Worked on backend development and version management for the libnyanpasu/clash-nyanpasu repository, focusing on improving reliability in version handling. Addressed a bug in the clash-rs core version format by implementing logic in Rust to ensure the core version string consistently includes a 'v' prefix when missing, while preserving the behavior for other core types to avoid regressions. This targeted fix enhanced downstream parsing and reduced issues related to release compatibility across components. The approach prioritized backward compatibility and minimized risk, resulting in more robust version normalization and smoother integration for systems relying on accurate version information within the codebase.
