Release 3.14.11 adds MODBUS RS232 protocol support for newer APC UPSes. This release also adds digital signatures on the Windows USB driver and the Windows installer package which should make installation on recent versions of Windows easier.
The MODBUS protocol gives access to advanced UPS features on newer UPSes that previously only supported Microlink. A firmware upgrade may be required to enable MODBUS support on some UPSes. Please see the ReleaseNotes for further details.
