The following test fails on this branch, but passes on def test_plugin_prebuilt_recursive_model_validator_runs_once() -> None:
calls: list[None] = []
class CustomOnValidatePython(ValidatePythonHandlerProtocol):
def on_enter(self, input, **kwargs) -> None:
pass
class Plugin:
def new_schema_validator(self, schema, schema_type, schema_type_path, schema_kind, config, plugin_settings):
return CustomOnValidatePython(), None, None
with install_plugin(Plugin()):
class Node(BaseModel):
child: Node | None = None
@model_validator(mode='after')
def validate_model(self) -> Node:
calls.append(None)
return self
class Outer(BaseModel):
node: Node
Outer.model_validate({'node': {}})
assert calls == [None]FWIW this looks like another flavour of pydantic/pydantic-core#1660 and part of the reason why the existing prebuilt stuff is so conservative. |

Apart from the usual bug and maintenance work, there are a number of StringDType related fixes for problems discovered during the ongoing string work in the main branch. This release supports Python versions 3.12-3.15 #### Changes - Casting a fixed-width byte string array (`np.bytes_`) to `StringDType` now raises `TypeError` when the bytes are not valid UTF-8. Previously the invalid bytes were stored as-is and later caused undefined behavior in string operations. ([gh-32296](numpy/numpy#32296)) - `MaskedArray._fill_value` would become stale when ufuncs that change dtype left the result holding a fill\_value typed for the old dtype. The mismatch was silent until something later called `_check_fill_value`, such as `.view()`, and then a `TypeError` would be raised. Now, when the copied fill\_value is no longer valid for the new dtype, fall back to the default fill\_value for that dtype instead of propagating the stale value. This may raise a `ComplexWarning` if the fill\_value is complex and the new dtype is real. ([gh-32423](numpy/numpy#32423)) #### Contributors A total of 9 people contributed to this release.
