Upgrading Gateway to v8.5

[PhilG]

I have the Gateway up and running from the pre built image (v8.1).  Has anyone tried upgrading to v8.5 over and existing installed and running v8.1?  Do I just copy the v8.5 files over the existing files in /home/pi/gateway and configure the settings in the Web app or are there other steps?

I would backup your working setup first.
Then you can try updating the changed files. Please see the releases github page and there you can see the changes as well.
It will be a good idea to run npm update in the gateway dir to update the npm dependencies.
I would also look at the gateway category posts for information and more details on changes.
