I have been confused for a while now about the update process and in particular what is documented when you either click on the red notification that tells you an update is available or you go Settings>Check for Updates. Today I realized why this documentation has confused me so much in the past. The description of changes is not complete and since there is no link to the actual release notes I have always assumed that what the hub is telling me is the purported changes to the platform that my Hubitat Elevation wants me to update to. That is an incorrect assumption.
Feel free to tell me that the assumption I made was not appropriate based on something. I'd love to hear it. But otherwise I cannot understand why the platform update process completely disregards and does not disclose all of the changes that the developers have indicated as relevant enough to post on the community forum.
I didn't do a line by line comparison but I'm sure that the platform upgrade description for the current update to 2.2.9.129 is the same as the initial release notes for platform update 2.2.9. Not the release notes and the subsequent post but just the original announcement. So why in this case are they telling me all about the updates to the platform but not the updates to the platform that my C-7 wants me to update to (e.g., 2.2.9.129 which includes the apparent release today)? For the avoidance of doubt, I did check the end of the text included on the update screen (xxx/hub/platformUpdate) and the last line says " * Chromecast reconnect and status poller tweaks." but that is not the final word on the changes to " New Version Available: 2.2.9.129" which is prominent on the update screen.
