That seems to be the most stable current version right now. Everything else that's newer causes program breaking issues. Not really sure what's going on with this company as it's been 6 months without an updated stable version. Just make sure you put your show through a bunch of tests to make sure. I run my bands lights with midi cues, and there's nothing more embarrassing than having to restart a program between songs because the program is causing the lights to malfunction.
