Manually Changing the Default Version for Libraries
In most cases where you have multiple versions of a pluggable library or a pluggable view library in MashZone NextGen, you manage which version is the current default when you import a version of the library. The current default version determines which libraries are used with pluggable views and the basic or workspace apps that include these views.
You can manually change which version of a library is marked as the default version, if needed, in both the Pluggable Libraries and View Libraries screens in the Admin Console.
1. Click 
Admin Console in the MashZone NextGen Hub main menu. 2. Expand the Platform Features section and open Pluggable Libraries or View Libraries.
3. Find the pluggable library or pluggable view library you want to update and click 
Edit for that library. 4. Select the version you want to use as the default version in the Version property and click Save.
