## 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

- **Nothing required.** Removed the mandatory `mode` field (`required: []`). Empty input `{}` now returns data: it runs a sensible default SPARQL query (notable award winners) instead of erroring.
- **In-code default query.** If `sparql` is left blank (or unknown mode is given), the Actor runs a built-in default query, so a raw `{}` run always produces rows even without schema-injected defaults.
- **Language dropdown.** `language` is now a select menu with 30 common language options and human-readable labels.
- **Proxy.** Proxy is optional; when enabled the Actor now falls back to a direct connection on the final retry (public API). No forced datacenter group.
- **Graceful runs.** Mode handlers are wrapped so the top level logs errors instead of hard-failing the run; empty `search`/`entities` inputs warn and exit cleanly rather than erroring.
- **Schemas.** Added a nullable-safe dataset `fields` schema (title + description per field). Output field keys are unchanged.
