Project Disclaimer & Heritage

BoredOS is the successor to BrewKernel, a project initiated in 2023.

While BrewKernel served as the foundational learning ground for this OS, it has been officially deprecated and archived. It no longer receives updates, bug fixes, or pull request reviews. BoredOS represents a complete architectural reboot, applying years of lessons learned to create a cleaner, more modular, and more capable system.

Important

Please ensure all issues, discussions, and contributions are directed to this repository. Legacy BrewKernel code is preserved for historical purposes only and is not compatible with BoredOS.
