Tried my first upgrade with Central yesterday. It seemed to work, only a small step from 25.10 to 25.10_2.
But there doesn't seem to be any useful information in Central about this. There is no log and after clicking Upgrade I wasn't really sure what it was doing. The "Ready to upgrade" and "Upgrade in progress" icons are the same colour which seems like an obvious missed opportunity. We know that new colours are quite cheap nowadays.
