+* Compare setup.cfg configuration ([2bf144a](https://github.com/andreoliwa/flake8-nitpick/commit/2bf144a))
+* First warning, only on the main Python file ([0b30506](https://github.com/andreoliwa/flake8-nitpick/commit/0b30506))
+* Read config from pyproject.toml, cache data, run only on one Python file ([265daa5](https://github.com/andreoliwa/flake8-nitpick/commit/265daa5))
+* Read style from TOML file/URL (or climb directory tree) ([84f19d6](https://github.com/andreoliwa/flake8-nitpick/commit/84f19d6))
+* Respect the files section on nitpick.toml ([9e36a02](https://github.com/andreoliwa/flake8-nitpick/commit/9e36a02))
+* Use nitpick's own default style file if none is provided ([4701b86](https://github.com/andreoliwa/flake8-nitpick/commit/4701b86))
