There is a comma after the last member of a list on line 14 of release.json. Trailing commas are not legal JSON, and this is breaking some tools - I use CurseBreaker to update addons and it's throwing a parse error here.

Fixed in e8543bd

Thanks again for the fast notice @tseufert1 ❤️

Thanks for the hint @tseufert1 will fix that as well in a minute. The release is broken entirely.
