During January 2026, Tianyu contributed to the pacstall/pacstall-programs repository by updating the grub-btrfs package, advancing its version from 4.13 to 4.14. This work involved modifying package metadata, including the description and source URL, to align with upstream changes and ensure users received the latest release. Tianyu utilized shell scripting and applied skills in Linux system administration and package management to implement these updates. While the scope was focused on a single feature, the changes improved package reliability and reduced upgrade friction for users. No bugs were tracked or fixed during this period, reflecting a targeted and maintenance-oriented contribution.
