@PCManticore have you got an idea on how to put a deprecation warning when astroid is used with python3.5?

[Pierre-Sassoulas]

@hippo91, regarding the deprecation warning I would use the following in setup.py:

import sys
import warnings

if sys.version_info.major == 3 and sys.version_info.minor <=5:
    warnings.warn("You will soon need to upgrade to python 3.6 in order to use the latest version of Astroid.", DeprecationWarning)

[hippo91]

@Pierre-Sassoulas definitely a good idea! The message will be printed during install and not at runtime. It's probably sufficient.

[PCManticore]

Approved, but ideally we should remove or change the release date to today.

[PCManticore]

This is already obsolete. My suggestion is to simply backport the code changes but keep the __pkginfo__ and ChangeLog for a separate change in the day of the release.

[hippo91]

@PCManticore i will move back the Release Date in the ChangeLog. However i didn't change the __pkginfo__.
By the way, have you an idea concerning the release date? There are many people waiting for a release that support python 3.9.

[PCManticore]

Thanks. Not right now. I am still going through the latest updates, mails and issues and don't have a clear picture on what's needed for Python 3.9 compatibility. I did notice some Python 3.9 issues specific to pylint though.

Could there be a tag and PyPI release?

Ah, just preparatory changes only it seems.
