I don't recall when patreon versions go to public. But if I want to take a guess considering other projects I follow do stuff like patreon first and public later. There's few ways that this can go. 

2 weeks to a month after patreon gets it. At the earliest 

Latest, probably when patreon gets the next version then the previous version goes public. 

And if the last one is the case, we will definitely be waiting a little while. 

However, I'm not the developer and I don't know what the thought process is here for public releases and patreon releases. So only they can provide the answer. I'm just giving what I saw in other projects. 

(If the developer by chance does read this, my intentions were not to offend how you have your stuff set up, this was just an educated guess to give an answer to someone who asked a question).
