+## [0.22.4] - 2024-10-12
+
+### Added
+
+- Add FFI definition `PyWeakref_GetRef` and `compat::PyWeakref_GetRef`. [#4528](https://github.com/PyO3/pyo3/pull/4528)
+
+### Changed
+
+- Deprecate `_borrowed` methods on `PyWeakRef` and `PyWeakrefProxy` (just use the owning forms). [#4590](https://github.com/PyO3/pyo3/pull/4590)
+
+### Fixed
+
+- Revert removal of private FFI function `_PyLong_NumBits` on Python 3.13 and later. [#4450](https://github.com/PyO3/pyo3/pull/4450)
+- Fix `__traverse__` functions for base classes not being called by subclasses created with `#[pyclass(extends = ...)]`. [#4563](https://github.com/PyO3/pyo3/pull/4563)
+- Fix regression in 0.22.3 failing compiles under `#![forbid(unsafe_code)]`. [#4574](https://github.com/PyO3/pyo3/pull/4574)
+- Workaround possible use-after-free in `_borrowed` methods on `PyWeakRef` and `PyWeakrefProxy` by leaking their contents. [#4590](https://github.com/PyO3/pyo3/pull/4590)
+- Fix crash calling `PyType_GetSlot` on static types before Python 3.10. [#4599](https://github.com/PyO3/pyo3/pull/4599)
