# Version History

> Every dataset and evaluator edit, saved as a browsable version

Every edit to a dataset or Evaluator config is saved as a new version - diffed against what changed (`"Updated acceptance criteria, questions"`), shown newest-first with a `v{N}` badge, browsable from a **Version history** panel in the edit dialog. Click **Apply this version** to pull an older version's fields back into the form (you still have to hit Save to actually restore it - this doesn't overwrite anything on its own), or **Delete** to remove a specific version from the log. The very first save is always recorded too (`"Created"`), so a freshly-made dataset never shows an empty history. A no-op save (open the dialog, change nothing, hit Save) doesn't create a new version - only genuine field changes do.
