Change history of /v1.
/v1 is strictly versioned: we only add fields, error codes and optional parameters, and never change existing semantics. Breaking changes ship only in /v2.

- Global site launched (priced in USD)
- Task results add upstream_video_url and upstream_url_expires_at (provided when the account is set to return the upstream URL)

2026-10-30
- First public release: Seedance 2.0 Standard available on the China site
- Multi-channel recovery with an unchanged task ID throughout
- Webhook signature v1 (HMAC-SHA256)
