## Changelog

All dates are UTC. Build numbers are the Apify build that shipped the change.

### 2026-10-18

- Published on the Apify Store.
- Store title, description, README and input form rewritten. The prefill now returns the 10 most traded Fed decision markets on each venue (20 rows) in about 10 seconds.

### 2026-10-16 (0.1.5)

- The memory behind `onlyNew` and `onlyChanged` opens safely; if your account's storage refuses it, the run continues and says so instead of failing.

### 2026-10-15 (0.1.1-0.1.4)

- First release: Kalshi and Polymarket markets in one table by search term, category or link, with implied probability, volume, liquidity, open interest, bid and ask, close time and result.
- The same question matched across both venues (`matchKey`, `matchedWith`, `probabilityGap`), optional hourly or daily price history and top-5 order book, and `onlyNew` / `onlyChanged` for schedules.
- Maintenance: shared request code updated; output unchanged.
