Thanks, @baris! Happy to help.
Why doesn't NodeBB provide tags since 1.2.2?
There is some problems on regarding to socket.io, so I need to revert code to see the changes between previous version and the latest, but unfortunately, NodeBB officials does not provide such tags since 1.2.2? I want to know how could I get previous stable version of forum code when possible?
Sorry, it seems that git tags does not shipped with code. So downloaded tags are not completed, when I tapped
However github has its completed tags.
