v0.3.0¶

Release Date: 2026-07-19

Adds the render.AvatarLister capability and shared render helpers, supporting provider adapters that live in the provider SDK repositories.

Highlights¶

render.AvatarLister capability so render providers can enumerate an account's avatars, returning generation-ready IDs

render.AvatarLister optional capability interface (with render.AvatarInfo) for avatar discovery — feature-detected like render.AudioUploader. Useful because a provider's listing endpoint may return different identifiers than its generation endpoint accepts (e.g. HeyGen v3 avatar groups vs. v2 avatar IDs)
render.AudioContentType helper: audio MIME type from a filename, for AudioUploader implementations
render.DownloadURL helper: stream a URL to an io.Writer, for Provider.Download implementations

Both helpers are stdlib-only; sharing them here keeps per-provider adapters (in the SDK repos) from duplicating them.
