- The launcher keeps a log (/data/tailscale/launcher.log) and shows a notification when it cannot start. A payload manager does not show what a payload prints, so a failed start used to leave no trace. The Go runtime's stderr goes to the same file until the daemon opens its log. - New setting "who on the tailnet may connect": every device the tailnet's access rules allow (default), or only devices of the same user as the console. Applies to every forwarded TCP port, the UDP ports and the status page over the tailnet. - The status page shows when the console's key expires and warns from two weeks before; the console shows a notification at 14, 3 and 1 days. - A newer release is announced once on the console, not only on the page. - Status page: click an address to copy it; OS, status and address columns no longer break mid-word; the facts stack on narrow screens.
