Hi, I am sending this mail to encourage reviews in horizon plugins. - Drop python 2.7 and Django 1.11 - Remove six usage Horizon has dropped python 2.7 support and Django 1.11 support (which is the last version with python 2.7 support). We proposed changes to horizon plugins to catch up with these changes. - Most projects have merged them. Thanks for your cooperation. - There are several pending reviews. https://review.opendev.org/#/q/topic:drop-django111-support+status:open - Django 1.11 drop depends on python 2.7 drop. In case of karbar-dashboard, python 2.7 drop needs to land before it. https://review.opendev.org/#/c/694442/ horizon also has dropped six usage. There are plugins which depends six on horizon requirements. We proposed a series of changes to avoid UT breakages in plugins. Reviews on them are also appreciated. https://review.opendev.org/#/q/topic:remove-six+status:open Thanks, Akihiro Motoki (amotoki)
