There was some federation issues that are getting fixed plus a couple other bugs that need to get fixed before we update so site behavior doesnt break (e.g. show read posts not working). I assume we would update sometime after Christmas since 0.19.1 is in release clients and so we aren't dealing with maintenance over the holidays
Edit: seems like 0.19.1 released today, still likely after Christmas due to the second reason and so that can be checked to make sure there's no issues still
