## 3.18.4

**`(fix):`** Revert regex parsing of `<Code>` components.

## 3.18.3

**`(fix):`** Fix duplicate type declarations when OpenAPI specs use `allOf` references in inline request bodies.

## 3.18.2

**`(fix):`** Remove `fern check` validation rule that rejected HEAD endpoints with response bodies. HEAD endpoints can now define response bodies without triggering validation errors.

## 3.18.1

**`(fix):`** Fix `fern check` errors when OpenAPI specs use `allOf` with multiple schemas that share the same property names in inline request bodies. The OpenAPI importer now correctly inlines conflicting schemas instead of extending them, preventing duplicate property errors.
