Someone know how to enable beta branch for 0.3xxx ? Since save games from 0.3xxx dont work on 0.4xxx - as I understand.
Update:

"Manage Installation -> Configure

Uncheck "Automatically update to newest version" and you will be able to manually pick which version you want to play.
The last 0.3X version is there, 0.3.134"
