### History
#### 24.1.0 (2024-06-24)
- Import `os.link` conditionally to fix importing on android.
[#175](https://github.com/Tinche/aiofiles/issues/175)
- Remove spurious items from `aiofiles.os.__all__` when running on Windows.
- Switch to more modern async idioms: Remove types.coroutine and make AiofilesContextManager an awaitable instead a coroutine.
- Add `aiofiles.os.path.abspath` and `aiofiles.os.getcwd`.
[#174](https://github.com/Tinche/aiofiles/issues/181)
- _aiofiles_ is now tested on Python 3.13 too.
[#184](https://github.com/Tinche/aiofiles/pull/184)
- Dropped Python 3.7 support. If you require it, use version 23.2.1.
#### 23.2.1 (2023-08-09)
- Import `os.statvfs` conditionally to fix importing on non-UNIX systems.
[#171](https://github.com/Tinche/aiofiles/issues/171) [#172](https://github.com/Tinche/aiofiles/pull/172)
- aiofiles is now also tested on Windows.
#### 23.2.0 (2023-08-09)
