 ## Version history
 
-- **2026-10** — Full and Lite configurations; three tracks (update, generation, refinement); task set of the TestEvo-Bench paper (Full 3,020 / Lite 584 tasks). Rows are grouped by (repository, revision pair, test file); the `coevolution_rule`, `pair_span` and `java_version_verified` fields are new; the focal-method and retrieval fields of the first release (`focal_*`, `old_production_code`, `new_production_code`, `deps_changes`, `all_deps_old`) are dropped because the agent benchmark does not use them.
+- **2026-10** — Full and Lite configurations; three tracks (update, generation, refinement); task set of the TestEvo-Bench paper (Full 3,020 / Lite 584 tasks). Rows are grouped by (repository, revision pair, test file); the `coevolution_rule` field is new; `java_version` now holds the JDK verified to build the task's own revisions rather than the project's declared version; `version` and `git_diff_url` are dropped (derivable from `project_name`, `git_clone_url`, `rev1`, `rev2`); the focal-method and retrieval fields of the first release (`focal_*`, `old_production_code`, `new_production_code`, `deps_changes`, `all_deps_old`) are dropped because the agent benchmark does not use them.
 - **2026-05** — Initial release: update (509 tasks) and generation (746 tasks) tracks only, `data/train.jsonl`.
