Release notes for beta versions of Litchi?

Hello, I am using the stable latest version of Litchi, but I also want to see which changes are made to the beta, so if I see a feature I like I will join Beta.
I know that the stable version release notes are on the official litchi website, but where can I find the beta release notes before I actually go and update to beta?

The beta changelog is currently only available in the play store when you are a beta tester
