### 2026-07-23

*Features*

- Initial release: capture deterministic screenshots of public webpages and compare each run with its persistent visual baseline.
- Measure changed pixels and percentage, evaluate a configurable change threshold, locate changed regions, and generate a highlighted PNG overlay.
- Focus monitoring with crop selectors, masks, hidden elements, fixed viewport settings, and optional Apify Proxy access.
- Store current, baseline, and diff images in a key-value store while returning automation-ready dataset records for schedules and webhooks.
