additional optimizations.

Notable improvements include:

  • Python packages now built using extended Profile-Guided Optimization (PGO)
  • A new GCC branch prediction tuning patch designed to improve performance on modern Intel and AMD processors
  • A fix for an OpenBLAS regression affecting high-core-count CPUs
  • Additional package-level optimizations throughout the distribution

These updates continue CachyOS's philosophy of extracting as much performance as possible from modern hardware.

Improved Package Management and Security

The June release also includes several important changes to package management.

One notable enhancement is network isolation for Pacman scriptlets and hooks, preventing installation scripts from accessing the network by default. This improves security during package installation and reduces the risk of unexpected behavior.

Additionally:

  • proton-cachyos has been renamed to proton-cachyos-native
  • The installer no longer includes the paru AUR helper
  • Users are now encouraged to use Shelly, available with both graphical and command-line interfaces
Installer Improvements

The installation experience has received considerable attention in this release.

South Korea To Spend $1 Trillion On More Memory Chip Production, Humanoid Robots

1 week 2 days ago
An anonymous reader quotes a report from Ars Technica: South Korea's government and top tech companies are committing $1 trillion to several flagship megaprojects that could bolster global memory chip supply, build new AI data centers and spur commercial deployment of humanoid robots by 2028. [...] "We must secure the core elements of AI faster than any other country," said South Korean President Lee Jae Myung in a televised speech on June 29, as reported by BBC News and other media outlets. "Semiconductors, physical AI, and AI data centers are the triple axis for a great leap forward." [...] The most costly of the megaprojects involves Samsung and SK Hynix committing $585 billion to building new chip fabrication plants in the southwest provinces of South Korea, along with boosting semiconductor fab construction in the Seoul capital region, according to Reuters. The government's goal is to double South Korea's production of dynamic random-access memory (DRAM) within five years. [...] The second flagship megaproject involves a $357 billion investment by the South Korean tech companies SK Group, GS Group, and Naver into building large-scale AI data centers in more outlying provinces, including South Chungcheong Province in the west, Gangwon Province in the east, and the North and South Jeolla Provinces in the southwest corner of South Korea. The third flagship megaproject revolves around the South Korean government assigning a "national strategic industry" designation to physical AI -- the AI systems that enable robots and self-driving vehicles to interact more autonomously with the real world. The government aims to develop a Korean "general-purpose foundation model" based on a world model to support robots within three years, according to The Chosun Daily. Hyundai Motor Company has also committed $5.8 billion to build a robot manufacturing facility and AI data center in the Saemangeum region of North Jeolla Province in the southwest, The Chosun Daily reported. The South Korean automaker has already been helping Boston Dynamics -- the US robotics company it acquired in 2021 -- use the South Korean supply chain in scaling up manufacturing to produce 30,000 Atlas humanoid robots each year by 2028. Similarly, the South Korean government announced it would aim to commercialize humanoid robots in 10 major industries by 2028, along with training 10,000 human workers as "AI robotics specialists" over the next five years, Reuters reported.
