Editions are cut at publish time from a content hash of the entity's canonical source, so a version changes only when the content actually changed. Full canonical content for every edition, and the exact per-part diffs between them, are in the downloadable editions archive (editions_archive.jsonl); the current-state index is versions.jsonl.
