## Changelog

### 2026-09-24

- **Fixed runs that finished successfully with an empty dataset.** A crawl that is blocked and a search that genuinely has no results both produce an empty file; the Actor now fails with an explicit `NO_ROWS` error and writes a `SUMMARY` record instead of reporting success.
- Diagnosis: DBLP has put its search API behind a bot check that answers every proxy group with a challenge page.
- Retry later. The source has restricted automated access and the Actor will report this rather than return an empty file.

### 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.
- 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

- **Runs with empty input** — no field is required anymore. With empty input `{}` the actor browses a broad, popular slice of the DBLP bibliography (default query per mode) instead of erroring, bounded by `maxResults`.
- **Real numbers** — `year` is now stored as a real number (was a string); it is `null` for author/venue rows.
- **Proxy** — uses Apify AUTO proxy with a direct-connection fallback on the final retry (DBLP is a clean public API).
- **Graceful long runs** — added a ~4 min time budget so large paginations stop, push what was collected, and exit successfully.
- **Schemas** — dataset schema gains per-field titles/descriptions (nullable-safe) and renders `year` as a numeric column.
