setuptools recently mandated checking for newlines: pypa/setuptools@a4b7cae

We're observing errors while installing skcriteria with setuptools:

It seems the latest release on Pypi 0.2.11 has this issue

>>> import skcriteria
>>> skcriteria.DOC
'Scikit-Criteria is a collections of algorithms, methods and\ntechniques for multiple-criteria decision analysis.\n\n'
>>> skcriteria.VERSION
'0.2.11'

whereas the current master does not:

scikit-criteria/skcriteria/__init__.py

Line 12 in 32fb631

techniques for multiple-criteria decision analysis."""

I just uploaded the version 0.5.dev0, i still need to write a simple "quickstart" and in this week the version 0.5 must be published

[leliel12]

Version 0.5 published! please check the new tutorial https://scikit-criteria.readthedocs.io/en/latest/tutorial/quickstart.html

Thank you for the new release.

Setuptools also has a new release (pypa/setuptools#2893 (comment)) to fix the originally reported issue. I'll close it now.
