As a fork our version doesnt track mainstream anymore. So it is not an indication that we are "behind". We take in features and bug fixes piecemeal.
That said there are some new features we have yet to pull into our fork. We are actively working on that now. I am trying to hire a developer to help me and have one who is interested (a mastodon dev).
A few things actually. @trinsec and I recently discussed it and saw a few things we really want. Post translation was very appealing, as was being able to properly edit posts.
@freemo Translation is a big one. I am usually on the "against" side of editing, not that my opinion means anything. @trinsec @JoshuaACasey
@freemo Was there anything you saw in 4.0 that you thought "I need that" @JoshuaACasey
