Changelog

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).
