Actually it is being updated nearly every day. It is just that they are refactoring the app, so the new version is currently still in alpha. But you can already try it out if you like. More info here: Questions about the upcoming database version
Publishing will be part of the new version of the app, though I think it might be a “pro” feature: part of the plan to make future development of the app sustainable, along with sync and real time collaboration.
But I won’t write more about the refactoring in this thread, which is focused on the current MD version for now.
