Editions¶
| Version | Date | Change | What changed |
|---|---|---|---|
| v5 | 2026-09-28 | Added the plain-language explanation ladder: age-graded explanations of the idea, from an explain-like-I'm-five version up to a specialist one. | structure — eli ladder (added) |
| v4 | 2026-09-19 | The "Also from" domains were brought onto the canonical roster. Across this pass 148 entries spanning 95 off-roster values fell to 2 over 78 prime abstractions: 80 were renamed to the domain they already meant (biology to Biology & Ecology, forensics to Criminology & Forensic Studies), three of those renames turned out to repeat the prime's own origin domain and were removed rather than kept as an alternate that says nothing, 61 named a specialty rather than a domain — machine learning, epidemiology, network science — and moved to the entry's subdomain where narrow labels belong, and 5 were too generic to tell a reader anything and were dropped. One value whose reading was genuinely unclear was left untouched rather than guessed at. | structure — origin (fields changed) |
| v3 | 2026-09-07 | DS reference campaign batch 5 (50 entries cited, 303 slots, 283 filled and 20 left as reader-facing citation-pending gaps); ~55 prose errors corrected against the sources that establish them and independently reviewed, among them a fabricated place name standing at four sites, an inverted river-avulsion direction, and a pivot chord misidentified in six places; six citations repaired that had resolved cleanly to a review of the book rather than the book; internal editorial placeholders removed from the References section of 36 entries, where an HTML comment had been rendering to readers as literal text; v1 counterparts synced where they still carried an error corrected in v2. | prose — detailed body (prose edited) |
| v2 | 2026-08-30 | internal-notes separation: a wholly internal Notes section relabelled Internal notes | prose — concise body (prose edited), detailed body (prose edited) |
| v1 | 2026-08-24 | First published edition. | first published edition |
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.
