This changelog records changes that affect YearBull calculations, classifications, data coverage, presentation, or public interpretation. It focuses on what changed for readers and excludes internal operational details.
Version 1.15 — September 22, 2026
Affected areas: public positioning and interpretation across the Methodology Paper, Data Sources, Validation, and YearBull US Market Structure Weekly.
- Clarified the distinctive purpose of YearBull Rank, Bull Score, YB Market Risk, Cycle, and the Market Bull Index: separating the quality, breadth, liquidity support, resilience, and risk of a move from price movement alone.
- Elevated the observed baseline and stability results so readers can see where YearBull already differs from market-cap and momentum rankings.
- Reframed the weekly research and distribution copy around the original market-structure indicator identified by YearBull.
- Kept material evidence boundaries and known failure cases while removing repetitive disclaimers that obscured the analytical value.
- No production formula, coefficient, classification rule, data source, or indexer order changed in this release.
Version 1.14 — September 22, 2026
Affected areas: public methodology disclosure, provenance, validation, downloads, and weekly market-structure research.
- Published the YearBull Methodology Paper with universe rules, qualitative contribution bands, sample coverage, interpretation boundaries, and a clear proprietary-formula boundary.
- Expanded the public data-source document with field ownership, provenance, freshness, and revision controls.
- Published retrospective comparisons with market-cap rank, 30-day momentum, and volatility baselines, plus sensitivity diagnostics and a prospectively registered out-of-sample protocol.
- Added downloadable validation/chart CSV files and a public data dictionary.
- Launched YearBull US Market Structure Weekly with original charts, a stable issue URL, a named author, and concise social/email editions.
- No production metric formula, classification rule, or indexer order changed in this release.
Version 1.13 — September 21, 2026
Affected areas: Research Hub charts and asset tables.
- Corrected category history charts so changes in the number and types of tracked assets are no longer shown as sudden market moves.
- The sharp drop previously visible in the Layer 1 chart around September 13 was a chart distortion, not a collapse in the Layer 1 market. The revised chart now compares each day consistently with the global crypto market.
- Improved Research Hub tables so all columns fit on wide desktop screens, narrower screens keep scrolling inside the table, and phones use a compact layout.
- No YearBull Rank, Bull Score, YB Market Risk, Cycle, or Market Bull Index formula changed in this release.
Version 1.12 — September 20, 2026
Affected area: Market Overview.
- Made the Market Bull Index history interactive, so readers can point to or tap any day and see its MBI and Liquidity values.
- Added the daily percentage of tracked assets that moved up, both on the chart and in the recent-day history.
- Added clearer chart labels and explanations to make it easier to compare the market reading with broad daily participation.
- No Market Bull Index formula or asset metric changed in this release.
Version 1.11 — September 19, 2026
Affected areas: Research Hub tables and the Top Bullish Liquid Assets table.
- Fixed Research Hub tables so all columns remain accessible, made “Not ranked” labels more compact, and restored consistent green/red styling for 24-hour changes.
- Restored coin images, profile links, and signed 24-hour changes in the Top Bullish Liquid Assets table.
- No YearBull metric formula or classification rule changed in this release.
Version 1.10 — September 18, 2026
Affected areas: venue-data freshness, YearBull Rank presentation, YB Market Risk terminology, and return-table readability.
- Improved Markets notices with clearer freshness wording, an approximate next-update date, and an explanation that venue rows and 24-hour volumes are dated snapshots rather than live quotes.
- Improved venue-data freshness for leading and major market-cap assets.
- Replaced ambiguous Rank labels with the clearer “Not ranked” and “Infrastructure” states, including concise explanations. Rank calculations were unchanged.
- Standardized table labels as YB Market Risk and restored green/red presentation for positive and negative 24-hour, 7-day, and 30-day changes.
- Improved coverage for newly added assets that did not yet have venue information and preserved clear states when no venue data is available.
- Reworded project descriptions as neutral public summaries while retaining the independent-verification warning.
Version 1.9 — September 17, 2026
Affected areas: data quality, classification, metric terminology, and interface reliability.
- Corrected exchange concentration percentages and strengthened validation of global market-cap and volume figures.
- Fixed category matching that could place unrelated assets in AI and RWA Research Hubs.
- Fixed missing rows in Top Exchanges and corrected coin-project attribution and promotional exchange wording.
- Linked coin-header metrics to their methodology definitions, restored navigation dropdowns, corrected short-page footer spacing, and improved responsive coin-page layouts.
- Standardized the public relative-volatility label as YB Market Risk and clarified that it is not an investment-safety rating.
Version 1.8 — September 13, 2026
Affected metrics and areas: YearBull Rank, Bull Score, YB Market Risk, Cycle, Market Bull Index coverage, retrospective research examples, and public data portability.
- Expanded the daily analytical universe and added validation that reduces missing published assets in completed daily results.
- Established dated retrospective examples with asset price and YearBull Rank as the primary historical comparison. A lower Rank number represents stronger relative positioning; Bull Score is shown as additional context rather than a prediction.
- Added asset images, historical charts, coverage and observation counts, clearer limitations, and copyable coin widgets based on the latest completed daily snapshot. No YearBull metric formula changed.
Version 1.2 — September 9, 2026
Affected metrics: Market Bull Index, YearBull Rank universe, YB Market Risk, and Cycle.
- Corrected a calculation-order error so Market Bull Index uses the completed YearBull Rank universe and final asset classifications.
- Replaced the affected Market Bull Index observation. The corrected September 9 value was 78 with approximately 99.9% 30-day coverage.
- Preserved separate stable, infrastructure, and excluded-asset states instead of presenting them as ordinary analytical ranks.
Version 1.1 — Earlier production baseline
Affected metrics: Bull Score, YB Market Risk, Cycle, and YearBull Rank.
- Established one consistent completed daily dataset for price, market capitalization, volume, and YearBull metrics.
- Standardized the distinct roles of Bull Score, YB Market Risk, Cycle, and YearBull Rank across public pages.
