Given curseforge blocking wowup from tracking, it would be nice if your github releases follow the wowup github requirements (https://wowup.io/guide/get-addons/overview) by ending the TBC zip file in -bc.zip

I do not see any issue with -bcc.
When using github with wowup it supports the -bcc suffix for quite a while now.
If you don't want to use curseforge, CLM is uploaded to WoWInterface and WAgo AddOns also, to choose from.

Update: it appears wowup authors have found the issue! Thanks for the quick reply @lantisnt

Heya! I've added a summary of the issue here: WowUp/WowUp#1107 (comment)

Currently the WowUp app doesn't support the content type of the zips in the latest release (application/octet-stream). I'm not sure how the zip was created, so if it's causing issues right now it could be fixed that way. I don't think a new release would be needed, can just re-attach the zips.

Posting here for reference, since it is also being discussed at WowUp discord.

All releases are done using the BigWigs Packager https://github.com/BigWigsMods/packager thus issue might be global.
