+## 4.79.2
+**`(fix):`** Fix AsyncAPI bundler silently degrading typed models to `unknown` when

 ## 4.79.1
 **`(fix):`** Fix auto-detected global headers generating type-incorrect example values. When headers like `Request-Timeout` (integer type) were auto-promoted to global headers, the example generator used the header name as a string value instead of skipping the example.
