v0.9.0 (2026-10-06)

No breaking changes since v0.8.1. video-agent send --message is now optional.

Template authoring. Create a template from one of your videos with template create, rename it with template update, declare its variables with template variables update, and remove it with template delete. (#418)
Instant Video. Generate a video directly from text, an image, or a reference with model videos create, and check on it with model videos get. (#396)
HeyGen Voice (model group). Train professional voice clones and synthesize speech with model audio voices create|list|get|delete and model audio tts create. (#364)
Avatar Look Packs. Generate new looks for an avatar with avatar looks create, choosing from avatar look-templates list. (#364)
Translation proofreads. List and delete video-translation proofreads with video-translate proofreads list|delete. (#364)
Folders. Create a folder with folder create and inspect one with folder get. (#396)
Safe retries with --idempotency-key. Create commands that accept an Idempotency-Key now expose it as a flag, so a retried request does not create a duplicate resource. (#365)
heygen update --check. Reports whether an update is available, and whether this build can be updated, without installing anything. (#366)
More request options. voice speech create gains --engine and --force-regenerate, and video-agent create gains --visibility and --members. (#364, #396, #418)

auth status shows API key details. For an API key it now reports the key's name, status, scopes and expiry, and still works for keys without account read access. (#333)

heygen update no longer downgrades local builds. A binary built from source is no longer offered an older release as an "update". (#366)
