## Changelog

All notable changes to the YouTube Channel ID Extractor are documented here.

### \[2.1.0] - 2026-08-31

#### QA hardening

- Added strict bounded input validation, canonical request deduplication, shorts/embed/live URL support, five unit tests, and fail-closed dataset validation.
- Corrected the public-link and provenance schemas to match emitted objects.
- Made direct browsing the default, made explicit proxy failures strict, and removed inconsistent non-Chromium fingerprints.
- Removed unused filters, utilities, error modules, and a packaged continuation log; switched Docker installs to deterministic `npm ci`.

### \[2.0.0] - 2026-07-29

#### Changed

- Rebuilt identity resolution around public YouTube channel pages and public video-owner metadata.
- Added strict support for handles, UC IDs, canonical and legacy channel URLs, and public video URLs.
- Added source provenance, rich public evidence, recursive output cleaning, strict zero-result failure, five browser fingerprints, bounded retries, and proxy-session rotation.
- Replaced invalid dataset field definitions with an Apify-compatible dataset view and added recursive local dataset validation.

#### Changed

- Added modular `src/errors/` module (ScraperError, ErrorTypes, ErrorHandler) following Brave actor pattern
