## Changelog

### 2026-08-24 — Reliability

- Fixed the prefilled input so automated and one-click runs explicitly confirm authorized use while the runtime continues to reject missing or false confirmation.

### 2026-08-23 — 0.1.0

- Added the initial YouTube Authorized 4K Video Downloader input, output, and measured volume-based pricing contracts.
- Extract and download each video in one session so short-lived YouTube media URLs remain valid.
- Stream MP4, WebM, and Matroska media to cloud storage with an explicit file length.
- Bootstrap the pinned yt-dlp and BotGuard provider automatically for reproducible local `apify run` execution.
