What do you mean by 8.3 for a release date could you be more specific like is the 8 the day of the month and the 3 the actual month of the year or is it the other way around where the 8 is the month and the 3 is the day?
Like some other game devs, he/she/they will wait about one month after releasing an update on Patreon before uploading it to Itch, so here "8.3" is indeed the 8th of March...
