## [Unreleased]

## [0.1.0] - 2026-06-01

### Added

- Initial release: Elixir port of the Ruby `yahoo_finance_client` gem.
- `YahooFinanceEx.get_quote/1` — fetch a single stock quote via Yahoo's
  `/v7/finance/quote` endpoint.
- `YahooFinanceEx.Session` GenServer — handles Yahoo's cookie + CSRF crumb
  auth dance with two fallback strategies (query1, query2). 60-second
  session TTL with on-demand refresh.
- `YahooFinanceEx.Quote` struct — typed result with derived fields
  (`dividend_yield`, `payout_ratio`) computed locally.
- Test stubbing via `Req.Test` so consumers can mock Yahoo responses
  without hitting the network.
