## Unreleased
## [0.16.4] - 2022-04-14
### Added
- Add `PyTzInfoAccess` trait for safe access to time zone information. [#2263](https://github.com/PyO3/pyo3/pull/2263)

#### Building `abi3` extensions without a Python interpreter
As an advanced feature, you can build PyO3 wheel without calling Python interpreter with the environment variable `PYO3_NO_PYTHON` set.
Also, if the build host Python interpreter is not found or is too old or otherwise unusable,
PyO3 will still attempt to compile `abi3` extension modules after displaying a warning message.
On Unix-like systems this works unconditionally; on Windows you must also set the `RUSTFLAGS` environment variable
to contain `-L native=/path/to/python/libs` so that the linker can find `python3.lib`.
