- Implement `From<Bound<'py, T>>` for `PyClassInitializer<T>`. [#4214](https://github.com/PyO3/pyo3/pull/4214)

- Support `bool` conversion with `numpy` 2.0's `numpy.bool` type [#4258](https://github.com/PyO3/pyo3/pull/4258)
- Add `PyAnyMethods::{bitnot, matmul, floor_div, rem, divmod}`. [#4264](https://github.com/PyO3/pyo3/pull/4264)

### Changed

- Change the type of `PySliceIndices::slicelength` and the `length` parameter of `PySlice::indices()`. [#3761](https://github.com/PyO3/pyo3/pull/3761)
- Deprecate implicit default for trailing optional arguments [#4078](https://github.com/PyO3/pyo3/pull/4078)
- `Clone`ing pointers into the Python heap has been moved behind the `py-clone` feature, as it must panic without the GIL being held as a soundness fix. [#4095](https://github.com/PyO3/pyo3/pull/4095)
- Add `#[track_caller]` to all `Py<T>`, `Bound<'py, T>` and `Borrowed<'a, 'py, T>` methods which can panic. [#4098](https://github.com/PyO3/pyo3/pull/4098)
- Change `PyAnyMethods::dir` to be fallible and return `PyResult<Bound<'py, PyList>>` (and similar for `PyAny::dir`). [#4100](https://github.com/PyO3/pyo3/pull/4100)
- The global reference pool (to track pending reference count decrements) is now initialized lazily to avoid the overhead of taking a mutex upon function entry when the functionality is not actually used. [#4178](https://github.com/PyO3/pyo3/pull/4178)
- Emit error messages when using `weakref` or `dict` when compiling for `abi3` for Python older than 3.9. [#4194](https://github.com/PyO3/pyo3/pull/4194)
- Change `PyType::name` to always match Python `__name__`. [#4196](https://github.com/PyO3/pyo3/pull/4196)
- Remove CPython internal ffi call for complex number including: add, sub, mul, div, neg, abs, pow. Added PyAnyMethods::{abs, pos, neg} [#4201](https://github.com/PyO3/pyo3/pull/4201)
- Deprecate implicit integer comparision for simple enums in favor of `#[pyclass(eq_int)]`. [#4210](https://github.com/PyO3/pyo3/pull/4210)
- Set the `module=` attribute of declarative modules' child `#[pymodule]`s and `#[pyclass]`es. [#4213](https://github.com/PyO3/pyo3/pull/4213)
- Set the `module` option for complex enum variants from the value set on the complex enum `module`. [#4228](https://github.com/PyO3/pyo3/pull/4228)
- Respect the Python "limited API" when building for the `abi3` feature on PyPy or GraalPy. [#4237](https://github.com/PyO3/pyo3/pull/4237)
- Optimize code generated by `#[pyo3(get)]` on `#[pyclass]` fields. [#4254](https://github.com/PyO3/pyo3/pull/4254)
- `PyCFunction::new`, `PyCFunction::new_with_keywords` and `PyCFunction::new_closure` now take `&'static CStr` name and doc arguments (previously was `&'static str`). [#4255](https://github.com/PyO3/pyo3/pull/4255)
- The `experimental-declarative-modules` feature is now stabilized and available by default. [#4257](https://github.com/PyO3/pyo3/pull/4257)

### Fixed

- Fix panic when `PYO3_CROSS_LIB_DIR` is set to a missing path. [#4043](https://github.com/PyO3/pyo3/pull/4043)
- Fix a compile error when exporting an exception created with `create_exception!` living in a different Rust module using the `declarative-module` feature. [#4086](https://github.com/PyO3/pyo3/pull/4086)
- Fix FFI definitions of `PY_VECTORCALL_ARGUMENTS_OFFSET` and `PyVectorcall_NARGS` to fix a false-positive assertion. [#4104](https://github.com/PyO3/pyo3/pull/4104)
- Disable `PyUnicode_DATA` on PyPy: not exposed by PyPy. [#4116](https://github.com/PyO3/pyo3/pull/4116)
- Correctly handle `#[pyo3(from_py_with = ...)]` attribute on dunder (`__magic__`) method arguments instead of silently ignoring it. [#4117](https://github.com/PyO3/pyo3/pull/4117)
- Fix a compile error when declaring a standalone function or class method with a Python name that is a Rust keyword. [#4226](https://github.com/PyO3/pyo3/pull/4226)
- Fix declarative modules discarding doc comments on the `mod` node. [#4236](https://github.com/PyO3/pyo3/pull/4236)
- Fix `__dict__` attribute missing for `#[pyclass(dict)]` instances when building for `abi3` on Python 3.9. [#4251](https://github.com/PyO3/pyo3/pull/4251)
