## Changelog

### 2026-10-15

- Every request now has a hard time limit, so a proxy connection that stalls can no longer hold up the run or push it past its timeout.
- A run that reaches its maximum cost per run now stops cleanly with its results saved and a status message, instead of ending as aborted.
- A proxy group your account cannot use no longer stops the run at start-up; it falls back to the default Apify Proxy.
- Runs with a short timeout (API and AI-agent calls) now finish inside it with what they collected, instead of being cut off.
- Memory is managed within the run's own limit, which removes a rare out-of-memory crash on large pages.
- The default used when the field is left out for `maxResults` is now 10,000 (was 200).

### 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: 15 columns returned, 72.4% 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.
- Noted that 3 column(s) came back empty in this sample (`cpc_class`, `num_claims`, `pdf_url`); these are under review.

### 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.
- Recovered the Actor's missing README from the maintained canonical documentation copy after the live Apify source was found to contain only a broken ../README.md pointer; all 15 documented output fields match the typed dataset contract and retained live samples.

### 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

- **Empty input now returns data.** No field is required — running with `{}` returns the most recent patents (sorted newest first), bounded by `maxResults`. The old "provide at least one filter" error was removed.
- **Numbers are real numbers.** `num_claims` is now emitted as a numeric value instead of a string (null when the source omits it).
- **Friendlier input.** `countryCode` is now a dropdown of patent offices (US, EP, WO, JP, CN, … + "All offices") with human labels. New `sort` dropdown (Relevance / Newest first / Oldest first); defaults to newest.
- **Bounded & graceful runs.** Added a ~4-minute time budget to pagination (pushes what it collected, then exits success). `maxResults` accepts `0` for "everything" (source caps ~10,000/query). Missing input no longer aborts the run; proxy setup failures fall back to a direct connection.
- **Proxy.** Uses Apify Proxy (AUTO, `useApifyProxy: true`) with per-page session rotation. No forced `DATACENTER` group.
- **Schemas.** `output_schema.json` now exposes a `results` dataset link. Dataset schema gained a `fields` JSON-schema (title + description per field); `num_claims` column uses `format: number`. Both schemas linked in `actor.json`.
