This release contains a number of quality improvements building upon PyO3 0.22.2.
Python function calls (using .call0(), .call1(args) and .call(args, kwargs)) will now make use of the "vectorcall" calling conventions where possible, which can reduce overheads in many cases.
There have been several fix-ups to PyO3's FFI definitions. A new pyo3::ffi::compat namespace has been added which offers some backwards-compatible implementations of Python APIs otherwise normally only available on recent Pythons.
There have been numerous other bug-fixes and minor tweaks to improve user experience.
Thank you to the following contributors for the improvements:
Fix compile failure in declarative #[pymodule] under presence of #![no_implicit_prelude]. #4328
Fix use of borrowed reference in PyDict::get_item (unsafe in free-threaded Python). #4355
Fix #[pyclass(eq)] macro hygiene issues for structs and enums. #4359
Fix hygiene/span issues of '#[pyfunction] and #[pymethods] generated code which affected expansion in macro_rules context. #4382
Fix unsafe_code lint error in #[pyclass] generated code. #4396
Fix async functions returning a tuple only returning the first element to Python. #4407
Fix use of borrowed reference in PyList::get_item (unsafe in free-threaded Python). #4410
Correct FFI definition PyArg_ParseTupleAndKeywords to take *const *const c_char instead of *mut *mut c_char on Python 3.13 and up. #4420
Fix a soundness bug with PyClassInitializer: panic if adding subclass to existing instance via PyClassInitializer::from(Py<BaseClass>).add_subclass(SubClass). #4454
Fix illegal reference counting op inside implementation of __traverse__ handlers. #4479
