Please attach a zip file as a binary when you create releases so that addon updaters such as WoWUp can retrieve new versions. I've created a zip file using github and attached it to this ticket if you would like to add it to the latest release.
minarch-9.2.0.zip
If you would like to receive support though addon sites such as Curse, I would ask that you please consider using other sites such as wago.io in addition to Curse.
Thank you.

Starting with v10.2.8 (soon to be released), zip files will be attached to releases. I also enabled distribution outside of the Curse ecosystem.

(EDIT: I was trying to release it this week, but the Curse auto-packager is currently having some troubles, I contacted their support, hope they'll fix it soon)

Thank you for your time and effort in doing this!

Should be available on Wago now. Does anyone know if I need to do anything else to make it available on WowUp?

WowUp can pull from Wago and since you're now including the zip file in github, WowUp can also be pointed to the releases section here and it'll grab the newest zip file release.

It's now available on WowUp as well, thanks for the info.

Second this. Would be lovely to be able to use Cursebreaker to update the addon. Thanks in advance!

Like to push this a little bit - It would be very nice when we can Update this Addon via WoWUp :)
