Breaking Changes

Python Version

• Python 3.9 support dropped - Minimum Python version is now 3.10+ (#2692)

Default Behavior Changes

• Native type hints by default - list[...]/dict[...] are now used instead of List[...]/Dict[...]. Use --no-use-standard-collections to restore previous behavior (#2699)
• Union operator by default - X | Y syntax is now used instead of Union[X, Y]/Optional[X]. Use --no-use-union-operator to restore previous behavior (#2703)

Code Generation Changes

• Nullable required fields no longer have default values (Pydantic v2) - Fields marked as both required and nullable no longer get = None. The pydantic_v2/BaseModel.jinja2 template logic was updated to only assign default values when field.required is false. This fixes incorrect behavior where required fields could be omitted (#2520)
• TypedDict respects enum_field_as_literal setting - TypedDict output now respects user's --enum-field-as-literal setting instead of forcing all. Added new --enum-field-as-literal none option (#2691)
• prefixItems now generates tuple types - JSON Schema prefixItems with matching minItems/maxItems and no items now generates tuple[T1, T2, ...] instead of list[...]. This applies when the array has a fixed length with heterogeneous types (#2537)
