+>
+Preview publishers can now use the same deterministic font resolver as final renders, preventing CSS case transforms from changing typography between preview and export. Rendering now exits stalled parallel capture paths, while template editing and JSON attribute linting handle promoted media and encoded values more safely.
+
+## Features
+
+- **CLI:** Stamp font compiler version in localized HTML ([d6de08341](https://github.com/heygen-com/hyperframes/commit/d6de083411d76a0819768b21d30a305500a92048)).
+- **CLI:** Expose deterministic font localization ([38f8f9250](https://github.com/heygen-com/hyperframes/commit/38f8f9250a3f2a551a2e0a5f685ac4f64109e218)).
+
+## Fixes
+
+- **Fonts:** Harden localizer release diagnostics ([7c40efbc6](https://github.com/heygen-com/hyperframes/commit/7c40efbc62bd7bd70bcfdb80cd55aef4bafb39d6)).
+- **CLI:** Keep font localizer process ownership explicit ([ec68d40cc](https://github.com/heygen-com/hyperframes/commit/ec68d40cc617272943069123383e7a9f6e463e93)).
+- **Fonts:** Cover rendered case variants in subsets ([744146eb6](https://github.com/heygen-com/hyperframes/commit/744146eb6e71f3c108091fe981a7d63859a6287b)).
+- **Producer:** Trip DE parallel-router circuit breaker on stalls and hangs ([3202f3fb8](https://github.com/heygen-com/hyperframes/commit/3202f3fb87e0f7babfdfe0a9d62703b293abfd80), [#3479](https://github.com/heygen-com/hyperframes/pull/3479)).
+- **Lint:** Decode JSON attribute entities ([3cacac5bd](https://github.com/heygen-com/hyperframes/commit/3cacac5bdc405b808e74df3da14e6c1595357325)).
+- Document safe template default editing ([71e8e92ae](https://github.com/heygen-com/hyperframes/commit/71e8e92ae940584a2be5a82c5a3d102187043dea)).
