@@ -14,6 +14,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
- Better more robust error handling in ROGCC
- Try to better handle pre-2021 laptops with lightbar
- Add more logging to try and trace the charge_control_end_threshold issue
- Make `kbd_brightness` optional to work around issues on some laptops that seem to lack it. Likely this will all need a refactor *again* if work proceeds in kernel for better RGB support.

A gui is now in the repo - ROG Control Center. At this time it is still a WIP, but it has almost all features in place already.
**NOTE**: Xorg is not supported.
# BUILDING
Rust and cargo are required, they can be installed from [rustup.rs](https://rustup.rs/) or from the distro repos if newer than 1.75.
