It's month by month. Whatever updates we do to it between the month's big update - next month's big update. So on or after the 8th when we update the public again, you'll have to pay for it again. To be in line with how patreon works.
This month will be another update to Maddox with some more events we want to get in + any bug fixes of course, and hopefully soon access to the web version.
It's just a way to support so don't feel like you need to. Anything that comes out on patreon will come out for public later.
