Lots of plugins put up the banner including: CA, File Manager, FCP, Recycle Bin, etc.
The changes recently were to fix some issues with the Unraid 6.10 release and changed ids of UD devices.
When I see something that causes users issues, I will release an update. I try not to do a lot of unnecessary updates, but sometimes it's really necessary.
The idea behind the banner is so users will keep plugins up to date. If that is not done, there will be posts about issues that have already been solved because users don't update.
