## Changelog

All notable changes to the YouTube Video Description Extractor are documented here.

### \[2.1.0] - 2026-09-08

#### Changed

- Replaced browser automation and private endpoint assumptions with public YouTube watch-page HTML parsing.
- Added strict input controls, deduplication, bounded retries/delay/timeout, optional diagnostics, and standard Apify Proxy routing.
- Expanded the dataset with description links, hashtags, tags, channel identity, subscriber text, thumbnails, statistics, dates, category, safety, and live-state fields.
- Added an `OUTPUT` run summary, rich dataset schema, contract tests, and cross-checking dataset validator.

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

#### Changed

- Replaced DOM “Show more” extraction with source-provided embedded metadata.
- Added strict canonical YouTube URL/ID validation and bounded retries.
