 - Relicensed Herdr from AGPL-3.0-or-later to Apache-2.0.
 
 ### Fixed
+- Pane text copied through VS Code Remote Tunnels now reaches the viewing machine's clipboard instead of overwriting the remote host clipboard. (#2015)
 - Windows agent detection now follows Git Bash-launched agents across emulated `exec` process boundaries. (#2107)
 - Detached Windows servers and pane processes now survive logout from the OpenSSH session that started them. (#2008)
 - Windows `agent start` now launches agents without native arguments instead of timing out on an invalid empty PowerShell argument list. (#2072)
