Release Notes

pyo3/pyo3 (pyo3)

v0.26.0

Compare Source

Packaging

• Bump hashbrown dependency to 0.15. #​5152
• Update MSRV to 1.74. #​5171
• Set the same maximum supported version for alternative interpreters as for CPython. #​5192
• Add optional bytes dependency to add conversions for bytes::Bytes. #​5252
• Publish new crate pyo3-introspection to pair with the experimental-inspect feature. #​5300
• The PYO3_BUILD_EXTENSION_MODULE now causes the same effect as the extension-module feature. Eventually we expect maturin and setuptools-rust to set this environment variable automatically. Users with their own build systems will need to do the same. #​5343

Added

• Add #[pyo3(warn(message = "...", category = ...))] attribute for automatic warnings generation for #[pyfunction] and #[pymethods]. #​4364
• Add PyMutex, available on Python 3.13 and newer. #​4523
• Add FFI definition PyMutex_IsLocked, available on Python 3.14 and newer. #​4523
• Add PyString::from_encoded_object. #​5017
• experimental-inspect: add basic input type annotations. #​5089
• Add FFI function definitions for PyFrameObject from CPython 3.13. #​5154
• experimental-inspect: tag modules created using #[pymodule] or #[pymodule_init] functions as incomplete. #​5207
• experimental-inspect: add basic return type support. #​5208
• Add PyCode::compile and PyCodeMethods::run to create and execute code objects. #​5217
• Add PyOnceLock type for thread-safe single-initialization. #​5223
• Add PyClassGuard(Mut) pyclass holders. In the future they will replace PyRef(Mut). #​5233
• experimental-inspect: allow annotations in #[pyo3(signature)] signature attribute. #​5241
• Implement MutexExt for parking_lot's/lock_api ReentrantMutex. #​5258
• experimental-inspect: support class associated constants. #​5272
• Add Bound::cast family of functions superseding the PyAnyMethods::downcast family. #​5289
• Add FFI definitions Py_Version and Py_IsFinalizing. #​5317
• experimental-inspect: add output type annotation for #[pyclass]. #​5320
• experimental-inspect: support #[pyclass(eq, eq_int, ord, hash, str)]. #​5338
• experimental-inspect: add basic support for #[derive(FromPyObject)] (no struct fields support yet). #​5339
• Add Python::try_attach. #​5342

Changed

• Use Py_TPFLAGS_DISALLOW_INSTANTIATION instead of a __new__ which always fails for a #[pyclass] without a #[new] on Python 3.10 and up. #​4568
• PyModule::from_code now defaults file_name to <string> if empty. #​4777
• Deprecate PyString::from_object in favour of PyString::from_encoded_object. #​5017
• When building with abi3 for a Python version newer than pyo3 supports, automatically fall back to an abi3 build for the latest supported version. #​5144
• Change is_instance_of trait bound from PyTypeInfo to PyTypeCheck. #​5146
• Many PyO3 proc macros now report multiple errors instead of only the first one. #​5159
• Change MutexExt return type to be an associated type. #​5201
• Use PyCallArgs for Py::call and friends so they're equivalent to their Bound counterpart. #​5206
• Rename Python::with_gil to Python::attach. #​5209
• Rename Python::allow_threads to Python::detach #​5221
• Deprecate GILOnceCell type in favour of PyOnceLock. #​5223
• Rename pyo3::prepare_freethreaded_python to Python::initialize. #​5247
• Convert PyMemoryError into/from io::ErrorKind::OutOfMemory. #​5256
• Deprecate GILProtected. #​5285
• Move #[pyclass] docstring formatting from import time to compile time. #​5286
• Python::attach will now panic if the Python interpreter is in the process of shutting down. #​5317
• Add fast-path to PyTypeInfo::type_object for #[pyclass] types. #​5324
• Deprecate PyObject type alias for Py<PyAny>. #​5325
• Rename Python::with_gil_unchecked to Python::attach_unchecked. #​5340
• Rename Python::assume_gil_acquired to Python::assume_attached. #​5354

Removed

• Remove FFI definition of internals of PyFrameObject. #​5154
• Remove Eq and PartialEq implementations on PyGetSetDef FFI definition. #​5196
• Remove private FFI definitions _Py_IsCoreInitialized and _Py_InitializeMain. #​5317

Fixed

• Use critical section in PyByteArray::to_vec on freethreaded build to replicate GIL-enabled "soundness". #​4742
• Fix precision loss when converting bigdecimal into Python. #​5198
• Don't treat win7 target as a cross-compilation. #​5210
• WASM targets no longer require exception handling support for Python < 3.14. #​5239
• Fix segfault when dropping PyBuffer<T> after the Python interpreter has been finalized. #​5242
• experimental-inspect: better automated imports generation. #​5251
• experimental-inspect: fix introspection of __richcmp__, __concat__, __repeat__, __inplace_concat__ and __inplace_repeat__. #​5273
• fixed a leaked borrow, when converting a mutable sub class into a frozen base class using PyRef::into_super #​5281
• Fix FFI definition Py_Exit (never returns, was () return value, now !). #​5317
• experimental-inspect: fix handling of module members gated behind #[cfg(...)] attributes. #​5318
