Synergy 1

v1.20.4 (June 12, 2026)

Enhancements

• Personal licenses now activate once online and then work fully offline, so the app keeps running on restricted or disconnected networks.

v1.20.3 (June 8, 2026)

Features

• Wayland users now keep their input capture session across config changes, so permission stays alowed without needing to re-grant each time (requires latest Wayland libraries).
• Added a setting in Preferences that lets you choose between the stable update track or the beta track for receiving new releases.

Enhancements

• Installations now run natively on Ubuntu 26.04.
• Support has been extended to Fedora 43 and Fedora 44.

Bug fixes

• Restored the ability to send Ctrl+Alt+Del to a Windows client (when using hotkeys and elevated permission).
• Addressed a crash on macOS that caused the cursor to bounce back when moving between screens at a screen edge.
• Eliminated a crash on macOS triggered while the screen saver was starting up.
• Fixed horizontal mouse scrolling so it again works on a Windows client.
• Reduced the frequency that the Windows daemon causes unexpected response "ok\nok\n".

v1.20.1 (May 4, 2026)

Bug fixes

• Eliminated a local privilege escalation path that let unauthenticated users gain elevated system access (CVE-2026-41477).
• Patched a clipboard memory safety vulnerability that could be exploited to crash the program or run malicious code (CVE-2026-41476).
• Corrected a denial of service (DoS) vulnerability where a TLS server and its connected clients became unreachable when a non-TLS client attempted to connect (CVE-2026-44296).
• Stopped newer clients from being incorrectly rejected with an incompatibility error when connecting to the server.
