Now they generate a separate wrapper model using the title name, and the field references this wrapper type (e.g., <code>ProcessingStatusUnionTitle | None</code>). This affects code that directly accesses union field values, as they now need to access the <code>.root</code> attribute (Pydantic v2) or <code>.__root__</code> (Pydantic v1) of the wrapper model. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/2889";>#2889</a>) <strong>Before:</strong> <pre lang="python"><code>class ProcessingTaskTitle(BaseModel): processing_status_union: ( ProcessingStatusDetail | ExtendedProcessingTask | ProcessingStatusTitle | None ) = Field('COMPLETED', title='Processing Status Union Title') </code></pre> <strong>After:</strong> <pre lang="python"><code>class ProcessingStatusUnionTitle(BaseModel): __root__: ( ProcessingStatusDetail | ExtendedProcessingTask | ProcessingStatusTitle ) = Field(..., title='Processing Status Union Title') class ProcessingTaskTitle(BaseModel): processing_status_union: ProcessingStatusUnionTitle | None = Field( default_factory=lambda: ProcessingStatusUnionTitle.parse_obj('COMPLETED'), title='Processing Status Union Title', ) </code></pre> </li> <li>Inline types with titles now generate named type aliases when <code>--use-title-as-name</code> is enabled - Arrays, dicts, enums-as-literals, and oneOf/anyOf unions that have a <code>title</code> in the schema now generate named type aliases or RootModel classes instead of being inlined. This improves readability but changes the generated type structure. For TypedDict output, generates <code>type MyArrayName = list[str]</code>. For Pydantic output, generates <code>class MyArrayName(RootModel[list[str]])</code>. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/2889";>#2889</a>)</li> <li>Default value handling changed for wrapped union fields - Fields that previously had simple default values now use <code>default_factory</code> with a lambda that calls <code>parse_obj()</code> (Pydantic v1) or <code>model_validate()</code> (Pydantic v2) to construct the wrapper model. Code that introspects field defaults will see a factory function instead of a direct value. (<a href="https://redirect.github.com/koxudaxi/datamodel-code-generator/issues/2889";>#2889</a>)</li> <li>Different output for <code>$ref</code> with <code>nullable: true</code> - When a JSON Schema property has a <code>$ref</code> combined with only <code>nullable: true</code> (and optionally metadata like <code>title</code>/<code>description</code>), the generator now uses the referenced type directly with <code>Optional</code> annotation instead of creating a new merged model. For example, a schema with multiple properties referencing <code>User</code> with <code>nullable: true</code> will now generate <code>user_a: User | None</code> instead of creating separate <code>UserA</code>, <code>UserB</code> model classes. This is a bug fix that reduces redundant model generation, but existing code that depends on the previously generated class names will break.
