Deprecated API Calls
Please provide any additional information below.
Blizzard has depreciated several APIs that tie into addons. most of which now are C_AddOns.TheDepreciatedAPI
What version number of Can I Mog It is installed? 10.1.5.v1.53
I noticed that you use IsAddOnLoaded for all the supported addons in the Plugins folder, and it might exist elsewhere.
Another API that changed is GetAddOnMetadata, which is now C_AddOns.GetAddOnMetadata. I didn't look if you use it; however, I thought I would add it to the bug report just in case.
Here is the current list of C_AddOns APIs which were changed: https://warcraft.wiki.gg/wiki/Category:API_namespaces/C_AddOns
