## Changelog

### 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

- **No mandatory filters:** the Actor now runs with an empty input `{}` — it no longer exits early when no query/PMIDs are given.
- **Zero-input default:** empty input now browses the most recent biomedical literature (`medicine[MeSH] OR biology[MeSH]`, sorted by date) bounded by `maxResults`.
- **Dropdowns:** added an **Article Type** select (Clinical Trial, Review, Meta-Analysis, RCT, Systematic Review, …) that appends a PubMed Publication Type filter, and a **Sort Order** select (relevance, most recent, publication date, author, journal).
- **Real numbers + new fields:** added `year` (integer) and `authorCount` (integer) to every record.
- **Proxy:** default proxy is AUTO (`useApifyProxy: true`); added a direct-connection fallback on the final retry for the public NCBI E-utilities API.
- **Resilience:** added a ~4-minute time budget for long efetch paginations (pushes what was collected and exits successfully).
- **Schema:** added a `fields` JSON-schema (nullable unions) to `dataset_schema.json` with per-field titles/descriptions; `year` and `authorCount` render as numbers in the dataset view.
