## 4.43.2

**`(fix):`** Fix OpenAPI importer to produce optional response types when an endpoint
has both a 200 (with body) and a 204 (No Content) response. Previously the
204 response was silently ignored, causing generators to emit non-nullable
return types and attempt deserialization on empty bodies. Both the v3 parser
and v3.1 importer paths are fixed.

## 4.43.1

**`(fix):`** Fix OpenAPI importer stripping the discriminant property from shared
`allOf` base schemas when they are used by `oneOf` discriminated union
variants. Previously, if a base schema like `Error` was extended by both
union members and standalone schemas, the discriminant property (e.g.
`code`) would be removed from the base, causing downstream `fern check`
errors on the union variant types.

## 4.42.1

**`(fix):`** Strip MDX comments (`{/* ... */}`) from markdown.
