## Changelog

### 0.1 — 2026-10-12

Initial release.

- Export earthquakes from the USGS ComCat catalog (FDSN Event Web Service) by time window, rectangle (also across the date line) or circle, magnitude, depth, event type, review status and PAGER alert.
- One row per event: time, coordinates, depth, magnitude and type, place, status, tsunami flag, felt reports, CDI/MMI, PAGER alert, significance, all event IDs and USGS links.
- Sort by newest, oldest or largest, up to 500 events per run; truncation is reported with the total at the source.
- Long windows are read in narrow slices first; overloaded windows are split in half.
- Change monitoring with `monitorKey` or `previousDatasetId`: new, revised (with changed fields and previous values), deleted and unchanged events; `onlyChanges` writes only the changes.
