-## [Unreleased]
+## [0.16.3] - 2022-04-05
+
+### Packaging
+
+- Extend `parking_lot` dependency supported versions to include 0.12. [#2239](https://github.com/PyO3/pyo3/pull/2239)
 
 ### Added
 
-- Add `PYO3_CROSS_PYTHON_IMPLEMENTATION` environment variable for selecting the default cross Python implementation. [#2272](https://github.com/PyO3/pyo3/pull/2272)
-- Add new public `pyo3-build-config` API using the types from `target_lexicon` crate. Deprecate `cross_compiling()`. [#2253](https://github.com/PyO3/pyo3/pull/2253)
-- Allow dependent crates to access config values from `pyo3-build-config` via cargo link dep env vars. [#2092](https://github.com/PyO3/pyo3/pull/2092)
-- Added methods on `InterpreterConfig` to run Python scripts using the configured executable. [#2092](https://github.com/PyO3/pyo3/pull/2092)
-- Added FFI definitions for `PyType_FromModuleAndSpec`, `PyType_GetModule`, `PyType_GetModuleState` and `PyModule_AddType`. [#2250](https://github.com/PyO3/pyo3/pull/2250)
+- Add methods to `pyo3_build_config::InterpreterConfig` to run Python scripts using the configured executable. [#2092](https://github.com/PyO3/pyo3/pull/2092)
+- Add `as_bytes` method to `Py<PyBytes>`. [#2235](https://github.com/PyO3/pyo3/pull/2235)
+- Add FFI definitions for `PyType_FromModuleAndSpec`, `PyType_GetModule`, `PyType_GetModuleState` and `PyModule_AddType`. [#2250](https://github.com/PyO3/pyo3/pull/2250)
+- Add `pyo3_build_config::cross_compiling_from_to` as a helper to detect when PyO3 is cross-compiling. [#2253](https://github.com/PyO3/pyo3/pull/2253)
+- Add `#[pyclass(mapping)]` option to leave sequence slots empty in container implementations. [#2265](https://github.com/PyO3/pyo3/pull/2265)
 - Add `PyString::intern` to enable usage of the Python's built-in string interning. [#2268](https://github.com/PyO3/pyo3/pull/2268)
 - Add `intern!` macro which can be used to amortize the cost of creating Python strings by storing them inside a `GILOnceCell`. [#2269](https://github.com/PyO3/pyo3/pull/2269)
+- Add `PYO3_CROSS_PYTHON_IMPLEMENTATION` environment variable for selecting the default cross Python implementation. [#2272](https://github.com/PyO3/pyo3/pull/2272)
 
 ### Changed
 
-- Make `PYO3_CROSS_LIB_DIR` environment variable optional when cross compiling. [#2241](https://github.com/PyO3/pyo3/pull/2241)
 - Allow `#[pyo3(crate = "...", text_signature = "...")]` options to be used directly in `#[pyclass(crate = "...", text_signature = "...")]`. [#2234](https://github.com/PyO3/pyo3/pull/2234)
+- Make `PYO3_CROSS_LIB_DIR` environment variable optional when cross compiling. [#2241](https://github.com/PyO3/pyo3/pull/2241)
 - Mark `METH_FASTCALL` calling convention as limited API on Python 3.10. [#2250](https://github.com/PyO3/pyo3/pull/2250)
+- Deprecate `pyo3_build_config::cross_compiling` in favour of `pyo3_build_config::cross_compiling_from_to`. [#2253](https://github.com/PyO3/pyo3/pull/2253)
 
 ### Fixed
 
 - Fix `abi3-py310` feature: use Python 3.10 ABI when available instead of silently falling back to the 3.9 ABI. [#2242](https://github.com/PyO3/pyo3/pull/2242)
-- Considered `PYTHONFRAMEWORK` when cross compiling in order that on macos cross compiling against a [Framework bundle](https://developer.apple.com/library/archive/documentation/MacOSX/Conceptual/BPFrameworks/Concepts/FrameworkAnatomy.html) is considered shared. [#2233](https://github.com/PyO3/pyo3/pull/2233)
-- Panic during compilation when `PYO3_CROSS_LIB_DIR` is set for some host/target combinations. [#2232](https://github.com/PyO3/pyo3/pull/2232)
-- Correct dependency version for `syn` to require correct minimal patch version 1.0.56. [#2240](https://github.com/PyO3/pyo3/pull/2240)
