25.08

Section titled “25.08”

Features:

  • Kernel: The installer now additionally installs linux-cachyos-lts as a secondary/backup kernel after installation. We still recommend using the Stable kernel.
  • ISO: Switched the live ISO’s kernel from Stable to LTS due to ongoing issues with the Stable kernel, improving boot reliability.
  • Desktop: Added Niri as a desktop option, including a few preconfigured dotfiles.
  • NVIDIA: Enabled S0ix sleep on supported hardware for modern low-power standby.
  • GRUB: Bootable snapshots are now automatically enabled and set up when the root filesystem uses Btrfs.
  • Tweaks: Integrated Cachy-Update into the Welcome app’s Tweaks page. Cachy-Update adds a timer and a system tray indicator to notify users about updates and lets them update with a click.

    • Added per-game shader cache, enabled by default, can be disabled with PROTON_LOCAL_SHADER_CACHE=0. Shaders will be cached under <steamlibrary>/shadercache/<appid> for each game, similarly to when shader pre-caching is enabled. You will get stuttering as the shader cache for each game is rebuilt but the cached shaders won’t be evicted due to limited cache size.
    • Added dxvk-sarek as an optional DXVK replacement for older GPUs that don’t properly support Vulkan 1.3. It is using the async branch, so it SHOULD NOT to be used with games using anti-cheat or multiplayer games in general. You have been warned. Use PROTON_DXVK_SAREK=1 to enable.
    • Added PROTON_FSR3_UPGRADE to upgrade FSR 3.1 DLLs to newer versions.

Fixes:

  • Limine:
    • Fixed limine bios-install /dev/sdaX error when selecting the /boot mount point as the boot location on MBR systems.
    • Fixed uninitialized value of the bootLoader path, which caused installation failures on MBR systems when the bootloader location wasn’t explicitly selected.

    • Fixed out-of-the-box dual-boot with Windows for BIOS installations.
    • Fixed Btrfs snapshots failing to boot when using GNOME (GDM).

CachyOS was founded a year ago. After almost one year of development, we are really proud to announce our first Stable Release of GUI Installer. We spent a lot of time investigating repo management, kernel development, infrastructure, theming, … and finally put them all into the CachyOS GUI Installer. All the features we worked on and implemented into the Installer are just trying to offer users a completely customizable experience.

The most exciting changes are that we use now for the online install pacstrap which provide then a complete clear installed environment and we do support a complete native support for the zfs filesystem

Since Discord restrict the length of the messages the full announcement can be found here:
