RNGeusEX just posted this on Patreon and on his Discord as well:
Hi everyone, I hope you are all doing well? Today, a quick message to finally announce a date.
The beta of Goodbye Eternity on the new Godot game engine will be released between Wednesday and Friday.
As I mentioned in my previous message, this version of the game will only include the story from 0.7.9. We will try to track down as many bugs as possible before the final release, which will be about ten days later.
No matter what, version 0.8 will be released in December, and I won't go on vacation until it's done.
Until then, take care.
