• Much faster downloads (backup console → PC). Saving a game to your PC
  used to reconnect for every small chunk; it now keeps one connection open
  and reads ahead, and pulls folders over several connections at once. A big
  single file roughly doubled to about full network speed, and folder backups
  are much quicker. It also resumes from where it left off if the connection
  drops. Nothing new to send to your PS5 — it's all in the app.
• See which console each upload is for. Every item in the upload and
  install queues now shows its target console, so a mixed queue isn't a
  guessing game.
• Upload to several consoles at once (optional). New setting under
  Settings → Upload to send queued games to different consoles in parallel
  instead of one console at a time. Off by default.
• Pick a payload version — and downgrade. The Payloads catalog now lets
  you choose any past release of a payload, not just the latest, and flags
  pre-release builds as possibly unstable. Handy for rolling back when a fresh
  build misbehaves.
• Adding a game's update no longer clashes with its base. A base game and
  its update share an ID, which made the app treat an added update as the base
  again. They're now kept separate, with clear "Update" / "DLC" labels.
• Tidy up the staged-package list. New "Clear finished" and "Clear all"
  buttons, plus an optional "auto-delete after install."
