3.11.5
(fix): Extract error body parsing to ObjectMappers.parseErrorBody() utility method. When servers return XML/HTML errors instead of JSON, the utility gracefully falls back to raw string instead of throwing JsonProcessingException, preserving HTTP status codes and error details.
3.11.4
(fix): The NullableNonemptyFilter now correctly handles OptionalNullable.isAbsent() to exclude absent fields from JSON serialization in PATCH requests.
