It is too confusing what that means. People trying Godot beta, be it 3 or 4, are better off cloning and trusting the github repository and pulling and compiling any time and for any OS they want.
The repository changes daily, old bugs squashed, new ones added 😎 , it probably is already newer in the repository than the above link at the time of writing.
Compilation is a matter of 10-12 minutes on a mid-range PC.
