January 2026 (2026-01) focused on strengthening artifact storage reliability in google/adk-go by addressing a filename validity edge case. Implemented a fix to prevent path separators in artifact filenames, added validation logic, and introduced tests to prevent regressions. This reduces risk of broken object name layouts and file handling failures in downstream processes.
