Unstable
An 'unstable' version of an application is otherwise known as a 'beta' version. Although it can be shown to the public, it is only suitable to those who want to use the absolute latest features.
Unstable versions are named that because they may have minor or even significant bugs that may prevent the software from working correctly.
We suggest you only use the unstable version of the ARDI product if you need to access the latest features for your application.
