Hi 10leej , right now its only available if you upload via our
API. If you upload and update with a classic toc api version under `compatible` it will be added as a classic download option to your main retail download.
https://api.wowinterface.com/addons/update
Code:
"compatible": {
"Type": "STR",
"Required": "No",
"Description": "Comma delimited list of all patch numbers your AddOn is compatiable with. If you provide the classic version number it will tag your upload for classic.",
"list": "https://api.wowinterface.com/addons/compatible.json"
},
Limitations are you wont have a seperate changelog, description or comments and if you *only* have a classic version to offer then you need to upload the normal route.
