CouchPlay, a split-screen multiplayer tool for Linux, has been released in version v0.6.1.
The update directly follows version 0.6.0 with Moonlight streaming and mostly brings fixes: library sharing is skipped for players who have never started Steam, the helper uses the desktop’s real Wayland socket, and there is a new update checker with “Update now” for Flatpak. Active local sessions can also manage sessions without a password prompt, and the Meta+Shift+Escape stop shortcut is now documented.
The GitHub release notes only contain the title “CouchPlay 0.6.1”; the details come from the commits since v0.6.0.
