Or is it only available in 4.0+?
@locationforums Since ActivityPub integration required quite a few non-trivial changes to NodeBB core, it is only available in v4.0.0.
v4 will contain only ActivityPub integration. Fixes and new features added to NodeBB during developement are done to v3.x and then pushed to the activitypub branch.
Thank you for the response! This feature has me very excited but please don't mistake that for impatience. To clarify, unless I run my forum in beta, I can't integrate ActivityPub. Is that correct?
@locationforums That's correct. You would have to switch to the activitypub branch to take advantage of this functionality. While you can switch back to master or whatever v3.x code, the data store might have changed, and so going back to v3.x is untested.
