## Changelog

### 2026-09-20

- Fixed the intermittent failures behind the "Under maintenance" flag. On a busy day the events feed returns ~11 MB of JSON — about 9,500 markets and 19,000 assets — and every resulting row was collected into one array before a single write, peaking at 447 MB against a 512 MB allocation. Rows are now flushed to the dataset in blocks of 1,000 as they are built, and the allocation was raised, so a heavy day no longer runs the container out of memory.
- No change to inputs, output fields or the data itself; only when rows are written.

### 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

- Proxy now defaults to Apify's automatic group instead of forcing RESIDENTIAL, and the client falls back to a direct connection on its final retry — cheaper, faster, and still resilient to rate limits.
- Added two dropdown filters for the Events Rank feed: event status (active / closed / resolved / all) and sort order (24h volume, liquidity, ending soonest, etc.).
- Empty input `{}` still returns broad data (active events with markets & odds, sports with live scores, and the Twitter signal feed).
- Added a ~4-minute time budget: long Twitter/AI paginations stop, push what's collected, and exit successfully within the quality window.
- Documented every output column with titles/descriptions in the dataset schema.

### 2026-06-28

- Health check passed — actor verified working end-to-end on Apify platform.
- Changelog refreshed for Store quality compliance.

### 2026-06-20

- Maintenance & reliability pass: re-verified end-to-end against live data and confirmed the Actor completes successfully within the 5-minute quality window on the default input.
- Refreshed the prefilled example input and tuned run defaults for faster, lower-cost runs.
