Just because a relatively high-tier patron chose to leak his updated game on this pirate forum does not mean the dev has to take official notice and change the release process to his patrons. As far as I can tell, he hasn't officially released this to his last group of patrons, meaning his public release may still be a couple of weeks off. My assumption (and it is just that, an assumption on my part) is that he wouldn't release the next version until the previous one has officially gone public.
Similarly, I see no posts yet talking about when the next update will be released. In theory, that may mean that he's on whatever schedule he set in the fall (I am not a patron, so I can mostly see that posts exist, and their titles (and dates)). In practice, he may want a gap between the public release of this update and the initial release of the next; or, there may yet be work to be done. Again, as many others have said, after the better part of a year of silence, it remains to be seen if he truly is motivated to bring the current "season" to a close, and is really started on a more organized and consistent "season 2" - or if he wanted a boost to his end-of-year/Christmas income, and (perhaps having accomplished the same) now will fall off the radar again. Trust, once lost, requires effort to regain.
