I hope the updates are taking so long because the developer is preparing something big. Maybe someone knows something about this?

i mean you can try it if you want its  just in public testing rn
though nose  will make very very sure your aware that its a buggy build before u can play it (tho with it at 9.0d at this point its  probbly alot less buggy from when i first tried the 9.0 shadow builds (9.0b))

0.9e is out right now. It'll probably take a while for a stable 0.9 version to be released, but you can play the unstable version if you want to.
