What
The 'Peer address' line shown in a debug/info panel has been simplified. It no longer includes the hint text '(details in the --debug log)', and the way it describes why the address is unavailable has been reworded to be simpler.
Why
This is a small display cleanup. If you were used to seeing a pointer toward the --debug log next to 'Peer address', you won't see it anymore; the unavailable-reason text itself is just presented more simply now.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say what the new unavailable-reason formatting looks like, only that it was simplified.
