- Denkovi (FT245 D2XX) now selectable as 4 or 8 relays (a 4-relay board just uses the low nibble); NewDenkovi takes a count, driven by the device's Channels. - New 'usbrelay' backend: cheap CH340/LCUS USB-serial boards over a COM port using the common A0 protocol ([0xA0][relay][state][checksum]); write-only, so Status is a shadow. Channel count configurable (1/2/4/8/16). - StationDevice gains Channels; deviceRelayCount() drives label/relay counts for the variable-size types. Device editor: channel selector + COM-port picker (usbrelay) / FTDI-serial (denkovi). Both untested on hardware; the A0 command set / Denkovi bit order may need a tweak after a live test.
