### 4.3.5 - February 24, 2019 - last Python 2.7 Maintenance Release

This is the final Python 2.x release of isort, and includes the following major changes:

Potentially Interface Breaking:
- The `-r` option for removing imports has been renamed `-rm` to avoid accidental deletions and confusion with the `-rc` recursive option.
- `__init__.py` has been removed from the default ignore list. The default ignore list is now empty - with all items needing to be explicitly ignored.
- Isort will now by default ignore .tox / venv folders in an effort to be "safe". You can disable this behaviour by setting the "--unsafe" flag, this is separate from any skip or not skip rules you may have in place.
- Isort now allows for files missing closing newlines in whitespace check
- `distutils` support has been removed to simplify setup.py

New:
- Official Python 3.7 Compatibility.
- Support for using requirements files to auto determine third-paty section if pipreqs & requirementslib are installed.
- Added support for using pyproject.toml if toml is installed.
- Added support for XDG_HOME if appdirs is installed.
- An option has been added to enable ignoring trailing comments ('ignore_comments') defaulting to False.
- Added support to enable line length sorting for only specific sections
- Added a `correctly_sorted` property on the SortsImport to enable more intuitive programmatic checking.

Fixes:
- Improved black compatibility.
- Isort will no detect files in the CWD as first-party.
- Fixed several cases where '-ns' or 'not_skip' was being incorrectly ignored.
- Fixed sorting of relative path imports ('.', '..', '...', etc).
- Fixed bugs caused by a failure to maintain order when loading iterables from config files.
- Correctly handle CPython compiled imports and others that need EXT_SUFFIX to correctly identify.
- Fixed handling of Symbolic Links to follow them when walking the path.
- Fixed handling of relative known_paths.
- Fixed lack of access to all wrap modes from the CLI.
- Fixed handling of FIFO files.
- Fixed a bug that could result in multiple imports being inserted on the same line.
