## Changelog

### 2026-09-16

- Add first-post fetch, first dataset write, SDK startup, and dataset/charging timing measurements to OUTPUT.
- Correct hosted pay-per-event summary counts by tracking the custom result event separately from synthetic dataset events.
- Check the available event budget before writing a paid batch.
- Start Node directly in the container to remove the extra npm process.
- Use 1 GB default memory after repeated hosted tests showed earlier results than 512 MB; keep concurrency at 20.

### 2026-09-15

- Compare all returned timestamps so an older pinned post cannot automatically win.
- Try direct API recovery before residential proxies, skip unnecessary recovery after direct API 404s, and recover blocked API responses through residential embeds.
- Fix custom proxies configured with useApifyProxy disabled and rotate sessions per profile.
- Reject oversized input explicitly and distinguish incomplete responses from genuinely empty timelines.
- Add activity age, user IDs, optional engagement fields, request counts, and machine-readable errors.
- Keep private and empty-profile diagnostics free; report active runtime pricing and apply backpressure to dataset writes.
- Reduce default run memory to 512 MB; add a quick start, API export guide, monitoring recipes, and troubleshooting.

### 2026-09-02

- Replaced browser automation with a lightweight HTTP-first extraction pipeline.
- Added residential proxy fallback with rotating sessions and direct retry recovery.
- Added bounded concurrency, timeouts, retries, deduplication, and support for 1,000 profiles.
- Streamed results continuously through efficient micro-batched dataset writes.
- Added clean dataset views, output schema links, run summaries, and richer profile/post metadata.
- Added spending-limit-safe pay-per-result billing at $2 per 1,000 successful results, effective September 16, 2026; Apify platform usage remains separate.
