## 4.79.4

**`(fix):`** Resolve `$ref` pointers to external markdown files inside OpenAPI `description`
fields by inlining the file contents as a string at spec load time. Previously
such specs failed with `e.replace is not a function` during SDK generation.

## 4.79.3

**`(fix):`** Support `x-fern-discriminator-context` extension on OpenAPI discriminator objects and auto-infer
`protocol` context for SSE-shaped discriminated unions.

## 4.79.2

**`(fix):`** Fix AsyncAPI bundler silently degrading typed models to `unknown` when
multi-file specs use file-local `$ref` pointers (e.g. `$ref: '#/Sibling'`)
inside schemas that are inlined from external files.

## 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.
