Changelog

Every deploy, every fix, every new feature. Built in public, shipped iteratively, version-stamped on every page so you always know what's live.

V1.0.28

Phase N · Live Forecast2026-06-22

• Injury availability — NBA forecast cards now show current player injury availability (informational).
• Automated integrity safeguard now active — an automatic check now runs on every release and verifies each published figure before the site goes live, so a stale or mistyped number can't reach the public pages.
• Accuracy-number integrity check — every performance figure shown across POSEIDON is now tied to our published, validated model, with a new internal safeguard that keeps it that way.
• Every published accuracy figure now reads from one live source — across the calibration record, methodology, homepage, and live forecast (and the Spanish site, in its own number format), so the numbers stay consistent everywhere and can't go stale.

V1.0.27

• Multilingual rollout underway — moving to fully translated pages, one language per URL (e.g. /es/), starting with Spanish. Built for search from day one: hreflang, per-language sitemaps, self-referencing canonicals.
• Spanish site now live across the public pages — homepage, methodology, forecast, history, scenarios, calibration, sandbox, community, and terms all have Spanish (/es/) versions, with a compact EN · ES switcher in the nav that takes you to the same page in the other language. (Spanish copy is being reviewed by a native speaker.)
• Footer version accuracy restored — the build-time stamp now reflects each release correctly.
• Consolidates the v1.0.27 rc-line: rc1 (picker foundation) → rc1.1 (site-wide) → rc1.2 (embedded homepage orbit) → rc1.3–rc1.4 (orbit geometry) → rc1.5–rc1.6 (title sizing + balance) → rc1.7 (version metadata fix) → rc2–rc2.9 (i18n generator + sitemap/SEO hygiene) → rc3.0 (/es/methodology) → rc3.1 (EN · ES nav toggle) → rc3.2 (/es/forecast) → rc3.3 (six more Spanish pages: history, scenarios, calibration, sandbox, community, terms).
