Does anyone know how to access the patch notes when this game updates?

I've been having fun with the game so far, even in the early access state, but I'd love to be able to keep up on development too :)

You can find the patch notes here: https://store.steampowered.com/news/app/600610?updates=true

If a developer wants to collect money from gog customers during an EA period, they should be required to provide support on gog forums. You want to support devs like this, knock yourself out.

Go read the patches on steam, go check out all the discussions and updates and progress reports on steam, see their roadmap on steam, troubleshoot your problems on steam.. And then pay them on gog?
