Im probably just an idiot but on a thread: https://github.com/ReplayMod/ReplayMod/issues/238 it says that 1.16 full release is today but when I went to https://www.replaymod.com/download/ the latest is 1.15.2 how do you find 1.16 release? thanks.

You don't atm unless you're a Patron on VIP level, see my reply on the thread you linked.
