Thank for the response. Luckily I’m not on a deadline. Normaly it is not a problem to upgrade because the editor is pretty stable. In the 4.14 release are some more noticeable bugs as before (at least for me) what is fine. If I can’t release this month then I’ll wait. In a real production environment I also would prefer to stay with the engine version unless its necessary to upgrade. In this case its “only” a spare time project where I don’t loose money when I’m not releasing :).
