+- Add `#[pyclass(hash)]` option to implement `__hash__` in terms of the `Hash` implementation [#4206](https://github.com/PyO3/pyo3/pull/4206)
+- Add `#[pyclass(eq)]` option to generate `__eq__` based on `PartialEq`, and `#[pyclass(eq_int)]` for simple enums to implement equality based on their discriminants. [#4210](https://github.com/PyO3/pyo3/pull/4210)
+- Implement `From<Bound<'py, T>>` for `PyClassInitializer<T>`. [#4214](https://github.com/PyO3/pyo3/pull/4214)

+- Implement `PartialEq<str>` for `Bound<'py, PyString>`. [#4245](https://github.com/PyO3/pyo3/pull/4245)
+- Implement `PyModuleMethods::filename` on PyPy. [#4249](https://github.com/PyO3/pyo3/pull/4249)
+- Add `pyo3_ffi::c_str` macro to create `&'static CStr` on Rust versions which don't have 1.77's `c""` literals. [#4255](https://github.com/PyO3/pyo3/pull/4255)
+- Support `bool` conversion with `numpy` 2.0's `numpy.bool` type [#4258](https://github.com/PyO3/pyo3/pull/4258)
+
+### 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)
+- 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)
+- `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 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)
