In version 4.4, keyboard shortcuts moved from being saved per-profile to one shared set for the whole app. If you're updating **from before 4.4**, RemSound now offers — the first time you run it — to **bring your shortcuts across** from one of your existing profiles: it lists your profiles, you pick the one you set your shortcuts up in, or choose to start fresh. (If you already updated to 4.4, nothing changes for you here.)
## A clearer Keyboard shortcuts dialog
- A new **Clear this shortcut** button next to Close, so clearing a shortcut is discoverable — you no longer have to know the Del key.
- When you're setting a shortcut, pressing **Delete** in that box now leaves it unassigned.
## Clearer remote-control labels
The three remote-control rows that adjust a peer's **RemSound** volume now say so — "Send remote RemSound volume up / down to peers" and "Send remote RemSound receive mute toggle to peers" — so they're easy to tell apart from the "Windows global volume" rows.
**v4.5 talks to v3.3 through v4.4 with no trouble** — the over-the-network format is unchanged, so you don't have to update both ends at once. (Everyone still needs **v3.3 or newer**, where end-to-end encryption came in.)
3. Extract the zip **over your existing RemSound folder**, overwriting program files when prompted. The zip is program files only — it won't touch your settings, profiles, logs or recordings.
**From v3.6 or newer:** Help → Check for updates installs v4.5 with the in-app updater — and if it can't finish, it puts your old version back exactly as it was.
**From v1.9–v3.5:** Check for updates works, but uses your current version's older updater for this one hop. If auto-update has been failing on your machine, install by hand using the steps above.
**v1.8 and earlier:** the auto-updater in those versions can't install updates — install by hand using the steps above.
