Copssh version 4.2.2 is a minor update and contains updated versions of bash and readline7.dll, fixing broken backspace in bash shell and a non-working nano editor.
In addition, the Windows firewall is automatically configured for communication on port 22.
Furthermore, Copssh installer instructs Vista/7 platforms to run it with administrator privileges (no need to specify "Run as administrator" or disabling UAC (User Accont Control)). You need, however, still to run the Control Panel as an administrator for a proper operation.
Uninstaller logic is also updated for removal of the firewall exception and the service account upon request.
