Changelog

0.1.9 — 2026-10-20

Fixed

• clj-yfinance.dataset/dividends-splits->dataset (and the Kindly variant) threw on real Yahoo data: event maps are keyed by keywordized epoch strings (:1699574400), which were used as the timestamp. Timestamps now come from each event's :date, and rows are sorted by date. Split :numerator/:denominator columns are now float64, matching Yahoo's values.
• Experimental quoteSummary functions (fetch-fundamentals, fetch-financials, …) retried a 401 with the stale crumb still in the URL, so the retry could not succeed. auth/authenticated-request now also accepts the URL as a function of the crumb and rebuilds it after the refresh; options use the same path.
• clj-yfinance.kindly functions returned [nil] instead of nil when there was no data.
• auth/session-info :age-minutes is a double instead of a ratio; the crumb value is no longer printed.
• clj-yfinance.duckdb/run! no longer triggers a "replacing clojure.core/run!" warning on load.
• Demo notebook (examples/finance_demo.clj) runs end to end again: chart titles go through plotly/base (current tableplot's plot takes one argument), and the normalised-performance chart and ticker-info table no longer throw.

0.1.8 — 2026-08-22

Breaking

• :auto-adjust now defaults to true in fetch-historical / fetch-historical* (and everything built on them: datasets, Parquet, DuckDB). :open/:high/ :low/:close are back-adjusted for dividends and splits, matching python-yfinance. Pass :auto-adjust false for raw OHLC.
• :adjusted option removed from fetch-historical / fetch-historical* (and the pass-through in parquet / duckdb). Yahoo's adjclose series is always requested and :adj-close is always present when Yahoo provides it. Rows therefore have a fixed shape; under :auto-adjust true, :adj-close equals :close.
• License changed from EPL-2.0 to Apache-2.0.
• project.clj removed; deps.edn + build.clj are the only build files.

Changed

• OHLC row building extracted into the pure clj-yfinance.parse/chart->rows (with unit tests).
• Provided-scope POM dependencies are derived from the deps.edn aliases.
• tech.ml.dataset alias bumped to 8.024.
• CI now runs the dataset tests and fails the build on test failures (previously every step exited 0 regardless of results).
