+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)).
+
+## Fixes
+
+- **Media Use:** Repoint the dead videogen tier, demote past unusable local models ([8392e84a1](https://github.com/heygen-com/hyperframes/commit/8392e84a1839dbe083b74d093cb441f4610389c4), [#3509](https://github.com/heygen-com/hyperframes/pull/3509)).
+- **Engine:** Stop destroying the AAC priming edit list when muxing ([ee64c3b11](https://github.com/heygen-com/hyperframes/commit/ee64c3b1168a3466269344197ba6774f9eb15e14), [#3505](https://github.com/heygen-com/hyperframes/pull/3505)).
+- **CLI:** Keep phrase-level CJK and Thai transcripts as separate cues ([18409c9f2](https://github.com/heygen-com/hyperframes/commit/18409c9f2742e491ef7ff6a1454675a295e5d0a0), [#3436](https://github.com/heygen-com/hyperframes/pull/3436)).
+- **Engine,producer,lint:** Resolve \<source\> children for media extract and localize ([97991bbd3](https://github.com/heygen-com/hyperframes/commit/97991bbd3566a70f857412739dfa6ca9acfcaf27), [#3238](https://github.com/heygen-com/hyperframes/pull/3238)).
+- **Engine:** Preserve source frame identity above 99,999 ([c9f43ebcf](https://github.com/heygen-com/hyperframes/commit/c9f43ebcfbc05a83b18f46007f31a5cbd973ebb9), [#3503](https://github.com/heygen-com/hyperframes/pull/3503)).
+- **Studio:** Dedupe repeated selection telemetry ([9aaa7552f](https://github.com/heygen-com/hyperframes/commit/9aaa7552fc7a41d479e4b4638cd0c47472652ddc), [#3498](https://github.com/heygen-com/hyperframes/pull/3498)).
+- **Engine:** Treat a sentineled cache entry with no frames as a miss ([dae5b7b90](https://github.com/heygen-com/hyperframes/commit/dae5b7b90b7eefceffc9e64cc532b5cc74eeeedd), [#3434](https://github.com/heygen-com/hyperframes/pull/3434)).
+- **Producer,core:** Honor relative data-start id-refs in render media scheduling ([f52ec1c25](https://github.com/heygen-com/hyperframes/commit/f52ec1c25f3af20fcceefad24acb06f37feab24c), [#3252](https://github.com/heygen-com/hyperframes/pull/3252)).
+- **Producer:** Fall back to screenshot capture on drawElement canvas-not-initialized ([a7e867475](https://github.com/heygen-com/hyperframes/commit/a7e86747586b5aad0263b6b00bbd9d32c51ff7e6), [#3480](https://github.com/heygen-com/hyperframes/pull/3480)).
+- **Core:** Evict cached MediaElementSource on src mutation, soften enforcement-point claims ([f7fc0017a](https://github.com/heygen-com/hyperframes/commit/f7fc0017a6a6f31a4ae725f9f391d8dc63e3d9cc)).
+- **Core:** Correct web-audio-route subpath export resolution ([32ef37cfc](https://github.com/heygen-com/hyperframes/commit/32ef37cfc31975afbeae85a3f6805e575a43e87a)).
+- **Core:** Address review — gate early diagnostic, fix empty crossOrigin, document gaps ([acc689825](https://github.com/heygen-com/hyperframes/commit/acc689825543942939bbef14ccd2844b7f13298d)).
+- **Core:** Prevent cross-origin Web Audio capture from silencing audio ([cce17da5a](https://github.com/heygen-com/hyperframes/commit/cce17da5a9eb1c6efa21db084d786a1d34b5d8f9)).
