The short answer
Version a benchmark whenever questions, references, source evidence, or scoring rules change in a way that can alter the result. Preserve old records and publish a change reason. A version number is useful only when reviewers can identify which components changed and whether historical comparisons still measure the same task.
What to take away
- Version data, references, and scoring separately.
- Explain why a change can affect results.
- Use bridge analysis instead of splicing incompatible trends.

Separate the versions that affect a score
Hugging Face Datasets documents loading specific revisions by tag, branch, or commit. A pinned dataset revision is one part of benchmark identity; application prompts, source snapshots, reference labels, and evaluator code can change independently.
Give those components explicit identifiers and combine them in a run manifest. A case may keep its stable conceptual ID while acquiring a new revision after a label correction. Preserve the previous revision so an old score can still be explained rather than retroactively appearing to have used the corrected answer.

Classify changes by their consequences
Distinguish editorial wording fixes from changed task meaning, corrected references, added coverage, and new scoring policy. Describe the effect directly instead of relying only on major or minor numbering. Even a short negation added to a question can reverse its expected answer.
When a source policy changes, decide whether the benchmark tests the old historical snapshot or the new product behavior. Both can be legitimate, but they answer different questions. Updating the source without updating the reference and version record creates a mixed benchmark that no longer has a coherent interpretation.
Run a bridge comparison when meaning changes
Use an illustrative bridge table that scores the same retained outputs under the old and new rubric. Identify which cases change judgment and why. This separates a scoring-policy change from an application improvement. Do not describe a higher score caused only by a more permissive rubric as a better model.
For a changed dataset, report performance on the common case intersection as well as the full new suite where useful. Keep that intersection’s limits visible: it can support continuity while omitting the very new workflows that motivated the expansion.
| Case or record | Expected check | Decision |
|---|---|---|
| Reference correction | Same output scored against corrected evidence | Rescore and label the change |
| New task family | Coverage population expands | Start a new full-suite baseline |
| Historical policy snapshot | Old task remains intentionally frozen | Retain with explicit historical scope |
Retire versions without erasing evidence
Mark obsolete benchmark versions as historical and state why they should no longer gate current releases. Keep prior manifests and results under the retention policy. Prevent a dashboard from merging incompatible versions into a smooth trend without a visible boundary.
Approve a benchmark release with a changelog, migration notes, a reference review, and a decision about comparability. If the change introduces new case families, label the first result as a baseline for that version. Versioning should help users understand evidence, not imply that an older benchmark became invalid merely because a newer one exists.
Limits of the evidence
This versioning method is a proposed publication and comparison policy. It cannot establish that a corrected label is right or that a retained intersection represents new workloads. The cited loading interface supports revision selection, not automatic methodological comparability.
Common questions
Can I keep the same case ID after a correction?
Yes, with a distinct revision and preserved history. The run must identify which revision it used.
Should every wording edit break comparability?
Assess whether it can change interpretation, difficulty, or scoring. Record that judgment rather than assuming all small edits are harmless.
