Stacks define various aspects of how Node-RED instances run - including the version of Node-RED being used.
FlowForge allows you to change the stack an instance is using - providing a way to upgrade Node-RED.
Note: Stacks are created by Administrators and made available to the teams and users of the platform.
When an Administrator creates a new version of a Stack your instance is using, the platform will notify you that there is a new version available.
To change an instance's stack:
Your instance will now be restarted on the new stack.
Note: Changing the stack causes Node-RED to be stopped and restarted. This will require a short downtime of the flows.
