v1.5.0 — and the registry gets a version of its own
23 August 2026 · Nabu news
Nabu v1.5.0 bundles the last four phases — the Korean desk, the instrument honesty work, the Latin and Romance wave, and the closing polish — into one release: 988,556 documents, 73.6 million passages, 134 language codes.
The headline of the polish phase is time. The library now reads dating in whatever form each source ships it — a German manuscript catalog’s “1487/88” and its century-half grid, the Patrologia’s author life bands, the Joseon annals’ per-day entry dates, even exact Seleucid-era arithmetic for Babylonian scholarship — and turns all of it into honest machine bounds: 821,916 documents dated, with a new chronological browse spanning 55 centuries. And because dates compose with the language registry’s period bands, the closing pass placed 128,051 documents onto their language’s own timeline — sixty-three thousand classical Latin inscriptions among them — with no human touching a single row.
Search grew honest edges to match: queries no longer leak one script’s transliteration rules into another’s (a Portuguese search stopped reaching Romanian through Old Church Slavonic), and scoped searches now ride inside the index itself, so hunting a phrase in one Korean chronicle among a million documents actually looks at that chronicle.
Beside the library, the language registry it leans on — nabu-lects — cut its own first release: v1.0.0, 110 anchors and 68 historical stages under a semantic-versioning contract on the identifier space itself. The release week settled a question the small languages had been waiting on: where do dialects live? Answer: as typed varieties with their internationally registered names — the six dialects of Occitan and Aranese, the Val d’Aran’s own Gascon, are the first through the door. Hittite finally got its anchor too, with thirty-six thousand tablets behind it.
The library and its registry now version together — and the next waves (the Menota Nordic manuscripts, the Corpus of Middle English) already have their doors open.
