## Changelog

### 2026-09-22

*Reliability*

- Keyword discovery now requests channel-only results, and channel URLs or handles entered in the search field are resolved directly instead of ending the run with no results.

### 2026-09-21

*Reliability*

- Large channel lists now retain the default five active workers, reducing timeout risk while preserving the memory guard and all requested channels.

### 2026-09-20

*Reliability*

- Large channel lists now use memory-safe concurrency and report batch progress, reducing out-of-memory risk while preserving all requested channels.

### 2026-09-13

*Reliability*

- Temporary YouTube timeouts, rate limits, and server errors are now retried with bounded backoff; permanent request errors still fail fast.

### 2026-08-30

*Features*

- Added optional anonymous keyword discovery with `searchQueries` and `maxChannelsPerQuery`, plus auditable `sourceType` and `sourceQuery` output fields.

### 2026-05-27

*Features*

- Initial public release with YouTube channel email discovery, channel metadata, and linked social profile extraction.
