It is a good idea to download and use the latest beta version, because it contains the latest bug fixes, there are tons of new features, and it is updated frequently. However the beta version may contain bugs in new functionality.

Download

The beta version is compatible with macOS 10.7-10.13.

Note: the application name did not change (RapidComposer.app), so please make sure you won't overwrite the stable application with the same name.
