Addons are added to categories (inventory, attributes, combat, ...) here at
www.esoui.com -> And thus also within the addon manager Minion.
The addon category "Outdated & Discontinued" means: This addon is not working anymore or not worked on anymore. Feel free to use it as long as it works but do not expect any update, error fix or other work on it anymore!
Better move on to a replacement addon.
You can see the category at the top of each addon -> breadcrumbs at the website.

And at the addon search as own column:
And at the category search as well
Important - Minion and "Outdated & Discontinued"
Minion will not show addons in that category at all!
Minion3 is NOT telling you that an addon was moved to outdated meanwhile -> it's not able to do such (technically)
If you have any outdated & discontinued addon in your live/AddOns folder it's most likely because it was already installed before it was moved to the outdated & discontinued category, and you did not notice.
You are responsible to check your addons for outdated/discontinued state yourself! At least once a year this makes sense.
