During March 2026, Bikku contributed to the nix-community/home-manager repository by addressing a compatibility issue affecting Proton and Lutris integration. Bikku focused on NixOS configuration and package management, specifically correcting the linkage of Proton packages so they would be properly discovered by Lutris version 0.5.20 and above. By aligning Proton package links with the Wine directory, Bikku resolved visibility problems that previously hindered user experience. The work involved targeted changes in Nix, along with updates to project documentation and release notes to support future troubleshooting. This contribution demonstrated careful attention to software compatibility and maintainability within the Nix ecosystem.
