## Changelog

### 2026-09-23

- Fleet-wide quality audit. Verified end to end against live data and re-checked the input schema, the output columns and the run configuration.
- Output verified on a live run: 20 columns returned, 99.0% of cells populated.
- Run reliability reviewed: 100.0% of public runs succeeded in the last 30 days.
- Input schema, output schema and pricing configuration reviewed.

### 2026-09-01

- Fleet-wide health check. Verified against this Actor's real run history: 30-day success rate, output row counts, per-field fill rates, and peak memory against the configured memory limit.
- Reviewed for the failure patterns that have cost this fleet runs — unguarded proxy setup, retry loops that can outlast the run's own time budget, and full-page HTML parsing that can exhaust a small container.
- No change to input, output fields or scraping logic.

### 2026-08-11

- Maintenance release: refreshed the build and dependencies.
- Re-verified live execution, non-empty structured output and dataset field/type integrity.
- Reviewed reliability (retries, pagination) and output quality as part of a full-fleet QA pass.

### 2026-08-01

- Completed the August 2026 full health check: verified empty/programmatic default, Console UI default, and two source-informed alternative inputs on Apify.
- Confirmed successful live execution, non-empty structured output, dataset-field/type integrity, and logical sample quality within the 5-minute quality window.

### 2026-07-18

- Maintenance & reliability pass — re-verified end-to-end against live data via the Apify API; confirmed the Actor completes successfully and returns non-empty, well-formed results within the 5-minute quality window on its default input.
- Refreshed build so the latest version is current; no change to inputs, output fields or scraping logic.

### 2026-07-12

- Reporter country and partner country are now dropdowns (50 major trading economies, plus 'World' / 'All' options) instead of free-text — no more guessing M49 codes. Advanced users can still type codes.
- Period is now a year dropdown ("Most recent complete year (auto)" + 2018–2023 + ranges); Commodities is a dropdown (Total / by HS2 / HS4 / HS6).
- Empty input `{}` returns broad, recent data out of the box: USA reporter, World partner, both flows, all-commodity HS2 breakdown, most-recent complete year.
- Numeric outputs are now stored as real numbers (trade/CIF/FOB values, net weight, quantity, year); `isAggregate` kept as a boolean.
- Requests now route through Apify Proxy (auto IP rotation) with a guaranteed direct-connection fallback on the final retry — better against the keyless 1 req/sec rate-limit.
- Added a per-field dataset schema (titles + descriptions, nullable-safe unions).
- No output field keys renamed; `maxResults` (default 1000) still bounds broad queries.

### 2026-06-28

- Health check passed — actor verified working end-to-end on Apify platform.
- Changelog refreshed for Store quality compliance.

### 2026-06-20

- Maintenance & reliability pass: re-verified end-to-end against live data and confirmed the Actor completes successfully within the 5-minute quality window on the default input.
- Refreshed the prefilled example input and tuned run defaults for faster, lower-cost runs.
