Worked on the zed-industries/extensions repository to deliver a targeted dependency upgrade focused on theme development and version control. Upgraded the Sublime Mariana Theme to version 1.1.4, ensuring UI stability and maintainability by updating submodule references and aligning versioning with upstream changes. Emphasized traceability by providing detailed release notes and commit history, which supports future maintainability and minimizes the risk of UI regressions. Utilized TOML for configuration management and maintained a clean repository structure by centralizing theme versioning. No major bugs were reported or fixed during this period, reflecting a stable and well-managed update process for the project.
