Release Notes - v2.0.0

🧩 Note on the Chrome Extension

A few things to keep in mind about scope:

The extension is a lightweight companion, not a replacement for the native desktop app. It is not feature-complete and is not intended to cover every workflow the desktop client supports.
Supported: using the extension as a lightweight in-browser clipboard manager, and pairing it with the native desktop app to sync clipboard content across devices.
Not supported: extension-to-extension cross-device pairing. Two browsers running only the extension cannot sync directly with each other — at least one peer in the mesh must be a native CrossPaste desktop (or mobile) instance.

If you need the full cross-device experience, install the native desktop app on at least one of your devices and pair the extension to it.

🧩 Chrome Extension — A Brand New Platform
CrossPaste now runs as a first-class Chrome Extension, bringing clipboard sync directly to the browser. Includes WebSocket-based file pulling, Native Messaging to pause the extension when the desktop app is running, and full SyncState parity with desktop (#4152 #4157 #4158 #4164 #4168 #4176).
🔐 SAS-Based v2 Pairing Protocol
Pairing now uses a Short Authentication String (SAS) to prevent MITM attacks, with a showPairingCode endpoint and a remote access toggle for safer device onboarding (#4088 #4096 #4098).
🔄 WebSocket Sync Protocol
A new bidirectional, real-time WebSocket sync channel replaces polling for many flows, enabling instant cross-device updates, batch pulls, and live liveness probes (#4112 #4120 #4223).
🖥️ Redesigned Devices Screen
The devices screen has been rebuilt with offline grouping, a current-device dialog, and a refined add-device flow — a cleaner, faster way to manage your mesh (#4207).
🏷️ Namespaced App Source Icons
App source icons are now namespaced by appInstanceId, eliminating cross-device collisions and enabling correct icon rendering across heterogeneous meshes (#4191 #4193 #4197).
