History

BoredOS is the successor to BrewKernel, a project started in 2023. BrewKernel served as the foundational learning ground but has since been officially deprecated and archived — it no longer receives updates, bug fixes, or pull request reviews.

BoredOS is a complete architectural reboot, applying years of lessons learned to build a cleaner, more modular, and more capable system.

Important

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