In May 2025, rclone/rclone delivered a targeted bug fix to the S3 ListObjectsV2 response, ensuring directory entries consistently include a trailing slash. The change appends '/' to object paths when prefixes are added to responses, aligning behavior with how clients distinguish files from directories. The fix is tracked under commit a3f3fc61ee0ffa0c983b20433c7522cd1e00ac67. Business value: improved reliability and interoperability of S3 listings with downstream tools and services, reducing client-side edge cases and potential support tickets. This enhances user trust in rclone's S3 compatibility and minimizes confusion when listing directories. Technologies/skills demonstrated: Go, S3 API semantics, careful response construction, code review and validation, version control hygiene (commit and message quality).
