Kind of getting frustrated at this point and want to see an officially released version, but I appreciate the time and effort going into this update and all the pre-release bugs that would’ve ended up in the official update. Here’s Jeb’s Twitter post about the release (with links) and I’ve made the links easier to click below along with a list a fellow redditor put together.
