## Changelog

Output fields are never removed or redefined; changes only add. Newest first.

### 0.2.0

#### Added

- `dailyHistory` now works: with `interest_over_time` and a range longer than ~260 days it returns daily rows (`granularity: "day"`, `isRescaled: true`) built from overlapping 250-day windows. See the README section "Daily history" for accuracy and cost.
- Start-of-run log with the estimated number of queries and a warning when the estimated rows exceed `maxRows`.

#### Changed

- 429 backoff extended to 2, 5, 12, 25 and 45 seconds (about 90 s) before a query is given up. Failed queries are still not charged.

### 0.1.5

#### Added

- Input `skipEmptyRows` (default `true`): rows without data (`value: null`) are not added to the dataset. They are never charged.
- `run_summary.rowsWithoutData`: number of rows Google returned without data.
- The final status message and `run_summary.message` now report how many rows were billed and how many had no data.
- Country/region codes in `geo` and `trendingGeo` are validated before any request (`invalid geo code ...`), so a typo no longer spends proxy traffic.

#### Changed

- `keywords` now has a schema default (`["chatgpt"]`), so an empty input `{}` runs successfully.
- All user-facing messages (status, input errors, warnings, summary, logs) are in English.
- `interest_by_region` rows from `CITY` queries carry `regionCode: null` (cities have no code).

#### Fixed

- Pay-per-event: the number of billed rows was counted twice internally (the SDK also counts a synthetic dataset-item event), which made `rowsWithoutData`-style summaries and `maxRows` wrong. Customers were charged correctly by the platform; only the Actor's own count (summary `rows`, status message and the `maxRows` cut) was off.
- `maxRows` could be exceeded when several queries finished at the same time.
- Dependency `basic-ftp` updated to fix a high-severity advisory.

### 0.1.0 - 0.1.4

First private builds: `interest_over_time`, `interest_by_region`, `related_queries`, `related_topics` (Google currently returns no data), `trending_now`; anchor-based comparison of more than 5 keywords.
