During August 2025, Yunhao focused on improving stability in the cashapp/misk repository by addressing a compatibility issue with gRPC dependencies. He managed the downgrade of gRPC-related libraries from version 1.75.0 to 1.74.0 across multiple modules using Gradle’s version catalog, specifically editing the libs.versions.toml file. This targeted change preserved the existing API surface and minimized deployment risk, ensuring continued CI/CD reliability. Yunhao’s work demonstrated careful dependency management and build configuration skills, providing a cleaner upgrade path for future gRPC updates. The approach maintained consistent versioning across the codebase and reinforced best practices in dependency governance using TOML.
