The release notes could probably use some tweaking here. It looks to me like pg_dumpall (and hence pg_upgrade) will adjust the ownership and permissions of template1's public schema to match what was in the old installation, but it doesn't touch template0. Hence, whether a "newly-created database in an existing cluster" has the old or new properties of the public schema will depend on whether you clone it from template1 or template0. That definitely needs explained, and maybe we should recommend that DBAs consider manually changing what's in template1.
I didn't see any changes related to this in the first draft of the 15.1 release notes. Since I got the impression from the above that there might be a change, I'm sending this as a reminder.
