Changelog

0.1.10 — 2026-10-31

Added

• clj-yfinance.experimental.timeseries: full income statement, balance sheet and cash flow statement from Yahoo's fundamentals-timeseries endpoint (no cookie or crumb). fetch-statements / fetch-statements* return one row per statement, field, frequency (annual, quarterly, trailing) and period end, with the reporting currency; fetch-timeseries / fetch-timeseries* give raw access by Yahoo type string, sent in chunks of at most 100 types per request with the chart endpoint's retry and host failover. The field catalog (statement-fields, 375 fields) comes from python-yfinance's fundamentals_keys; field->keyword maps Yahoo names to kebab-case keywords.
• clj-yfinance.experimental.earnings: fetch-earnings-history / fetch-earnings-history* (last four quarters from the quoteSummary earnings module: period end, report date and instant, EPS actual vs. estimate, surprise) and fetch-earnings-dates / fetch-earnings-dates* (announcement history from Yahoo's visualization API, paged at 250 rows per request).
• fetch-historical* returns the chart metadata (symbol, currency, exchange, instrument type, first trade date, time zone, GMT offset, names) as :meta.
• fetch-historical* option :events (default false): also return the window's dividends and splits as :events, in the shape fetch-dividends-splits returns, from the same request.
• experimental.auth/authenticated-request accepts :method (:get or :post), :body and :content-type; the 401 retry repeats the same request.

Changed

• clj-yfinance.http/get-with-failover* is the generic GET with retry, backoff and host failover that the chart endpoint uses; chart behaviour is unchanged.
• fetch-financials docs point to experimental.timeseries for full statements.

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, not always equal to the event date), 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).
