 ## 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` 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.

A benchmark for test refinement in evolving Java codebases: the developer's old test already passes on the new code, and the developer edits it so that it covers more lines of the production methods it executes.

Every task is a (repository, revision pair, test file) group validated by executing the developer's tests on both revisions.",
