. A full month earlier than expected. That update is one version ahead of what Patreon's prior latest was, but one version behind the Patreon update that was released at the same time. (In other words, between the now most recent Patreon update and the one prior)
Why did it come out early? We don't actually know, and can only make assumptions. The last time we got a wonky out-of-cycle update was July of last year, when the developers pushed an update specifically to add playable male characters for Steam. That created a situation where Steam got updates in June, July, then October and finally December of last year, rather than the expected June, September, and December for quarters 2-4.
