Changelog

What is shipping in SignalGrid.

We post here when something changes. Breaking changes are flagged and announced at least 90 days in advance.

  1. feature

    Cross-vertical entity graph in public beta

    Entities resolved in one vertical now carry their identity across the other nine. A film entity from Box-Office Prediction surfaces in Celebrity Equity through its lead, in Music Virality through its soundtrack, and in OTT Demand through its post-theatrical window.

  2. improvement

    Calibration audit shipped on every prediction response

    Every score now ships with a calibration_bucket field showing the historical hit rate of predictions in its decile. Use it to weight predictions by the model's track record at that confidence level.

  3. feature

    Slack alerts for Crisis Radar

    Connect a workspace, pick the entities you track, and receive a single Slack message per breakout above your severity threshold. Includes the recommended posture per archetype inline.

  4. breaking

    v2 prediction response shape

    Renamed score to predicted_value, added ci80 alongside ci95, and moved drivers under an explanations key. The v1 shape continues to work with an Accept-Version header through July 2026.

  5. improvement

    Music Virality short-video coverage tripled

    Sound-usage panel coverage now includes Reels and YouTube Shorts in addition to TikTok. The shortVideoVelocity field is unchanged but its underlying signal is materially broader.

  6. fix

    Box-office territory rollups corrected for split releases

    Films released in different territories on different dates were sometimes double-counted in the international rollup. Fixed and backfilled across the last 18 months of historical predictions.

  7. feature

    Webhooks and signed deliveries

    Subscribe to entity events. Every webhook payload is signed with HMAC-SHA256 so your handler can verify the sender. Retries with exponential backoff up to 24 hours.

  8. improvement

    Faster cold-start for Influencer ROI

    First-time scores for unseen creators now return in under 800 milliseconds at p95, down from 4.2 seconds. Driven by precomputed audience-fingerprint embeddings.

  9. feature

    Athlete Equity launches with NBA, EPL, and NFL coverage

    Forward 12-month sponsorship-equivalent valuation per athlete, including category fit across apparel, beverage, finance, and gaming. NIL benchmarks included for college athletes in covered programs.

  10. fix

    Sentiment scoring corrected for ironic political coverage

    Headlines like 'great job, senator' were occasionally scored as positive. Retrained the head with a satire-aware sample and revalidated against a held-out 2024-cycle set.

  11. feature

    Snowflake share for Brand and Commerce

    Daily refreshes of demand and pricing-pressure tables delivered via Snowflake share. No ETL on your side, no rate limits.

  12. improvement

    Wider confidence intervals for early-window box office

    We were systematically over-confident in opening-weekend predictions made more than 60 days from release. Recalibrated; intervals are wider but the calibration_bucket field is now flat across the prediction horizon.
