Yuyongqiang.yyq worked on the secretflow/spu repository, focusing on maintaining build stability through careful dependency management. During the month, he updated the Bazel build configuration to ensure compatibility with the latest version of the Psi library, moving from 0.6.0.dev250922 to 0.6.0.dev260105. This change allowed the project to access new features and fixes while minimizing integration risks. His work centered on build configuration and dependency management, leveraging Bazel as the primary build tool. The scope was targeted, addressing a specific compatibility need rather than broad feature development, reflecting a focused approach to maintaining project reliability and up-to-date dependencies.
