Hi, is there a documented process on how to upgrade the provider plugins for a specific stack?

To first approximation, you should only have to worry about the package versions. The corresponding plugins should be automatically acquired as needed. So the process is just to update your npm/pupils/etc package version and then redploy. If you are seeing that not accomplish what you want - it would be great to understand more about what you are seeing.

I was seeing a specific version of the provider in the state file of a specific stack. I was hoping to be able to run a preview with a newer provider, as there was a bug in the older provider I was using.
