• Installs wait for the PS5 to be ready — fewer "couldn't be applied" errors.
  Right after an install the PS5 has a brief recovery moment (the screen-black
  blink); starting the next install during it was getting rejected with a
  transient error, so you'd have to wait and retry by hand. ps5upload now checks
  the console is settled before it installs, and if the PS5 says it's busy it
  waits and retries automatically instead of failing — so back-to-back updates
  and DLC just work. (Shows "Waiting for the PS5 to be ready…" while it waits.)
