No specific info about version 1.6. Please visit the main page of Action! on Software Informer.
Action! Mirillis is a cool tool. Newest 2.0 version has many excellent features like streaming to facebook and youtube, greenscreen mode (you can cut out the background), possibility to record only the application you want to show to others not the whole desktop and many others. I think it's worth having.
New Version of Action supports a wide range of output audio, video and picture formats so you can remove your cons and add new version Mirillis Action 1.12.1 to your database. Take care.
