Pywikibot is dropping Python 2 support soon. The framework is ready to use with Python 3 including all the scripts inside the scripts folder.
All bot owners are invited to merge to Python 3 too. If you need any help for your own scripts to migrate, ask here for support.
If you need more time for migrating you can still use pywikibot with an older release tag.
The last stable release for Python 2 is marked with tag python2.
