v0.8.16

# HyperFrames v0.8.16

Released on 2026-08-27.

Rendering is more reliable across audio, embedded sources, long sequences, and empty caches, while CJK and Thai captions keep phrase boundaries. Local video generation now avoids dead model tiers, and the player can retain runtime data channels for richer integrations.

## Features

- **Player:** Add retained runtime data channels ([4f00336c9](https://github.com/heygen-com/hyperframes/commit/4f00336c92f6418aab82c060853da604dd832197), [#3471](https://github.com/heygen-com/hyperframes/pull/3471)).
