What is new in Scarf 3.6.0

# Scarf v3.6.0

This release is about trust and readability. **ScarfGo now checks the identity of every server it connects to**, closing a gap where it would have accepted a server pretending to be yours. Both apps got a contrast pass so buttons, status text and warnings are readable in light and dark mode. The privacy policy and the in-app privacy text were rewritten to match exactly what the code does, which means Live Voice will ask for your consent once more. And Mac users still on macOS 14 Sonoma are no longer offered updates that can't run on their Mac.

## ScarfGo now verifies your server's identity

Until now, ScarfGo didn't check a server's SSH host key, the fingerprint that proves a server is the one you paired with. On a network someone else controls, a machine pretending to be your Hermes host could have been accepted, and it could then read and change what ScarfGo sent, including your chats. The Mac app was never affected: it uses the system `ssh`, which has always checked host keys.

ScarfGo now behaves like the Mac:

- **The first time it connects to a server, it remembers that server's key.** Servers you paired before this update are remembered on their next connection, with nothing for you to do.
