Before the series, a bunch of machines create an if=3Dsd,index=3D0 drive by default even though they cannot use it. HMP "info block" shows it: sd0: [not inserted] Removable device: not locked, tray closed "By default" means -nodefaults suppresses it. After the series, this default drive is gone. That is all. Correct? The commit message could be clearer about this. Perhaps: hw/boards: Do not create unusable default if=3Dsd drives A number of machines create an if=3Dsd drive by default even though they lack an SD bus, and therefore cannot use the drive. This drive is created when the machine sets flag @auto_create_sdcard. Delete that from machines that lack an SD bus. Listing the affected machines might be useful. Worth a mention in the release notes? I don't know.
