Changed

- Require Python 3.5 or a later version. Python 2 and 3.4 are no longer supported. (341 by bbc2).

Added

- The `dotenv_path` argument of `set_key` and `unset_key` now has a type of `Union[str, os.PathLike]` instead of just `os.PathLike` (347 by bbc2).
- The `stream` argument of `load_dotenv` and `dotenv_values` can now be a text stream (`IO[str]`), which includes values like `io.StringIO("foo")` and `open("file.env", "r")` (348 by bbc2).

Changed

- Raise `ValueError` if `quote_mode` isn't one of `always`, `auto` or `never` in `set_key` (330 by bbc2).
- When writing a value to a .env file with `set_key` or `dotenv set <key> <value>` (330 by bbc2):
- Use single quotes instead of double quotes.
- Don't strip surrounding quotes.
- In `auto` mode, don't add quotes if the value is only made of alphanumeric characters (as determined by `string.isalnum`).

Fixed

- Fixed tests for build environments relying on `PYTHONPATH` (318 by befeleme).
