Release Notes

pyo3/pyo3 (pyo3)

v0.29.2: PyO3 0.29.2

Compare Source

This patch fixes a regression in PyO3 0.29.1 which broke PyPy 3.11 compatibility (#[pyclass] types would crash PyPy on instance deletion).

A few further fixes have also landed with similar themes to PyO3 0.29.1: fixes to minor reference counting bugs, rough edges which would cause crashes, issues which would cause failed builds, and fixes to experimental-inspect type stub generation.

For a full list of the exact fixes please consult the CHANGELOG.

Changed

• Use the inline definition of Py_TYPE in the unlimited API on 3.14+ #​6179

Fixed

• Fix incorrect pointer arithmetic in FFI definitions PyObject_GET_WEAKREFS_LISTPTR and PyHeapType_GET_MEMBERS. #​6145
• Fix compilation error with nightly feature on PyPy and GraalPy due to !Ungil implementations for FFI types not available on those platforms. #​6146
• Fix append_to_inittab and PyInit_<module> internal module definition corruption on 32-bit and big-endian platforms on Python 3.15+. #​6150
• Fix return value of PyClassGuardMutSuper::as_super being scoped to the full guard lifetime, now the &mut borrow of the as_super() call. #​6181
• Fix builds for free-threaded interpreters older than 3.15 erroring with "cannot set a minimum Python version" when an abi3t-py3* feature is enabled and the configuration comes from PYO3_CONFIG_FILE, sysconfigdata or cross-compilation defaults. #​6192
• Fix a memory leak when deallocating #[pyclass(dict)] instances with a populated __dict__. #​6198
• Fix an abort inside a #[pyclass]'s GC traversal when the traversal is stopped early. #​6206
• Fix reference cycles through the __dict__ of a #[pyclass(dict)] never being collected. #​6206
• Fix building on GraalPy 3.13. #​6208
• Fix reference count leak of references to #[pyclass] type objects held by their instances on instance deallocation. #​6224
• Fix FFI definitions PyByteArray_GET_SIZE, PyList_GET_SIZE, and PySet_GET_SIZE to use an atomic load for free-threaded Python. #​6230
• Fix a memory leak on Python 3.11 and 3.12 where creating an instance of a #[pyclass(dict)] class leaked one empty dict per instance. #​6234
• Fix experimental-inspect type stubs to emit the arguments of many magic methods as positional-only to match runtime behavior, rather than positional-or-keyword. #​6239
• Fix experimental-inspect type stubs to emit the Python name rather than the Rust name for #[pyfunction(name = "...")]. #​6254
• Fix experimental-inspect generating invalid internal JSON when #[pymodule] members are gated by #[cfg]. #​6255
• Fix __inplace_concat__ and __inplace_repeat__ overriding __concat__ and __repeat__ when both were defined. #​6260
• Fix conversion of out-of-range time::Duration values to return OverflowError instead of panicking. #​6266
• Fix experimental-inspect type stubs padding blank lines inside indented docstrings. #​6270
