Pretty self-explanatory it's a poll voting that decide if they want dev to release a beta version of the update. Looks like it won't update anytime soon, except if the beta gets leak or something.
I figured as much but i've seen a variety of beta release polls that it could have been. some have been "for the next beta cut content and release sooner or delay until all planned content is included"
some have been "what would you like included in the game before next beta is out" or even "how debugged and refined do you believe a beta should be released before given to subscribers?"
the last one being a hot topic because I saw a beta got published in a still moderately buggy state on another game once. then it got leaked and everyone dogpiled the developer for releasing a mess of an update and he had to clarify that it was an unfinished update for bug testing and that it was leaked. not released. now making it so the primary purpose of betas became scary because now if it's buggy and gets leaked, people judge it for being poorly polished. but if they fully polish betas then what are the beta players supposed to do? just give positive affirmations to jerk off the dev before full release?
the game is only on version 0.2. who knows how refined the dev's production, beta testing, and release scheduling is.
