CachyOS May 2025 Release Changelog

Features:*

- *ISO*: Added automatic detection during ISO boot to identify the system's NVIDIA GPU and load the appropriate module (e.g., nvidia-open, nvidia), providing better support for 10xx series and older.

- *Plymouth*: Added a new Plymouth animation.
- Thanks to Eren ([https://github.com/erenyldz89](https://github.com/erenyldz89)) for working on this!
- *Browser*: Cachy-Browser has been deprecated. We now provide Firefox as the default preinstalled browser. A guide to migrate profiles to Firefox (and its forks) can be found here: [https://wiki.cachyos.org/support/faq/#migrating-your-profile-from-cachy-browser-to-firefox](https://wiki.cachyos.org/support/faq/#migrating-your-profile-from-cachy-browser-to-firefox)
- *netinstall*: Added kcalc, filelight, plymouth-kcm, and kio-admin to the KDE installation.
- *mkinitcpio*: Disabled fallback initramfs by default. This will save a significant amount of space.
- *Mirrors*: Added a new 10 Gbps mirror in Bangladesh. Thanks to Limda for hosting this!
- *Proton*:
- Rebased almost all patches from *Proton CachyOS 9.0*.
- Enabled the Wayland driver for Steam Linux Runtime builds. Enable with `PROTON_ENABLE_WAYLAND=1`. Thanks to [GloriousEggroll](https://github.com/GloriousEggroll) for making it happen.
- Added many Wayland-related patches from upstream Wine that were released after Wine 10.0.
- Fixed various issues with the Wayland driver and Vulkan games. Thanks to [Etaash-mathamsetty](https://github.com/Etaash-mathamsetty) for all the hard work.
- Added a stub implementation for `amdxc64.dll` to enable FSR4. Use `FSR4_UPGRADE=1` to upgrade FSR3.1 games to FSR4. Thanks again to [Etaash-mathamsetty](https://github.com/Etaash-mathamsetty). Instructions: [https://github.com/Etaash-mathamsetty/wine-builds/releases/tag/fsr4](https://github.com/Etaash-mathamsetty/wine-builds/releases/tag/fsr4)
- Added DualSense-related patches for more complete audio device detection functionality for wired sound-based haptics. Some games that relied on that specific behaviour should now have that functionality. Thanks to [ClearlyClaire](https://github.com/ClearlyClaire) for the original patches and [Exotic0015](https://github.com/Exotic0015) for looking into it since *Proton CachyOS 9.0*. Upstream: [https://gitlab.winehq.org/wine/wine/-/merge_requests/7238](https://gitlab.winehq.org/wine/wine/-/merge_requests/7238)
- Removed the Dragon Age Inquisition patch as it was not working. Please use *Proton CachyOS 9.0* for now with that game.
- *GRUB*: Added a new GRUB theme. Thanks to [diegons490](https://github.com/diegons490/cachyos-grub-theme).

*Fixes:*
- *Mirrors*: Fixed an issue where users from Russia could no longer install. This was mitigated by not using CDN77, which Russia had started to block.
- *kde-settings*: Disabled the Discover icon in the taskbar.
- *ddcutil*: Pushed the ddcutil 2.2.1 pre-release to fix an issue where AMD GPUs were freezing when watching YouTube videos.

*Changelog for Handheld Edition:*
- *os-branch*: Game Mode now correctly shows that CachyOS Linux is being used.
- *audio*: Updated convolver profiles.
- *steamos-manager*: This is used for GPU clock and TDP management, BIOS/dock updates, storage device maintenance, external storage formatting, and battery charge limit for the Steam Deck.
- *steamos-powerbuttond*: This component replaces the standard powerbuttond for a better sleep experience.
- *jupiter-hw-support*: Updated to 20250501.
